displays telephone numbers in the phone mode and
various error and status messages.
Status Display -
These two characters indicate the
following status information:
- Rotating clock-like symbols in both positions
indicate that system scanning is occurring. This is
also indicated during programming.
- This symbol in the left position indicates that
the displayed system is in the scan list. Likewise,
this symbol in the right position indicates that the
displayed group is in the scan list.
- This symbol in the right position indicates that
group scanning is occurring.
P1/P2 -
When a conventional system is selected,
“P1” indicates that a call is being received on a
priority 1 group, and “P2” indicates that a call is
being received on a priority 2 group. Refer to
Section 3.5.17 for more information.
ON/OF -
When the menu mode is selected by the
MENU switch, “ON” indicates that the displayed
parameter is active, and “OF” indicates that it is
inactive.
- Indicates that the function controlled by the
option switch above it is active. For example, this
symbol below the Scan switch indicates that the

require this indicator.
- Indicates that the displayed system/group is
programmed for telephone or special calls.
- Indicates that encryption is enabled.
MON -

enabled by taking the microphone off-hook or pressing
the MON switch (conventional systems only). The
monitor mode disables Call Guard squelch and scan-
ning so that all messages are heard on the channel.
BUSY -
Indicates when the selected system/group is
busy (conventional systems only). If this indication
appears but no message is heard and Call Guard
squelch is programmed, a call for someone else was
probably detected.

user was away from the vehicle. It is turned off by
pressing the Select switch, an option switch, or the
