For example, 1 green blink followed by 5 red blinks is channel 15. Channel unassigned is represented by constant orange on the Status LED. 5) Change transmitter channel to channel unassigned by pressing PB4 one time

(Status LED displays constant orange). 6) Transfer channel unassigned setting to the receiver by rotate and hold the power switch key at START position until the Status LED turns to constant green (transfer complete). Turn off the transmitter power if constant green is not shown on the Status LED after more than 10 seconds (transfer incomplete); the transmitter will revert back to its previous channel setting. Make sure the receiver power is turned on and within the operating distance during the entire process. When transmitter is set to channel unassigned the receiver must also set to channel unassigned in order for the entire system to work. 7) Exit Channel Setting mode by rotate the power switch key to OFF ( 0 ) position. Flex 12ES/EX Standard, AB and Tandem Instruction Manual September 2016 Page 11 of 43 B. Assigned Channel Scheme (preset system channel) Both transmitter and receiver is assigned with a matching preset channel (channel 01~). Pitch & Catch, t-type, and multi-receiver configurations must set to assigned channel scheme. 1) Rotate the power switch key to OFF ( 0 ) position. 2) With the STOP button elevated, press and hold PB1 and PB2 at the same time. 3) Rotate the power switch key to ON ( I ) position. 4) Let go PB1 and PB2 at the same time (entered Channel Setting mode). The Status LED displays current channel setting with red and green blinks. A green blink represents the tens (+10) and a red blink represents the units (+1). For example, 1 green blink followed by 5 red blinks is channel 15. Channel unassigned is represented by constant orange on the Status LED. 5) Change transmitter channel by pressing PB1 to increment the units (+1) and PB2 to increment the tens (+10). For example, press PB2 two times and then PB1 four times is channel 24 (Status LED blinks 2 greens and 4 reds). 6) Transfer the newly selected channel to the receiver by rotate and hold the power switch key at START position until the Status LED turns to constant green (transfer complete). Turn off the transmitter power if constant green is not shown on the Status LED after more than 10 seconds (transfer incomplete); the transmitter will revert back to its previous channel setting. Make sure the receiver power is turned on and within the operating distance during the entire process. Skip step 6 if changing receiver channel is not required. 7) Exit Channel Setting mode by rotate the power switch key to OFF ( 0 ) position. Note: When selecting a new channel, make sure each button press does not exceed 3 seconds. Important Note:

Step 6 illustrated above is strictly required if you are intending to change the entire system channel (both transmitter and receiver). The entire system no longer works if step 6 is skipped because the transmitter and receiver channels are now different (new vs. old). In this case you would have to redo step 1~4 and step 6 to transfer the newly selected transmitter channel to the receiver.

Turn it further counter clockwise to release the key. 6.2. Master/Master Tandem Operation (Tandem models) Receiver B A Receiver To gain control of one or both receivers, first rotate the selector switch to either A, B or A+B position and then execute the START command to activate the receiver MAIN relays inside receiver A, receiver B, or both receivers (depending on the selector switch position). In order to gain control of a receiver, the PITCH pushbutton on the other transmitter must be pressed prior to your takeover. For example, in order for transmitter-A to gain control of receiver-B, transmitter-B must first release its control of receiver-B by first rotate the selector switch to B position and then press the PITCH pushbutton for up to 2.0 seconds. This B action releases transmitter-B control of receiver-B. Transmitter-A is then able to take control of receiver-B by first rotate the selector switch to B position and then execute the START command. Make sure the START command is executed 2.0 seconds after transmitter-B presses the PITCH pushbutton (refer to diagram below).

