4.1 OPTION SWITCHES

NOTE: For descriptions of the functions controlled by
these switches, refer to the section of this manual
referenced in the last column of Table 4-1.
The six option switches on the front panel (one is
located to the left of the display) can be programmed
by the PCConfigure programmer to control a different
set of functions for each of the three operating modes.
Therefore, up to 18 different functions can be
controlled by these switches (six each for conven-
tional, SMARTNET/SmartZone, and P25 Trunking).
The available functions in each mode and the section
in which each is described are shown in Table 4-1.

4.2 TIME-OUT TIMER

The time-out timer disables the transmitter if it is
keyed for longer than the programmed time. It can be
programmed on each channel for times of 15 seconds
to 3 minutes, 45 seconds or it can be disabled.
If the transmitter is keyed continuously for longer
than the programmed time, the transmitter is disabled,
a continuous tone sounds, and "TX TIMEOUT" is
displayed. Five seconds before time-out occurs, a
warning beep sounds to indicate that time-out is
approaching. The timer and tone are reset by releasing
the PTT switch.
A different time can be programmed for each
system, and the timer can be enabled or disabled on
each conventional channel. With conventional chan-
nels, a penalty time can also be programmed that
prevents further transmissions for a certain time after
the transmitter is disabled (see Section 5.6).
One use of this feature is to prevent a channel
from being kept busy for an extended period by an
accidentally keyed transmitter. It can also prevent
possible transmitter damage caused by transmitting for
an excessively long period.

4.3 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. Pressing and

or later.
holding this switch until a tone sounds makes the
currently selected zone the new Home zone. The radio
is also programmed so that either the home or last
selected zone/channel is automatically selected when
power is turned on (see Section 3.1).

4.4 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 or system, 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 or system, the fixed power level is
flashed and no power change occurs. The selected
power level is permanent until it is manually changed
again.The power levels are set at the factory or when
the radio is tuned using the PCTune™ software. The
factory default low power setting is one-half the high
power setting.

4.5 ALERT TONE SELECT

The various alert tones that sound are described
in Section 7.1 on page 51. 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. Alert tones are totally
disabled when the Surveillance mode is programmed
(see Section 4.9).
The Alert Tone volume* can be adjusted relative
to the volume control setting. This is done by
programming and also by the user if the TN VOL
option switch is programmed. Relative levels of –170
to +170 can be set with "0" the default setting. A
minus value decreases the tone volume and a plus
value increases it. The user adjusted level permanently
overrides the programmed level if applicable.
