2.5.2 TELEPHONE KEYPAD MODELS
General
With the telephone keypad models, both the quick
select switch and the SYS and GRP keys can be used
to select systems and groups (see Section 2.3.3). The
switch can be used as a “quick select” and the keys can
be used for scrolling. Therefore, the selected system/
group may not be the one programmed for the current
quick select switch position. If the quick select switch
is turned while transmitting, the system/group does not
change until the PTT switch is released. The system/
group also does not change if a position has not been
programmed or is programmed with an invalid system/
group.
Each quick select switch position can be locked
by programming. When a locked position is selected,
is displayed and the SYS and GRP keys are
disabled. This ensures that the system/group
programmed for a position is always selected. This is
especially useful when the display cannot be viewed,
such as when carrying the transceiver on a belt. In
addition, locked positions cannot be reprogrammed by
the user. Refer to the following for more information.
Programming Quick Select Switch
If the transceiver is equipped with the telephone
keypad, any quick select switch position not locked by
programming can be reprogrammed from the front
panel as follows:
1. Set the quick select switch to the position to be
programmed.
2. Select the system/group for that position by pressing
the SYS and GRP keys. If these keys do not func-
tion, the switch position or the keypad is probably
locked.
3. Press FCN STR to program the position. If
“ LOCKED ” is displayed and a beep sounds, the
switch position is locked and cannot be
reprogrammed.
2.5.3 OPERATION WITH A LOCKED POSITION
SELECTED (ALL MODELS)
LTR-Net roaming (see Section 2.10.3) is not
disabled when a locked position is selected. Therefore,
if roaming to another locality occurs, the displayed
system can change even if the position is locked.
When scanning is enabled with a locked position
selected, the “Last Selected” configuration described
in Section 2.8.7 is always automatically selected even
if the “temporary” configuration is programmed. If
this did not occur, a transmission could occur on some
system/group other than the selected. This affects
operation only if the PTT switch is pressed with scan-
ning halted.
If an LTR-Net or LTR fixed priority call is
received with a locked position selected, the trans-
ceiver may switch to another group as described in
Section 2.9.1. However, the transceiver stays on that
system/group only until the PTT switch is pressed,
scanning resumes (if applicable), or the system/group
is changed manually.
2.6 MENU MODE
The menu mode can be used to select the
following functions:
•
Power output level
•
Keypad lock and key press tone disable
•
Proceed (clear-to-talk) tone on/off and level
•
Display current software version number
To use the menu mode, proceed as follows:
1. To select the menu mode, press FCN button on the
side and then the MENU key. If the menu mode is
selected while receiving a call, the call is inter-
rupted.
2. Press the key to display the desired parameter
group from the three which follow. The currently
selected parameter in each group is displayed. Press
the PTT switch to select some other parameter.
3. To save the displayed configuration of each group
and resume normal operation, press FCN. This also
occurs automatically if no key is pressed for
3 seconds.
