5. RF GAIN CONTROL:
This control is used to reduce the gain of the RF amplifier
under strong signal conditions.
6. ECHO
CONTROL:
This control is used to adjust echo effect.
7. TIME
CONTROL:
This control is used to adjust intervals of echo.
8. CHANNEL
SELECTOR:
This control is used to select the desired transmit and
receive channel.
9. SWR
LED:
This LED lights red when your SWR is higher than about 3:1. This is
not an exact indicator of 3:1 SWR, but it is an indication that you should check
your SWR reading.
10. FRONT PANEL METER:
The front panel meter allows the user to monitor
signal strength, RF output power, SWR level and AM modulation level.
11. 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.
12. TALKBACK (TB) CONTROL:
Turn clockwise to activate Talkback circuit.
Adjust this knob for desired volume of Talkback. This is used to monitor your own
voice. For example, you could use this feature to compare different microphones.
13. RF POWER CONTROL:
This control allows the user to adjust RF power output.
14. BAND SELECTOR:
This switch is used to select the band.
15. SWR/MOD/PWR SWITCH:
This switch controls the function of the meter
during the transmit mode. In the “SWR” position, the meter indicates the Standing
Wave Ratio (SWR) of your antenna. There are no adjustments because the SWR
circuit in this radio calibrates itself automatically. When the switch is in the
“MOD” position, the green scale on the meter indicates your percentage of
modulation in the AM mode only. It is most accurate when testing at maximum
power output. When this switch is in “PWR” position, the meter indicates your
power output.
16. MODE SWITCH:
This control allows you to select one of the following operating
modes: AM/FM/PA.

17. +10KHz-NB/ANL/ NB/ANL/ OFF SWITCH:
When in the upper position,
transmit and receive frequency is shifted up 10KHz and the Noise Blanker (NB)
and Automatic Noise Limiter (ANL) circuits are activated too. When the switch is
in the middle position, the Noise Blanker (NB) and Automatic Noise Limiter (ANL)
circuits are activated, but the +10KHz circuit is not activated. When in the lower
position none of these circuits are active. The Noise Blanker is very effective in
eliminating repetitive impulse noise such as ignition interference.
18. BRIGHT/MED/DIM SWITCH:
This switch controls the level of brightness for
the meter lamp, faceplate and channel display.
19. ECHO/OFF SWITCH:
This switch is used to turn on the Echo circuit.
20. +10KHz LED:
This LED lights green when the +10KHz function is on.
21. CHANNEL DISPLAY:
The channel display indicates the current selected channel.
22. RX/TX LED:
The red LED indicates the unit is in the transmit mode. The green
LED indicates the unit is in the receive mode.
