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.

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
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.
