Transmitter Thermal Foldback
If the transmitter temperature increases to the point where
damage to the transceiver could result, power is automatically cut
back. When this happens, the transmit indicator on the front panel is
orange instead of red when the transmitter is keyed. After sufficient
cooling occurs, power output automatically returns to the normal
level and the indicator changes back to red. One time when this indi-
cation could occur is if you transmit for an extended period.
STANDARD GROUP CALLS
General
Most calls you make are probably the standard group type
described in this section. These calls are between you and another
mobile or control station. The main difference between these calls
and the other types that can be placed is that no number is dialed
using a keypad. The following procedure applies to all three types of
operation (LTR-Net, LTR, and conventional).
Placing a Standard Group Call
1. Turn transceiver power on and set the volume as described starting
on page 15. With conventional operation, also make sure that the
squelch is properly set as described on page 18.
2. Select the system and group of the mobile being called as
described starting on page 17.
3. If a conventional call is being placed, monitor the channel
manually or automatically as described on page 44.
