The error codes are as follows:
ROM-ER Transmitter does not have the initial data so the microphone is completely dead and cannot be programmed. ERROR1 Failure on RF circuitry, frequency cannot be programmed. NO----OR3 Frequency to be programmed into the transmitter exceeds the highest frequency of the designated frequency band of the transmitter. NO----OR4 Frequency to be programmed into the transmitter exceeds the lowest frequency of the designated frequency band of the transmitter.
**Note:
NO----OR3 and NO----OR4 will not change the transmitter's original frequency and the transmitter will still operate normally with the error message on display. To remove the error message from the display panel, please switch off the transmitter and switch it on again. MUTE control enables audio to be muted or un-muted temporarily.

External mute connector is a 3.5mm jack. When an external mute switch cable, MJ-70 (optional) is connected, user can manually mute and un-
mute the audio temporary. External mute connector MJ-70 External Mute Switch (optional) B1 B2 3.5mm jack. External mute switch on/off button. a. When other microphones are in use, some changes may be needed to another microphone before adding it to the system in order to avoid high frequency interference, as illustrated in diagram (1). b. When a high frequency radio wave causes interference, it normally affects the system by generating a persistent noise or by deteriorating the frequency response. In an effort to ameliorate these problems, a 330PF bypass condenser can be added on the cartridge as shown in diagrams (1) and (2). If this method is not possible, another option is to add a bypass condenser on the 4-pin XLR connector as shown in diagrams (3) and (4).
**The Best Method
(1) Connect to two-wire condenser capsule NOTE: Plug in the device before power on the bodypack transmitter. Add 330pF bypass capacitor B1 B2
(2) Connect to three-wire condenser capsule Add 330pF bypass capacitor 22 23 Rechargeable Digital Wideband Bodypack Transmitter Rechargeable Digital Wideband Bodypack Transmitter

Pushing down both snap locks on the sides to open battery compartment cover. Take out the one batteries. (Figure 3) Insert one charged 18500 rechargeable battery into the battery compartment according to the correct polarity (- and +) as shown in (Figure 4)
. Then close the battery compartment cover tightly.
(Figure 3)
(Figure 4) Caution Remove the batteries if unused for a long period of time to prevent battery leakage, corrosion and causes possible damage to electronics. Note: Transmitter cannot be powered on with charged battery. Method 1:
a. Ensure battery is inserted correctly with + top side. b. c. If battery is inserted correctly it could be due to self battery protection mechanism. Insert the transmitter into the charger to re-charge for 10-20 seconds to wake-up the battery. It should work. If charger cannot be used, reverse the battery insertion for 10-20 seconds, wake up the battery with correct polarity. It should work. Method 2:
a. Power off the transmitter before open the hinged cover. Press battery protection circuitry reset button once to wake-up battery. Power on the transmitter.
