GENERAL OPERATION
Power-Up Sequence
When power is turned on, all segments and indicators in the display
are momentarily enabled, a beep sounds (if tones are enabled), and the
transceiver is ready for service.
Determining Volume Level
The relative volume setting may be determined by enabling a refer-
ence tone using one of the following methods:
•
If key press tones are enabled, a short tone sounds when front panel
keys are pressed.
•
If a conventional channel is selected, take the microphone off-hook and
if someone is talking, audio is heard. If no one is talking, the squelch
control can be adjusted as described in “Setting Squelch Level” on
page 14 and noise should be heard. When an LTR channel (system) is
selected, the receiver cannot be manually unsquelched.
Channel Select and Display
Channels are selected by pressing the CHL up/down switches. The
channel number displayed is actually one of up to sixteen system/group
combinations that can be programmed. If the selected system/group is
programmed for LTR operation, an encode and decode ID code and other
information are selected, and if it is programmed for conventional opera-
tion, a specific radio channel is selected. Refer to page 29 for more infor-
mation on LTR and conventional operation.
Setting Squelch Level
NOTE: This adjustment sets the squelch level for conventional channels
only. With LTR channels (systems), the squelch level is preset and this
adjustment has no effect.
