Part No. 001-5300-007CD-NR
3.10 HOME ZONE/CHANNEL SELECT
If the HOME zone option switch is programmed,
pressing it selects the preprogrammed home zone and
channel. This provides a quick way of returning to a
frequently used zone and channel. The transceiver is
also programmed so that either the home or last
selected zone/channel is automatically selected when
power is turned on.
3.11 POWER OUTPUT SELECT
Each conventional channel and SMARTNET/
SmartZone and P25 Trunked system can be
programmed for High, Low, or Switchable transmit
power. If Switchable power is programmed on the
channel, the
Tx PWR option switch can then be used
to select high or low transmitter power. All models
support switchable power.
Pressing the
TX PWR switch toggles the power
setting. The new level is flashed in the display when
this switch is pressed as “HI POWER” or “LOW
POWER”. If selectable power is not permitted on the
current channel, the fixed power level is flashed as
“FIXED HIGH” or “FIXED LOW” and no power
change occurs. The selected power level for a channel
is permanent until it is manually changed again.
3.12 ALERT TONE SELECT
The various alert tones that sound are described
in Section 6.1 on page 35. These tones can be enabled
and disabled if the
TONE option switch is
programmed. To turn all tones off, press this switch
and “TONE OFF” is displayed. Then to turn all tones
on again, press it and “TONE ON” is displayed. If this
switch is not programmed, tones are fixed in the on or
off condition by programming.
3.13 POWER TURN-OFF DELAY
The transceiver can be installed so that the
vehicle ignition switch as well as the front panel
power switch of the transceiver control power. This is
done by connecting the accessory cable ignition switch
input to the vehicle ignition switch. Refer to the Instal-
lation section of the 5300 Service Manual for more
information. A power-off delay of up to 254 minutes
or forever can then be programmed.
Both the ignition switch and the power switch
must then be on for transceiver power to turn on. The
delay can be overridden at any time by turning power
off using the front panel power switch or turning the
ignition switch back on.
This turn-off delay can allow calls to be received
or the horn alert to be active for a time after the igni-
tion switch is turned off. At the same time, advantages
of ignition switch control are utilized such as
preventing the battery discharge that may occur if the
transceiver is left on for an extended period (see
Section 6.5).
3.14 HORN ALERT
The horn alert feature sounds an external alert
such as the vehicle horn when certain calls are
received. It is available if a Horn option switch is
programmed and the proper connection has been made
to the external alert. The horn alert output is pin 4 of
the accessory cable, and an external driver circuit of
some type is usually required. Refer to the Installation
section of the 5300 Service Manual for more informa-
tion on how to install this feature.
Additional information on the horn alert feature
follows:
• It activates when receiving any Unit call in the
conventional mode and any Private/Unit and Call
Alert (paging) call in the SMARTNET/SmartZone
and P25 Trunked modes. It does not sound when
receiving standard Group or Telephone calls, and is
not programmable on a per call basis.
• It must be manually enabled and disabled by the
Horn option switch. It is not controlled by the
vehicle ignition switch. When it is enabled, “HORN
ON” is briefly displayed, and when it is disabled,
“HORN OFF” is briefly displayed. It defaults to the
off mode whenever power is turned on.
• If a power turn-off delay is programmed as just
described, it is functional during that delay.
• When activated, it can be programmed to sound for
three 1-second beeps or continuously for 2-90
seconds. It then turns off until another call is
received.
