GME GX294 - Manual (Page 5)

■ Volume On/Off Control. Rotate the
Volume control clockwise past the click to
turn the GX294 ON. Adjust the volume
control for a comfortable listening level.
■ Squelch Control. The squelch control is
used to eliminate any annoying
background noise when there are no
signals present. To adjust the squelch,
first rotate it fully counter-clockwise until
the background noise is heard. Then
advance the squelch control clockwise
until the noise just disappears. The
receiver will now remain quiet as long as
there are no signals present, but an
incoming signal will override the squelch
and be heard in the speaker. As the
control is advanced further clockwise, the
squelch action is progressively increased
and stronger incoming signals are needed
to override it. To receive extremely weak
signals or to disable the squelch, simply
turn the control fully counter-clockwise.
■ Channel Selector. Select the required
channel by rotating the channel selector
clockwise or counter-clockwise. The
selected channel is displayed on the LED
channel display. Note that if full strength
sunlight is falling on the channel display it
may be hard to see. In this case refer to
the numbers around the channel selector
knob.
■ ISC Switch. The ISC switch activates an
extremely effective Interference
Suppression Circuit (Noise Blanker). When
selected, the ISC combines with a built in
Automatic Noise Limiter (ANL) to almost
totally eliminate electrical impulse
interference, allowing clear reception of
weak signals even under the noisiest
electrical conditions.
When the ISC switch is selected, the Red
LED indicator above it lights.
■ Channel 88 Switch. The channel 88
switch allows instant selection of the
Distress and Calling frequency 27.88 MHz.
When selected, 88 appears in the channel
display and the red Channel 88 LED above
the button lights. Pressing the 88 switch
again, returns the GX294 to the last
selected channel.
The channel 88 switch can be used to
provide instant switching between the
calling channel (88) and your local club
channel as follows:
1. Select your club channel by rotating the
channel selector switch (e.g. channel 94).
2. Press the 88 button in. Channel 88 will
be displayed and the red channel 88 LED
will light.
