4.2 RECEPTION
1. Turn the POWER SWITCH/VOLUME CONTROL knob clockwise to
turn the transceiver on.
2. Press the SQL key, then press (Down) key until squelch level is
minimum. This state is known as squelch off.
3. Select a channel that has no signal being received (no one is
transmitting on the channel) and only noise is heard.
4. Turn up the POWER SWITCH/VOLUME CONTROL knob until the
noise or audio from the speaker is at a desired level.
5. Press the SQL key, then press the
(Up) key and stop immediately
after the noise disappears. This condition is known as the Squelch
Threshold. If the
(Up) key is pressed beyond this level, weak
signals may not be received. No signal can be heard until a signal is
received that exceeds the squelch threshold. The SQUELCH
ADJUSTMENT mode will automatically turn off in about 5 seconds. To
turn off the SQUELCH ADJUSTMENT mode immediately, press the
SQL key.
6. To change channels, press the
(Up) or (Down) key. Sometimes,
a slight adjustment of the squelch threshold is needed as some
channels have a higher noise level than others.
Please refer to the Owners Manual Supplement for a complete listing
of all USA, International and Canadian VHF Marine channels and their
use.
7. If necessary, press the
(Lamp/key lock) key to turn on the lamp.
The lamp automatically turns off in about 5 seconds. To turn off the
lamp sooner, press the (Lamp/key lock) key again.
8. To lock the channel in the operating mode so that it is not accidentally
changed, hold down the (Lamp/key lock) key for about 1 second.
This locks the UP and DOWN keys and all front panel controls except
the H/L, PTT and
(Lamp/key lock) keys. The key lock symbol
appears on the display to indicate that the channel is locked.
Hold down the
(Lamp/key lock) key for about 1 second to unlock
the channel. The key lock symbol
disappears from display.
