8. RX INDICATOR: Lights during the receive mode whenever a station is being re-
ceived, or whenever the SQUELCH control is adjusted fully counter clockwise.
9. GROUP SCAN INDICATOR: Lights when the GROUP SCAN mode is selected.
10. MEMORY INDICATOR:
In the normal mode (SCAN switch OUT): lights if the channel indicated by the CHAN-
NEL INDICATOR and selected by the CHANNEL SELECTOR switch is programmed
into the selected scan memory.
11. OPEN SCAN INDICATOR: Lights when the OPEN SCAN mode is selected.
12. CHANNEL INDICATOR: LED indicates the channel number in use.
During NORMAL Mode: Displays the channel selected by the CHANNEL SELEC-
TOR Switch.
During SCAN Mode: Displays the channel currently being scanned. Channel num-
ber changes every 0.07 second.
13. FRONT MICROPHONE SOCKET
14. OFF/VOLUME CONTROL: Turn clockwise to apply power to the radio and to set the
audio volume to the desired listening level. Turn fully counterclockwise to turn the
radio OFF.
15. SQUELCH CONTROL: This SQUELCH Control is rotated to cut off or eliminates
received background noise in the absence of an incoming signal. For maximum re-
ceiva sensitivity, it is desired that the control be rotated only to this point where the re-
ceive background noise or ambient background noise is eliminated. Turn the control
fully counterclockwise, then slowly rotate clockwise until the receive noise disap-
pears. Any signal to be heard must now be slightly stronger than the average re-
ceived noise. Further clockwise rotation will increase the threshold level which a
signal must overcome in order to be heard. Only strong signals will be heard at the
maximum clockwise setting.
16. MEMORY SWITCH:
In the NORMAL mode: Press the MEM switch to program or disable channels in the
selected scan memory.
In the GROUP SCAN mode: When scanning, press the MEM switch to HOLD the
channel currently being scanned. Press again to resume scanning.
In the OPEN SCAN mode: When scanning, press the MEM switch to SKIP over a
busy channel you do not wish to listen to.
17. DUPLEX SWITCH: To program semi-duplex operation for channel 1 through chan-
nel8. Select the channel you would like to use as repeater channel (check your local
repeater station frequency first) and push the DUP switch and then DUP indicator will
turn on. Select next repeater channel and push the DUP switch again and so on. To
put the channel back to normal simplex operation, just select the DUPLEX pro-
grammed channel by channel selector and push the switch so that the DUP indicator
turns off to indicate that channel is no longer repeater frequency off-set channel. CH
1 through CH 8 are programmable for the repeater operation.
