5. MODE SWITCH: This switch allows you to select one of three
following operating modes: PA/FM/AM.
6. Fr. POOL: The Frequency Pool allow the user to select the desired
segments of frequencies.
7. ECHO/TIME CONTROL: The ECHO control is used for echo effect. The
TIME control is used to control the intervals of the echo sound.
8. RF POWER CONTROL: This control enables adjustment of RF power
output continuously up to the rated output power.
9. TALKBACK/OFF CONTROL: Adjust this knob for desired volume of
Talkback. This is used to monitor your own voice. Or example, you
could use this feature to compare different microphones.
10. CHANNEL SELECTOR: This control is used to select a desired
transmit and receive channel.
11. FRONT PANEL METER: The front panel meter allows the user to
monitor signal strength and RF power out level.
12. TX/RX LED: The red LED indicates the radio is in the transmit mode.
The green indicates the radio is in the receive mode.
13. FREQUENCY COUNTER: This frequency counter indicates the
transmit frequency digitally.
14. DIM/BRT SWITCH: This switch is used to adjust the brightness of the
meter and LED display for optimum intensity for day or nighttime
driving.
15. HI/LOW TONE SWITCH: This switch changes tone quality in receive
only. In LO position, bass is increased and in HI position, treble is
increased.
16. S-RF/SWR SWITCH: In the S-RF position, the meter swings
proportionally to the strength of the received signal. When transmitting,
the meter indicates relative RF output power. When in the SWR

position, the Standing Wave Ratio (SWR) of your antenna. There are no
adjustments because the SWR circuit this radio calibrates itself
automatically.
17. NB/ANL 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.
18. ROGER BEEP SWITCH: When this switch is placed in the ROGER
BEEP position, the radio automatically transmits an audio tone at the
end of your transmission. This indicates the end of your transmission
so that people who are having trouble hearing you will know that you
are done speaking. As a courtesy to others, use the Roger Beep only
when necessary.
19. +10KHz SWITCH: In the +10KHz position, the transmit and receive
frequency is shifted 10KHz up.
20. CHANNEL DISPLAY: The channel display indicates the current
selected channel.
