BASIC OPERATION
Power-Up Sequence
When power is turned on using the top panel on-off/volume control,
the backlight turns on, all segments and icons in the display are momen-
tarily 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.
Backlight Operation
The display and keypad backlight automatically turns on for 3
seconds whenever power is turned on or any key is pressed. If the Back-
light menu parameter is available (see page 35), selecting “On” enables
this operation and selecting “Off” disables the backlight entirely.
Setting Volume Levels
The relative volume level can be determined by noting the position
of the index on the volume knob. You may also be able to enable a tone
or background noise for use in setting the volume as follows:
• If key press tones are enabled, a short tone sounds whenever any key is
pressed.
• If a conventional system is selected and the monitor option switch is
programmed (see page 49), press this switch and if someone is talking
on the channel, voice is heard. If no one is talking, the squelch can be
adjusted as described on page 48 and noise is heard. It is not possible to
manually unsquelch the transceiver when an LTR-Net or LTR system
is selected.
System/Group Display Mode

format and the other is an alpha tag format. To switch between these
