3.5 GENERAL FEATURES
3.5.1 AUX (AUXILIARY) SWITCH(ES)
Low Tier Models
The front panel AUX1 and AUX2 switches can
each be programmed to control one of the features
listed below. The other two option switches have fixed
functions (SCAN and A/D) or are disabled by
programming. When the function controlled by AUX1
is enabled, the upper decimal point is lighted, and
when the function controlled by AUX2 is enabled, the
lower decimal point is lighted.
• Encryption (see Section 3.5.7)
• Home system/group (see Section 3.5.9)
• Horn Alert (see Section 3.5.10)
• Monitor (see Section 3.9.1)
• Option, dealer-installed (see Section 3.6.16)
• Priority channel sampling (see Section 3.9.6)
• Squelch adjust (see Section 3.4.6)
• Talk-around (see Section 3.9.4)
High Tier Models
All five front panel option switches are program-
mable for any of the available functions. Any switch
can also be disabled if desired. Refer to Section 3.6 for
more information.
3.5.2 BANK SELECT (HIGH TIER ONLY)
Up to sixteen banks can be programmed with
high tier models. With low tier models, only one bank
can be programmed, so multiple bank select is not
available. Banks are collections of systems that have
been set up by programming. For example, one bank
could be programmed for operation in Minneapolis
and another for operation in Milwaukee. Each bank is
identified by a unique alpha tag.
Banks are selected by the BANK menu parameter
(see Section 3.6.2). Rotate the Select switch to display
“BANK SEL” on the top line, and then press the
Select switch to change the bank. The alpha tag of the
current bank is displayed on the bottom line.
Any programmed system can be assigned to a
bank, and the system numbering can be different for
each bank. Only the systems in the currently selected
bank are selected or scanned, and at least one bank is
always programmed. Unique bank parameters include
the default emergency system/group (see Section
3.5.6) and Home system/group (see Section 3.5.9).
When a different bank is selected, the last
selected system in that bank is displayed, and the
displayed group is the last selected group of that
system. These are the only user selected functions that
are stored on a per bank basis.
3.5.3 CALL INDICATOR
With low tier models, the call indicator is the
yellow LED to the left of the channel display (see
Figure 3-1). With high tier models, it is “
C” in the
upper part of the display as shown in the following
illustration.
The purpose of this indication is to show that a
call was received while the user was away from the
vehicle. It is turned off by pressing any button or
turning transceiver power off and then on. If scanning
and the “last received” configuration is programmed
(see Section 3.7.4), the system and group of the last
call are displayed. Otherwise, the currently selected
system/group is displayed.
With LTR systems, each selectable and the two
fixed priority ID codes can be programmed to enable
the call indicator. With conventional systems, each
group can be programmed to enable it. The Call indi-
cator is activated if the transceiver unsquelches for 2
seconds or longer. Therefore, if Call Guard squelch is
programmed on a group, it must also be detected for
the call indication to appear (unless it is disabled by
the monitor mode).
