2.4 DISPLAY

Figure 2-4 Graphical Display
The front panel display is shown above. Icons are
typically shown in the upper part of the display and
text messages in the lower part. The icons are as
follows:
- When the scan or the scan list edit mode is
enabled, indicates that the displayed channel is in the
scan list and scanned (see Section 4.8).
- When the scan or the scan list edit mode is
enabled, indicates that the displayed channel is a
priority channel. If dual priority is used,
that it is a second priority channel.
- Low battery indication (see Section 3.4).
- Voice encryption is enabled or an encrypted
call is being received. This indication flashes when an
encrypted call is received on a digital channel (see
Section 10.2.7).
- Priority or radio wide scanning is enabled (see
Section 4.8).
- In the surveillance mode only, indicates that
the transmitter is keyed (see Section 4.7). This icon is
displayed in place of the preceding scan mode icon
when applicable. They do not conflict because the
scan icon is not displayed in the transmit mode.
- Repeater talk-around is enabled (see
Section 5.8).
- The Monitor mode is enabled by the Monitor
option switch or menu parameter (see Section 5.3).
The radio can also be programmed so this icon is
displayed when the Normal mode is selected by the
Normal/Selective function (see Section 5.5.2).*

enabled which allows the user to edit radio parameters.
- An interconnect (telephone) call is in progress
(see Section 6.6).
