SYSTEM PROGRAMMING/OPERATION The FMR-500/RE-2 System uses the same basic programming steps in the Receiver and Transmitters. Learning these basic steps early will save time and effort. Read the following section then proceed to the Set-Up Section. Receiver:
Note: The FMR-500/RE-2 receiver is supplied with a Secure or lockout function. All of the buttons can be secured to prevent accidental operation or tampering. If the Set switch is pressed in Secure Mode, Loc-Out will appear on the screen. If the Up or Dow buttons are pressed in Secure Mode, nothing happens. Pressing the power button in Secure Mode will not turn the receiver off. To unlock the buttons, Press and Hold the Up and Down buttons for 3 seconds. ACC.ESS will appear as long as the buttons are held. To re-lock the receiver, press the Up and Down buttons for 3 seconds until Sec.uRE is displayed. FMR-500/RE-2 System POWER: The Power ON/OFF button is located near the upper left corner Page 5 of the display screen. Press the button once to apply power, press again to remove power. Removing power from any unit saves the last operation of all screens. Some circuitry will remain active even though power is OFF. SCREEN: When power is applied, the display screen will show the following:
A. Group (GP), Channel (CH) and Frequency that the unit is set to.
(factory default setting or where last used). B. Voice or Guitar Mode. Normal default is set to Voice. If in Guitar Mode, a small guitar symbol will be shown on the display (between Frequency and RF). If the guitar symbol is absent, the unit is set to voice mode. C. Diversity Antenna Symbols. A small antenna symbol will be shown in between CH and AF. One of two symbols will be on or flickering between symbols, indicating diversity operation. (transmitter or user must be moving (normally) before diversity action can be seen). D. Battery Symbol. A small battery symbol will be shown below the Antenna symbol. The symbol will be dark for full battery and light
(proportional) indicating battery strength. E. Clear Scan symbol. When the receiver is in Clear Scan mode, the symbol will be flashing. Screen Options:
To change to Guitar operation :
Press the Power Off button. Hold the SET button IN then press the Power On button. The Guitar Symbol should now be shown on the display. To go back to Voice operation, Press Power OFF, hold the Set button in and Press Power On. To select a Special Frequency:
(Other than the pre-programmed Group/Channel/Frequency), press both the Set and Up buttons at the same time. The Group and Channel will display dashes (). Press SET and the frequency display will flash. Press and release the Up button one time to increase the frequency by 25 KHz. Press and release the Down button one time to decrease the frequency by 25 KHz. If either the Up or Down button is held In for approximately 5 seconds, the frequency change will enter Page 6 FMR-500/RE-2 System Screen options contd fast mode to change frequencies quickly. Release the button to stop the fast change. Some practice is required to stop the frequency scan near the desired frequency. The final frequency can be selected by quickly tapping the Up or Down button to get to the frequency desired. Once the final frequency is selected, press the Set button once to save the frequency. To return to Group/Channel mode, press both the Set and the Up buttons at the same time. To change the Squelch Level :
(Other than the factory setting), press and hold the UP button for 3 seconds. The Squelch screen can now be seen. CAUTION!!! Setting the squelch level to 0 opens (disables) the Squelch which will allow LOUD noise to be heard on the audio system!! Turn the audio volume down before proceeding!
Lower values of squelch (1-5) enable weaker signals to be heard that may include weak interference. Higher values of squelch (5-9) prevent weak interference from being heard but also shorten the operating range
(distance) and may increase the risk of noise-ups or drop-outs. Once the desired squelch value is selected, press the SET button to save the setting. Note: If any display item is flashing, the Power Off button will not operate. Press Set to save all items before power off. FMR-500/RE-2 System Screen options contd Page 7 SET: The SET button is located near the lower left corner of the display screen. If the display is in the factory ship default mode, pressing this button or key once will cause the GP, Group to flash. Pressing the SET button while GP is flashing will stop the GP flashing and initiate flashing of the CH, Channel . To change the Group or Channel, which ever is flashing, press the UParrow or DOWNarrow buttons located at the upper right and lower right corners of the display, respectively. Continue pressing the up or down buttons to select the desired Group and Channel. The SET button must be pressed after a Channel or Group is selected to save the new Group or Channel.
