6. BASIC OPERATION
6.1 INITIAL SETUP
1. Install the battery pack on the transceiver (see section “4.1.3 BATTERY
INSTALLATION/REMOVAL”).
2. Install the antenna onto the transceiver.
NOTE: Water resistance of the transceiver is assured only when the bat-
tery pack and antenna are attached to the transceiver and MIC/SP rub-
ber cap is installed in the MIC/SP jack.
6.2 RECEPTION
1. Press and hold in the POWER switch for two seconds to turn the trans-
ceiver on.
2. Press the SQL switch, then press the [T] key until
the SQL level is 00. This state is known as
“Squelch Off.”
3. Turn up the VOLUME CONTROL knob until the noise or audio from the
speaker is at a comfortable level.
4. Press the [S] or [T] key to select a channel or frequency that has no
signal being received (no one is transmitting on the channel) and where
only noise is heard.
5. Press the SQL switch, then press the [S] key and stop immediately after
the noise disappears. This condition is known as the “Squelch Thresh-
old.” If the squelch is set to a higher level, weak signals may not be
received. No noise or no signal is heard until a signal is received that
exceeds the squelch threshold. Sometimes, a slight adjustment of the
squelch threshold is needed, as some channels have a higher noise level
than others.
NOTE: To quickly open the squelch and monitor a channel before trans-
mitting, press and hold this key for 3 seconds.
6. Press the [SCAN] key momentarily to channel the scanning. Refer to
section 7.2 for programming channels into scan memory.
7. Please refer to section 12 for VHF Marine channel assignments.
8. The LCD and keypad are illuminated for 5 seconds when any key is
pressed. The lamp automatically turns off in about 5 seconds.
9. To “lock” the channel so that it is not accidentally changed, hold down the
[H/L] key for about one second. This locks the [S] and [T] keys and all
the front panel controls except the [H/L], PTT and SQL keys. The “
”
symbol will appear on the display to indicate that the keypad is locked.
