Cobra 25wxst Mode D’Emploi

9

This switch selects any one of forty

Citizens Band channels desired. The selected channel is indicated by the
LED readout, directly above the channel selector knob.

Swings proportionally to the strength of the incoming signal

during receiving. 
RF-METER. 

Swings proportionally to the RF output power while 

transmitting. 

Selects the mode of operation. In the CB-ANL po-

sition, the PA function is disabled and the unit will transmit and receive
on the selected frequency. The PA function should not be used unless a PA
speaker is connected. In the PA mode, incoming CB transmissions will be
heard through the PA speaker. This allows you to monitor messages when
you are not inside your vehicle. NOTE: ANL (Automatic Noise Limiter)
is a non-switchable feature that is always on to reduce background noise.

When this switch is in the NB position, the RF 

noise blanker is activated. The RF noise blanker is very effective for repet-
itive impulse noise, such as ignition interference.

Used for selection between receiving Weatherband

broadcasts or normal CB operation. The radio will not transmit in the
Weatherband mode.

Used for instant selection of emer-

gency Channel 9 (CH. 9 position) or information Channel 19. In 
NORMAL position, all 40 CB channels can be accessed by the CHANNEL
SELECTOR switch (9).

When your radio is in the CB receive

mode, the LED will be green. When in transmit mode, the LED will be red
and in Weatherband mode, the LED will be orange.

A red LED will illuminate when the

SoundTracker system is engaged on your CB.

Depressing this button turns on the

SoundTracker system in your CB.

The selected channel will be displayed.

Display will be off when radio is in Weatherband mode.

Refer to controls, indicators and connectors as illustrated below:

Front panel microphone connector.

Turn clockwise to turn power on and set the desired

listening volume.

This control is used to cut off or eliminate receiver back-

ground 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 background noise is 
eliminated. Adjust until the receiver noise disappears. This will require
the incoming signal to be slightly stronger than the average receiver
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.

Adjusts the microphone gain in the transmit and PA

modes. This controls the gain to the extent that full talk power is available
several inches away from the microphone. In the Public Address (PA)
mode, the control functions as the volume control.

This switch selects any one of the

seven U.S. NOAA Weatherband broadcast stations (see p. 1). Always keep
set to local NOAA Frequency. NOTE: The Weather Alert Tone can be com-
pletely turned off by positioning this selector in the off location.
