2.3.6 LOW BATTERY INDICATION
When the battery voltage falls below a preset
level, the
icon appears in the display. This
icon stays on until power is turned off. In addition, the
following low battery indications may be programmed
to occur:
•
The amber BATT indicator on the top panel lights.
•
A beep sounds once per minute in the standby mode.
•
A beep sounds each time the PTT switch is pressed.
The battery should be recharged as soon as prac-
tical after a low battery indication appears. Refer to
Section 5 for more battery information. There is also a
battery saver function that can be enabled by program-
ming. This function uses the RSSI level to determine
when the site is very near and then automatically
switches to the low transmit power output level.
2.3.7 CHANNEL AND ZONE SELECTION
Channel Select
To change the current channel, rotate the 16-posi-
tion channel selector knob on the top panel to the
desired position. With SMARTNET/SmartZone chan-
nels, the channel is always indicated by alias (name).
With conventional channels, the channel number or
frequency may also be displayed (see Section 2.4.2).
Zone Select
A zone is a group of up to any 16 conventional
and SMARTNET/SmartZone channels defined by
programming (see Section 1.2.4). Up to 16 zones can
be programmed for a total of 16 x 16 or 256 channels.
One use of zones may be to select groups of channels
programmed for operation in different geographical
areas or radio systems. Zones are selected as follows:
1. Press the Zone option switch and the alias (name) of
the current zone is flashed in the display.
2. Use the number keys to enter the desired zone
number or scroll through the available zones using
the
and
keys.
3. Once the desired zone is displayed, press the ENT
key or wait 4 seconds.
2.3.8 HOME ZONE
The radio can be programmed with a home zone.
Then when power is turned on, the radio can be
programmed so that either the home or last selected
zone is automatically selected.
If the Home Zone option switch is programmed,
it can be used to quickly select or change the home
zone. To select the home zone, momentarily press this
switch. Then to change the home zone to the currently
selected zone, press and hold this switch until a tone
sounds (approximately 1 second).
2.3.9 TIME-OUT TIMER
The time-out timer disables the transmitter if it is
keyed for longer than the programmed time. On each
