for a system within range. If enabled, the system search mode is automat-
ically entered when the PTT switch is released. This mode is indicated by
a short tone and “SYS SRCH” on the bottom line of the display as shown
in the following illustration.
The transceiver then attempts to access, in succession, other systems
that have a group programmed for telephone calls. As each system is
accessed, a beep sounds. If a system is successfully accessed, the new
system/group is selected and a dial tone sounds. The telephone call must
then be placed within a few seconds or normal operation resumes. If no
system could be accessed, the intercept tone sounds, “NO PHONE” is
displayed, the system/group does not change, and the feature deactivates.
This mode can also be canceled at any time by pressing any front
panel option switch. If the menu mode SYS SRCH parameter is select-
able (see page30), this feature can be turned on and off. Otherwise, it is
either enabled or disabled on all LTR systems by programming.

service. To be available, it must be prog rammed in the t ransc eiver you a re
calling. Each selectable LTR group can be progr ammed for thi s fea ture. If
a call is received on one of these groups, the transceiver automatically
transmits a response. This causes the transceiver placing the call to
briefly unsquelch and the call indicator to turn on (i f it is programmed on
the selected group).
