5. CLARIFIER: The clarifier is normally set to the center position. This feature
has several uses and can greatly enhance receiver operation. If a receive signal is
slightly off frequency, th is control can be operated to optimize the receive
signal. This control is primarily intended to tune in SSB signals, but, it may be
also used to optimize the AM signal.
6. MIKE GAIN: This control is used to adjust, as required, microphone input
sensitivity for optimum amount of modulation in transmit. UNIDEN's marine
band transceivers have been designed to permit the user to attain levels of
modulation up to 100% depending on the setting of the microphone gain con-
trol, using the microphone provided with the unit. UNIDEN's automatic
compression and peak limiting circuits assure maximum modulation with
minimum distortion.
7. DUAL WATCH BUTTON: Provides for automatic monitoring of channel 88.
Push "DUAL" button and the watch is set. Now select any other legal channel
and every second the receiver will leave the main channel and sample activity on
Channel 88. If activity is found, receiver will remain on Channel 88 until
message is complete. Channel 88 thus has priority over the main channel. To
disable the watch function, push "DUAL" Button. Whilst in DUAL position.
please note that transmitter is not available to transmit, push CH88 switch.
8. CH88 SWITCH: This switch is for use when emerg~ncy communication is
needed on the emergency channel, CH88, Pressing the CH88 switch activates
CH88 regardless of the position of the channel selector switch. When CH88
switch is pressed, the channel display is blanked and the CH88 indicator is
activated.
9. PA-TX/RX SWITCH: This control engages the PA function. The PA function
should not be used unless an external speaker is connected. In the TX/RX
position, the PA function is disabled and the radio will transmit and receive on
the selected channel.
10. NB/ANL SWITCH: When the switch is placed in the NB/ANL position, both RF
Noise Blanker and Automatic Noise Limiter circuits are activated. The NB is
very effective for repetitive impulse noise such as ignition noise. The ANL
reduces annoying hash-type noises.
11. RF GAIN: This control is used primarily to optimize reception in strong signal
areas.Gain is reduced by counterclockwise rotation of the control.
INDICATOR FUNCTION
1. S/RF METER: This meter displays relative transmitter RF output power when
transmitting, and input signal strength when receiving.The meter is illuminated
when power is on.
