GENERAL OPERATION
15
- Indicates that an option controlled by the AUX switch or
OPTION menu parameter is enabled (see page 24).
- Indicates that a call has been received on a group programmed
for a call indicator (see page 21). To turn this indication off, press
any key.
- Indicates that the monitor mode is enabled. This mode disables
Call Guard squelch and other squelch control features so that all
messages are heard on conventional systems (see page 44).
GENERAL OPERATION
Power-Up Sequence
When power is turned on, the backlight turns on, all segments
in the display are momentarily enabled, and the last seven digits of
the transceiver part number are very briefly displayed. A beep then
sounds (if tones are enabled) and the transceiver is operational.
Determining Volume Level
The relative volume setting can be determined by noting the
position of the index on the volume knob. You may also be able to
enable a reference tone or background noise for use in setting the
volume. Proceed as follows:
If key press tones are enabled, a short tone sounds when an option
switch is pressed or the Select switch is pressed or rotated.
If a conventional system is selected, take the microphone off-hook
and if someone is using the channel, voice is heard. If no one is
using the channel, the squelch control can be adjusted counter-
clockwise as described in “Setting Squelch Control” on page 18
and noise is heard. It is not possible to unsquelch the transceiver
in this manner when an LTR-Net or LTR system is selected.