Once the transmitter is locked on to both receivers, rotate the selector switch to either A, B, or A+B position for independent or simultaneous operation. At beginning of each shift prior to turning on the transmitter power, always check if the selector switch is correctly positioned for the intended receiver or receivers. For safety, there is a 2-second grace period followed after executing the PITCH command. What this means is that after PITCH pushbutton is pressed, executing the START command on the other transmitter within this 2-second grace period is ineffective. In order to gain control of the other receiver you must first wait for up to 2 seconds after the other transmitter presses the PITCH pushbutton and then for you to execute the START command thereafter. 6.3. Master/Slave Tandem Operation (Tandem models) a. Receiver Receiver B A To gain control of one or both receivers, first rotate the selector switch to either A, B or A+B position and then execute the START command to activate the receiver MAIN relays inside receiver A, receiver B, or both receivers (depending on the selector switch position). In order to gain control of a receiver, the PITCH pushbutton on the other transmitter must be pressed prior to your takeover. For example, in order for Master transmitter to gain control of the Slave receiver (receiver-B), Slave transmitter must first release control of its receiver (receiver-B) by pressing the PITCH pushbutton for up to 2.0 seconds. This action releases Slave transmitter control of its receiver (receiver-B). Master transmitter is then able to take control of the Slave receiver (receiver-B) by first rotate the selector switch to B position and then execute the START command. Make sure the START command is executed 2.0 seconds after Slave transmitter presses the PITCH pushbutton (refer to diagram below).

Unassigned Channel Scheme (no preset system channel) When both transmitter and receiver is set to unassigned channel scheme (no preset channel) the system automatically search and lock onto a free and uninterrupted channel at every transmitter startup. Pitch & Catch, t-type, and multi-

receiver configurations can not set to unassigned channel scheme. 1) Rotate the power switch key to OFF ( 0 ) position. 2) With the STOP button elevated, press and hold PB1 and PB2 at the same time. 3) Rotate the power switch key to ON ( I ) position. 4) Let go PB1 and PB2 at the same time (entered Channel Setting mode). The Status LED displays current channel setting with red and green blinks. A green blink represents the tens (+10) and a red blink represents the units (+1). For example, 1 green blink followed by 5 red blinks is channel 15. Channel unassigned is represented by constant orange on the Status LED. 5) Change transmitter channel to channel unassigned by pressing PB4 one time

(Status LED displays constant orange). 6) Transfer channel unassigned setting to the receiver by rotate and hold the power switch key at START position until the Status LED turns to constant green (transfer complete). Turn off the transmitter power if constant green is not shown on the Status LED after more than 10 seconds (transfer incomplete); the transmitter will revert back to its previous channel setting. Make sure the receiver power is turned on and within the operating distance during the entire process. When transmitter is set to channel unassigned the receiver must also set to channel unassigned in order for the entire system to work. 7) Exit Channel Setting mode by rotate the power switch key to OFF ( 0 ) position. Flex 4ES/EX Instruction Manual September 2016 Page 11 of 37 B. Assigned Channel Scheme (preset system channel) Both transmitter and receiver is assigned with a matching preset channel (channel 01~). Pitch & Catch, t-type, and multi-receiver configurations must set to assigned channel scheme. 1) Rotate the power switch key to OFF ( 0 ) position. 2) With the STOP button elevated, press and hold PB1 and PB2 at the same time. 3) Rotate the power switch key to ON ( I ) position. 4) Let go PB1 and PB2 at the same time (entered Channel Setting mode). The Status LED displays current channel setting with red and green blinks. A green blink represents the tens (+10) and a red blink represents the units (+1). For example, 1 green blink followed by 5 red blinks is channel 15. Channel unassigned is represented by constant orange on the Status LED. 5) Change transmitter channel by pressing PB1 to increment the units (+1) and PB2 to increment the tens (+10). For example, press PB2 two times and then PB1 four times is channel 24 (Status LED blinks 2 greens and 4 reds). 6) Transfer the newly selected channel to the receiver by rotate and hold the power switch key at START position until the Status LED turns to constant green (transfer complete). Turn off the transmitter power if constant green is not shown on the Status LED after more than 10 seconds (transfer incomplete); the transmitter will revert back to its previous channel setting. Make sure the receiver power is turned on and within the operating distance during the entire process. Skip step 6 if changing receiver channel is not required. 7) Exit Channel Setting mode by rotate the power switch key to OFF ( 0 ) position. Note: When selecting a new channel, make sure each button press does not exceed 3 seconds. Important Note:

Step 6 illustrated above is strictly required if you are intending to change the entire system channel (both transmitter and receiver). The entire system no longer works if step 6 is skipped because the transmitter and receiver channels are now different (new vs. old). In this case you would have to redo step 1~4 and step 6 to transfer the newly selected transmitter channel to the receiver. Flex 4ES/EX Instruction Manual September 2016 Page 12 of 37 4.1.3.

