slightly stronger than the average received 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 a maximum
clockwise squelch setting .
6. RF GAIN CONTROL : This control is used to reduce the receiver's front-
end gain when receiving strong signals.
7. CLARIFIER CONTROL : This CLARIFIER is used to fine tune the
received signal for the maximum clarity in SSB or CW mode. It can adjust
the receive frequency ±500Hz but does not affect the transmit frequency
or the frequency display.
8. MODE SWITCH : This switch allows you to select one of the following six
operating modes : FM, AM, USB, LSB, CW and PA.
9. NB/ANL BUTTON (NB/ANL) : The noise blanker (NB) is very effective in
eliminating repetitive impulse noise such as ignition interference. In the
ANL position, the AUTOMATIC NOISE LIMITER within the audio circuits
is activated .
10. ROGER BEEP BUTTON (R.BEEEP) : This button activates the ROGER
BEEP circuit when it's function is selected.
11. SPLIT BUTTON (SPLIT) : This control enables the offsetting of an
operating frequency for FM repeater operation.
12. PROGRAM BUTTON (PRG) : This button is used to program operating
or scanning frequency into memory.
13. MANUAL BUTTON (MAN) : This is used to return the unit to manual
mode.
14. SHIFT BUTTON (SHF) : The button selects frequency steps in 100 Hz,

16. SWR BUTTON (SWR) : This control is used to check SWR.
17. SCAN BUTTON (SCAN) : This is used to scan frequency in each band
segment.
18. MEMORY BUTTON (MEM) : This button is used to program memory
channel.
19. ENTER BUTTON (ENT) : This is used to program frequencies in
memory.
20. LOCK BUTTON (LOCK) : Pressing this button enables a lock on a
selected frequency ,disabling the Frequency Selector Control, UP /
DOWN buttons on the front control panel, or remote UP/DOWN buttons
on the microphone. Repressing the switch will unlock the frequency.
