5. SQUELCH: This knob is used to eliminate background noise being heard through
the receiver, which can be disturbing when no transmissions are being heard
through the receiver. To use this feature, turn the knob fully counterclockwise and
then turn clockwise slowly until the background noise is just eliminated. Further
clockwise rotation will increase the threshold level that a signal must overcome in
order to be heard. Only strong signals will be heard at a maximum clockwise
setting.
6. MIC GAIN: Adjusts the microphone gain in transmit and PA modes. This controls
the gain to the extent that full talk power is available several inches away from the
microphone. In the Public Address (PA) mode, the control functions as the volume
control.
7. RF GAIN: Adjust this knob for desired level of incoming signal.
8. DIM: This knob controls the level of brightness for the meter lamp, faceplate,
frequency display and channel display. Turn clockwise to activate backlight circuit.
9. PWR: This control allows the user to adjust RF power output.
10. ECHO: This control is used to adjust echo effect.
11. TIME: This control is used to adjust intervals of echo.
12. FINE / COARSE: Allows variation of the radio operating frequencies above and
below the channel frequency. Although this control is intended primarily to tune in
SSB signals, it may be used to optimize AM signals.
13. CHANNEL SELECTOR: This control is used to select the desired transmit and
receive channel.
14. FRONT PANEL METER: The front panel meter allows the user to monitor
incoming signal strength, RF output power and SWR level.
15. ILLUMINATED FACE PLATE: All faceplate lettering will fully illuminate to
allow the user easy viewing at night. This unique, solid state, backlight is designed
to maximize night vision while minimizing eye fatigue. Therefore, it is ideal for
switch and control recognition day or night.
16. BAND SELECTOR: This switch is used to select the band.

17. PWR/SWR/RB SWITCH: When in the RB position, the radio transmits an audio
tone at the end of your transmission to indicate that transmission has ended. As a
courtesy to others, use the Roger Beep only when necessary. When the switch is in
the "SWR" position, the meter indicates the Standing Wave Ratio (SWR) of your
antenna (accurate at maximum power output). No adjustments are required because
the SWR circuit in this radio calibrates itself automatically. The SWR readings are
most accurate at full power setting. When this switch is in "PWR" position, the
meter indicates your power output.
18. TALKBACK: This feature is used to monitor your own voice. For example, you
could use this feature to compare different microphones. This knob controls the
volume of the Talkback level. The Talkback circuit is off when the MIC GAIN
knob is depressed.
19. OFF/ NB/ANL /FD.OFF SWITCH: In the NB/ANL position, the RF Noise
Blanker and the automatic Noise Limiter in the audio circuits are also activated.
The Noise Blanker is very effective in eliminating repetitive impulse noise such as
ignition interference. When the switch is in the F.D.OFF position, the frequency
Display is OFF.
20. OFF/ECHO/VC SWITCH: With the switch in VC position you can adjust the
tone and pitch of your voice. With the switch in ECHO you can add echo and
reverb to your voice. In the OFF position your voice will sound natural.
21. FREQUENCY COUNTER: This display indicates the frequency of the selected
channel.
22. OFF/+10K/PA SWITCH: When the switch is in the +10KHz position, the
frequency is shifted up 10KHz. In the PA position, the radio acts as public address
amplifier. Your voice will come out of the speaker that is plugged into the PA. SP.
jack on the rear panel. The radio does not operate when you are in the PA mode.
23. CHANNEL DISPLAY: The channel display indicates the current selected channel.
