RECEIVING TRANSMISSIONS
Follow these steps to receive standard transmissions.
1. With the radio on, rotate
SQ
counterclockwise until you hear
a hissing sound. Then slowly rotate
SQ
clockwise just until
the noise stops.
Notes:
BUSY
appears when the HTX-400 receives a standard
transmission or if the squelch is open. If the transmission
uses CTCSS tones,
CALL
also appears.
Volume, power, and squelch are combined in one control.
The inner control is
VOL
(volume) and power on/off, while
the outer control is
SQ
(squelch).
If the HTX-400 picks up unwanted, weak transmissions,
rotate
SQ
clockwise to prevent the squelch from opening
for these transmissions. If you want to hear weak trans-
missions, rotate
SQ
counterclockwise. When you do this,
you might hear hissing between transmissions.
2. Set
VOL/OFF
to a comfortable listening level.
TEMPORARILY OPENING SQUELCH
If you use the Tone Squelch (CTCSS) feature, you might not hear
a trans
mission on the current frequency. T
o temporarily open the
squelch so you can hear all transmissions on the frequency, hold
down
MO
. To resume normal operation, release
MO
.
