3 Your VHF in detail
3.1 Abnormal power-down
If for any reason the main power disappears for a period less than 10 minutes, the VHF will
be able to turn itself on when power is resumed (without pressing ON/OFF).
If the VHF was abnormally powered down for less than 1 minute, the VHF will start up with
the same settings as before the power failure took place (communication channel, volume,
squelch settings, etc.).
If the abnormal power down lasted more than 1 minute the VHF might start up with the
settings as they were last time the VHF was turned off normally.
3.2 Settings
All volume settings are stored as default during the power off sequence.
3.3 Automatic squelch programming
It is possible to attach a squelch level with each channel if particular noisy channels require
continuous special squelch setting. If a channel is selected squelch level is inherited from
either the global setting or a stored squelch level for that particular channel (default is that all
channels are using the global squelch level).
Storing squelch level on a channel is done while listening on that particular channel:
• Push the button.
• The squelch level is now automatically adjusted to suppress the noise on the
channel. While adjusting, noise is heard. The squelch level indicator follows adjust-
ment, and finally display the required level. The squelch level is memorized on the
channel, indicated by flashing the SQ LED (flashing 3 seconds).
If a channel with a programmed squelch level is selected and the SQUELCH button is turned
the programmed squelch level for that channel is removed (global level).
During Dual Watch or Scanning only the global squelsh level is used (as indicated by the
squelch level indicator). Channel 16 squelch level is not programmable.
All programmed channel squelch levels are stored during power down and restored during
power-up sequence.