For example, 1 green blink followed by 5 red blinks is channel 15. Channel unassigned is represented by constant orange on the Status LED. 5) Change transmitter channel to channel unassigned by pressing PB4 one time

(Status LED displays constant orange). 6) Transfer channel unassigned setting to the receiver by rotate and hold the power switch key at START position until the Status LED turns to constant green (transfer complete). Turn off the transmitter power if constant green is not shown on the Status LED after more than 10 seconds (transfer incomplete); the transmitter will revert back to its previous channel setting. Make sure the receiver power is turned on and within the operating distance during the entire process. When transmitter is set to channel unassigned the receiver must also set to channel unassigned in order for the entire system to work. 7) Exit Channel Setting mode by rotate the power switch key to OFF ( 0 ) position. Flex 6ES/EX Instruction Manual September 2016 Page 11 of 37 B. Assigned Channel Scheme (preset system channel) Both transmitter and receiver is assigned with a matching preset channel (channel 01~141). Pitch & Catch, t-type, and multi-receiver configurations must set to assigned channel scheme. 1) Rotate the power switch key to OFF ( 0 ) position. 2) With the STOP button elevated, press and hold PB1 and PB2 at the same time. 3) Rotate the power switch key to ON ( I ) position. 4) Let go PB1 and PB2 at the same time (entered Channel Setting mode). The Status LED displays current channel setting with red and green blinks. A green blink represents the tens (+10) and a red blink represents the units (+1). For example, 1 green blink followed by 5 red blinks is channel 15. Channel unassigned is represented by constant orange on the Status LED. 5) Change transmitter channel by pressing PB1 to increment the units (+1) and PB2 to increment the tens (+10). For example, press PB2 two times and then PB1 four times is channel 24 (Status LED blinks 2 greens and 4 reds). 6) Transfer the newly selected channel to the receiver by rotate and hold the power switch key at START position until the Status LED turns to constant green (transfer complete). Turn off the transmitter power if constant green is not shown on the Status LED after more than 10 seconds (transfer incomplete); the transmitter will revert back to its previous channel setting. Make sure the receiver power is turned on and within the operating distance during the entire process. Skip step 6 if changing receiver channel is not required. 7) Exit Channel Setting mode by rotate the power switch key to OFF ( 0 ) position. Note: When selecting a new channel, make sure each button press does not exceed 3 seconds. Important Note:

Step 6 illustrated above is strictly required if you are intending to change the entire system channel (both transmitter and receiver). The entire system no longer works if step 6 is skipped because the transmitter and receiver channels are now different (new vs. old). In this case you would have to redo step 1~4 and step 6 to transfer the newly selected transmitter channel to the receiver. Flex 6ES/EX Instruction Manual September 2016 Page 12 of 37 4.1.3.

For example, 1 green blink followed by 5 red blinks is channel 15. Channel unassigned is represented by constant orange on the Status LED. 5) Change transmitter channel to channel unassigned by pressing PB4 one time

(Status LED displays constant orange). 6) Transfer channel unassigned setting to the receiver by rotate and hold the power switch key at START position until the Status LED turns to constant green (transfer complete). Turn off the transmitter power if constant green is not shown on the Status LED after more than 10 seconds (transfer incomplete); the transmitter will revert back to its previous channel setting. Make sure the receiver power is turned on and within the operating distance during the entire process. When transmitter is set to channel unassigned the receiver must also set to channel unassigned in order for the entire system to work. 7) Exit Channel Setting mode by rotate the power switch key to OFF ( 0 ) position. Flex 8ES/EX Standard, AB and Tandem Instruction Manual September 2016 Page 11 of 42 B. Assigned Channel Scheme (preset system channel) Both transmitter and receiver is assigned with a matching preset channel (channel 01~). Pitch & Catch, t-type, and multi-receiver configurations must set to assigned channel scheme. 1) Rotate the power switch key to OFF ( 0 ) position. 2) With the STOP button elevated, press and hold PB1 and PB2 at the same time. 3) Rotate the power switch key to ON ( I ) position. 4) Let go PB1 and PB2 at the same time (entered Channel Setting mode). The Status LED displays current channel setting with red and green blinks. A green blink represents the tens (+10) and a red blink represents the units (+1). For example, 1 green blink followed by 5 red blinks is channel 15. Channel unassigned is represented by constant orange on the Status LED. 5) Change transmitter channel by pressing PB1 to increment the units (+1) and PB2 to increment the tens (+10). For example, press PB2 two times and then PB1 four times is channel 24 (Status LED blinks 2 greens and 4 reds). 6) Transfer the newly selected channel to the receiver by rotate and hold the power switch key at START position until the Status LED turns to constant green (transfer complete). Turn off the transmitter power if constant green is not shown on the Status LED after more than 10 seconds (transfer incomplete); the transmitter will revert back to its previous channel setting. Make sure the receiver power is turned on and within the operating distance during the entire process. Skip step 6 if changing receiver channel is not required. 7) Exit Channel Setting mode by rotate the power switch key to OFF ( 0 ) position. Note: When selecting a new channel, make sure each button press does not exceed 3 seconds. Important Note:

