Squelch level setting
A squelch eliminates white-noise during the stand-by state (the
background noise when a signal is not received).
Higher level settings will keep the squelch “closed” more tightly for
quieter monitoring, but weak signals will not be heard. Lower settings
allow weaker signals to “open” the squelch but noise may also cause it
to open.
1.
Press
SQL
key. icon appears on the display and the squelch
level will be shown at the position where the memory number is
displayed.
16 levels, between 0 - 15, are available. “0” is the lowest setting.
2.
By rotating the dial or by using the [UP]/[DOWN] keys on the
microphone, adjust the squelch to the desired level. To return to
normal use, press [PTT] or any key on the front panel; or if there
are no operations within 5 seconds, the unit will store the setting
and will return to its original status.
Proper squelch level:
In the adjusting procedure, set it to level zero to hear the noise
first, then turn the dial to increase the level. When a noise
disappears at level 03 for example, select level 04~05 to set as
the squelch level.
