Operation
CONTROL FUNCTIONS
FRONT PANEL
1. OFF/ON/VOLUME: Turn clockwise to apply power to the radio and to
set the desired listening level.
2. SQUELCH
CONTROL: This control is used to cut off or eliminate
receiver background noise in the absence of an incoming signal. For
maximum receiver sensitivity it is desired that the control be adjusted
only to the point where the receiver background noise or ambient
backgrounds noise is eliminated. Turn fully counterclockwise then
slowly clockwise until the receiver noise disappears. Any signal to be
received must now be 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 setting.
3. MIC GAIN CONTROL: This control adjusts the microphone gain in
the transmit mode. This feature is designed for use in a high-ambient
noise environment or to maximize talk power.
4. RF GAIN CONTROL: This control is used to reduce the gain of the
RF amplifier under strong signal conditions.
DUAL WATCH: This circuit will “Watch” for activity on any one of the
three fixed channels (6,19 or 21) while you are operating on your normal
frequency. The radio cycles back and forth between the two frequencies and
it will stop cycling as soon as a signal is detected on the channel you are
“watching”. Naturally, you will need to use the Squelch because even noise
will be considered a “signal” and the cycling will stop. This circuit is turned
ON and OFF by pushing the MIC gain knob. Please note that the LED under
the channel display will be green when the Dual-Watch is ON.
5. DIMMER
CONTROL: Dims the meter lamp and all LED readouts. In
the “OFF” position, the meter lamp and all LED readouts are OFF.
6. RF POWER CONTROL:
Adjusts power output in AM and FM
transmission.
7. ECHO AND E/VC CONTROL:
ECHO: To use the ECHO, switch 15 must be in “ECHO” and the
switch on this pot must be ON, both the inner and outer controls
adjust the ECHO SOUND.
VOICE CHANGER:
The voice changer changes the pitch of your
voice. When the outer pot is turned counterclockwise, your voice will
sound lower. When this pot is turned clockwise, your voice will sound
higher. The inner pot and the switch on the inner pot do not affect the
voice changer. VC is turned ON at switch 15.
ROBOT:
There are four different robot sounds. They are turned ON
using switch 15. They are not adjustable and this pot does not affect
the robot sound in any way.
TALKBACK:
This radio has a talkback circuit in order to monitor
the sound affects (Echo, voice, changer, robot). There is a switch on
the back of the microphone to turn the talkback circuit ON or OFF.
8. SWR CAL CONTROL:
Normally this switch is set to “PO”. Then,
during transmission, the meter indicates output power. To read SWR,
rotate this knob during transmission until the needle moves to the “SET”
point on the SWR scale. Then, while still transmitting, set the R.B./SWR
switch to SWR.
9. CLARIFIER CONTROL:
Allows for
±
5 KHz adjustment of the
channel frequency.