Step 6 illustrated above is strictly required if you are intending to change the entire system channel (both transmitter and receiver). The entire system no longer works if step 6 is skipped because the transmitter and receiver channels are now different (new vs. old). In this case you would have to redo step 1~4 and step 6 to transfer the newly selected transmitter channel to the receiver.

Reset the STOP button located on the top left hand corner of the transmitter by rotating it clockwise or counter clockwise, the button will pop up. Turn on the transmitter power by inserting the power switch key and rotate to ON ( I ) position. b. After turning on the transmitter power, check the Status LED on the transmitter for any sign of system irregularities (refer to section 6.10.1 Transmitter Status Indications). If the transmitter is in good working order the Status LED will display constant green for up to 2 seconds at power on (no faults detected). c. d. e. Rotate the power switch key further to the START position and hold it there for up to 2 seconds (Status LED constant green). When the receiver MAIN relays are activated the Status LED will change from constant green to constant orange

(system on). The power switch key will retract back to the ON ( I ) position when let go. The same START position becomes an auxiliary function thereafter (refer to section 4.2.2.3 START + AUX Function). Pressing any pushbutton prior to executing the START command at system startup will result in no signals transmitted (Status LED blinks orange). Now press any pushbutton on the transmitter to begin operation. During transmitter inactivity (pushbuttons not pressed), the transmitter will automatically switch to standby mode, with an orange blink on the Status LED every 4-second interval. Always turn off the transmitter power when not in use to save battery power. In case of an emergency, press down the STOP button to disconnect the receiver MAIN relays (Status LED blinks 3 reds and then shuts off). To resume operation, rotate the STOP button clockwise or counter clockwise, the button will pop up. Then execute the START command to reconnect the receiver MAIN relays. For safety, executing the START command is strictly required every time when the transmitter is turned on or after every STOP button reset. Flex 8ES/EX Standard, AB and Tandem Instruction Manual September 2016 Page 34 of 42 f. g. After 5 or 30 minutes of inactivity (pushbutton not pressed) the receiver MAIN relays are temporarily disconnected (refer to section 4.1.5 Inactivity Timer Settings). The Status LED blinks 3 reds and then shuts off. Press any pushbutton or execute the START command to resume operation (refer to section 4.1.4 Start Function Settings). Turn off the transmitter power by rotating the power switch key counter clockwise to Off ( 0 ) position; it will disconnect the transmitter power and the receiver MAIN relays altogether. Turn it further counter clockwise to release the key. 6.2. Master/Master Tandem Operation (Tandem models) Receiver B A Receiver To gain control of one or both receivers, first rotate the selector switch to either A, B or A+B position and then execute the START command to activate the receiver MAIN relays inside receiver A, receiver B, or both receivers (depending on the selector switch position). In order to gain control of a receiver, the PITCH pushbutton on the other transmitter must be pressed prior to your takeover. For example, in order for transmitter-A to gain control of receiver-B, transmitter-B must first release its control of receiver-B by first rotate the selector switch to B position and then press the PITCH pushbutton for up to 2.0 seconds. This B action releases transmitter-B control of receiver-B. Transmitter-A is then able to take control of receiver-B by first rotate the selector switch to B position and then execute the START command. Make sure the START command is executed 2.0 seconds after transmitter-B presses the PITCH pushbutton (refer to diagram below).

