OPERATION
3-10
Revised February 1997
Part No. 001-9750-005
If the transceiver is equipped with a MENU
option switch, the Menu Mode can also be selected to
control various functions. The functions that can be
controlled by the Menu Mode are indicated in
Table 3-2 by an “X” in the “MENU ITEM” column.
System operator programming controls which
functions are displayed in the Menu Mode and also
which option switches are available. Therefore, a func-
tion can be fixed by system operator programming by
disabling that menu item, programming the default
condition, and not programming an option switch to
control it. Refer to Section 3.6.5 for more information
on creating a radio profile. If a function is assigned to
an option switch, it is not available as a menu item.
If a call is received or transmitted while in the
Menu Mode, the Menu Mode is exited and any
changes are saved. The menu mode is selected as
follows. The Menu Mode and option switch functions
are described in the following sections.
Selecting The Menu Mode
a. Press the MENU switch to select the Menu Mode.
Then turn the Select switch to select the parameter
to be modified.
b. If the parameter has only on/off choices, the current
status is shown as “ON” or “OF” in the status dis-
play (located between the system and group num-
bers). To change the status, press the Select switch.
c. If the parameter has several choices, the current sta-
tus is displayed by pressing the Select switch and
changed by rotating the switch.
d. The Menu mode is exited and the changes saved by
pressing the MENU switch or if a call is received or
the transmitter keyed. Changes are automatically
saved and the Menu mode exited 2 seconds after
changing a parameter or 10 seconds after no
activity.
3.5.2 A/D (SCAN LIST PROGRAMMING)
The A/D option switch is used to add system/
groups to or delete them from the scan list. Pressing
this switch changes the status of either the displayed
system or group
.
The bar above the number indicates
which is changed.
To move this bar between the
system and group, press the Select switch. An asterisk
in the status display next to the system or group
indicates that it is in the scan list. Refer to Section
3.4.6 for more information.
3.5.3 AUTO-REGISTRATION
This Menu mode feature is indicated by “MN
AUTOREG”, and it is used to turn Multi-Net auto-
registration on and off (see Section 3.7.2).
3.5.4 AUXILIARY 1 AND 2
Up to two auxiliary functions can be turned on
and off by the Menu Mode “AUX 1” and “AUX 2”
parameters or the AUX 1 and AUX 2 option switches.
(There is also a SIREN key cap that can be used for
these switches.) When a switch is used, the on condi-
tion is indicated by a triangle in the display under the
switch. The output lines for these functions come from
optional universal interface connector J601. Auxiliary
1 is pin 14 (AUX 1), and Auxiliary 2 is pin 16
(OUTPUT B). These outputs are active high. Refer to
Section 4.7 for programming information.
An appropriate driver circuit is required to utilize
these outputs. Maximum source current of AUX 1 is
50 mA and the output voltage is 8 VDC
±
10%.
OUTPUT B is a TTL output that can provide approxi-
mately 10 mA of drive current.
3.5.5 BACKLIGHT
The Menu Mode “BACKLIGHT” parameter or
the BKLHT option switch can be used to turn the
display backlight on and off. This light allows the
display and option keys to be seen in low-light condi-
tions. If this feature is not controlled by the Menu
mode or option switch, it is usually programmed
“Enabled” so that it turns on with transceiver power.
3.5.6 BANK SELECT
If banks of systems have been programmed, the
Menu Mode “BANK SELCT” parameter or the
BANK option key is used to enable the bank select
mode. The Select switch is then turned to move to the
desired bank and then pressed to select that bank.
Refer to Section 3.6.6 for more information.