Once the transmitter is locked on to both receivers, rotate the selector switch to either A, B, or A+B position for independent or simultaneous operation. At beginning of each shift prior to turning on the transmitter power, always check if the selector switch is correctly positioned for the intended receiver or receivers. For safety, there is a 2-second grace period followed after executing the PITCH command. What this means is that after PITCH pushbutton is pressed, executing the START command on the other transmitter within this 2-second grace period is ineffective. In order to gain control of the other receiver you must first wait for up to 2 seconds after the other transmitter presses the PITCH pushbutton and then for you to execute the START command thereafter. 6.3. Master/Slave Tandem Operation (Tandem models) a. Receiver Receiver B A To gain control of one or both receivers, first rotate the selector switch to either A, B or A+B position and then execute the START command to activate the receiver MAIN relays inside receiver A, receiver B, or both receivers (depending on the selector switch position). In order to gain control of a receiver, the PITCH pushbutton on the other transmitter must be pressed prior to your takeover. For example, in order for Master transmitter to gain control of the Slave receiver (receiver-B), Slave transmitter must first release control of its receiver (receiver-B) by pressing the PITCH pushbutton for up to 2.0 seconds. This action releases Slave transmitter control of its receiver (receiver-B). Master transmitter is then able to take control of the Slave receiver (receiver-B) by first rotate the selector switch to B position and then execute the START command. Make sure the START command is executed 2.0 seconds after Slave transmitter presses the PITCH pushbutton (refer to diagram below).

Flex 8ES/EX Standard, AB and Tandem Instruction Manual September 2016 Page 37 of 42 6.4. A/B Pushbutton Select Operation Press the A/B pushbutton repeatedly toggles between output relay A, B and A+B respectively. There are 4 different types of Select A/B sequence available (refer to section 4.1.8.2). Standard Output relay A activated at A position, output relay B activated at B position, both output relays activated at A+B position. Reversed logic - Output relay A activated at B position, output relay B activated at A position, both output relays deactivated at A+B position. Refer to section 4.2.4 JP3 jumper settings. 6.5. A/B Rotary Select Operation (AB models) Standard - Rotate to A position activates output relay A, rotate to B position activates output relay B, rotate to A+B position activates both output relays. Reversed logic - Rotate to A position activates output relay B, rotate to B position activates output relay A, rotate to A+B position deactivates both output relays. Refer to section 4.2.4 JP3 jumper setting. 6.6. Pitch & Catch Operation Press the PITCH pushbutton for up to 2 seconds to release control of the receiver. After 2-second grace period, rotate the power switch key to START position for up to 2 seconds to gain control of the receiver. The 2nd operator is unable to take control of the receiver unless the 1st operator presses the PITCH pushbutton. Refer to section 4.2.2.10 and section 4.2.3.2 on how to set to this function. 6.7. Transmitter Access Card (TAC) Operation After turning on the transmitter power, place the TAC directly over the RFID marking located on the backside of the transmitter. A 2-second green on the Status LED represents access card accepted. Status LED with red blinks represents invalid access card. Then rotate the power switch key to the START position for up to 2 seconds to begin operation. TAC is not required after every transmitter inactivity restart, only during initial transmitter power on. Flex 8ES/EX Standard, AB and Tandem Instruction Manual September 2016 Page 38 of 42 6.8. Changing Batteries Changing transmitter batteries (AA alkaline battery x 2) by unscrewing the battery cover located on the backside of the transmitter. During battery installation make sure the batteries are installed correctly, with + to + charge and to charge. Also make sure the screw is tightened after battery installation to avoid water, moisture, dirt, grease, and other liquid penetration. 6.9. Battery Charging The transmitter is designed to accept any off-the-shelf Ni-MH rechargeable batteries. When charging both transmitter and individual batteries at the same time the priority always goes to the transmitter charging. The individual battery charging begins only after the transmitter charging is completed. Depending on the battery capacity the average charging time is approximately 2.5 hours from completely drained to fully charged. Constant red on the LED represents charging in progress, constant green represents batteries fully charged, and LED off represents no batteries detected. Please do not use any rechargeable lithium ion batteries as it will damage both the transmitter and the charging station.
