switches. The F1 switch is Back/Clear, and the F2
switch is Menu Select/Enter. If the menu mode is
disabled, these switches can be programmed for other
functions.
Only the enabled menu items which apply to the
selected channel type are displayed. For example, if a
conventional channel is selected, only the enabled
functions for conventional channels are displayed.
When in the menu mode, messages continue to be
received on the selected channel. However, the display
does not indicate who is calling. Pressing the PTT
switch exits the menu mode and keys the transmitter.
The menu mode operates as follows:
1. To select the menu mode, press the F2 key. Up to
three menu parameters are then displayed as shown
in the preceding photo.
2. To scroll up or down through the menu parameter
list, press the Up/Down switch. The selected
parameter is indicated by a dark bar.
3. To display the available modes for a highlighted
parameter, press the F2 switch. The currently
selected mode is indicated by an asterisk.
4. Press the Up/Down switch to highlight the desired
mode. Then press the F2 key to select that mode.
5. To step back to the previous level or exit the menu
mode, press the F1 (Clear) key.
4.3 TIME-OUT TIMER
The time-out timer disables the transmitter if it is
keyed continuously for longer than the programmed
time. It can be programmed for 15 seconds to 3
minutes, 45 seconds or it can be disabled.
If the transmitter is keyed for longer than the
programmed time, the transmitter is disabled, a contin-
uous 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 may also be programmed that
prevents 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.
4.4 HOME ZONE/CHANNEL SELECT
If the Home Zone option switch or menu param-
eter is programmed, it selects the preprogrammed
home zone. The selected channel is displayed if the
channel switch is enabled, and the preprogrammed
home channel is selected if it is disabled. The trans-
ceiver is also programmed so that either the home or
last selected zone is selected when power is turned on.
Refer to Section 3.3 for more information.
4.5 POWER OUTPUT SELECT
Each conventional channel and SMARTNET/
SmartZone and P25 Trunked system can be
programmed for high, low, or switchable power. If the
High/Low Power option switch or menu parameter is
programmed and selectable power is programmed on
the current channel or system, high and low trans-
mitter power can be selected. All models support high
and low power.
The new level is flashed in the display as either
“HI POWER” or “LOW POWER”. If selectable
power is not permitted on the current channel,
“FIXED LOW” or “FIXED HIGH” is flashed and no
change occurs. The selected power level for a channel
is permanent until it is manually changed again. The
low power mode may be automatically selected during
a low battery condition (see Section 3.4).
4.6 ALERT TONE SELECT
The various alert tones that sound are described
in Section 7.1. These tones can be turned on and off if
the Alert Tone option switch or Tones menu parameter
is programmed. When all tones are off, “TONE OFF”
is momentarily displayed, and when all tones are on,
“TONE ON” is momentarily displayed. If this switch
or menu parameter is not programmed, tones are fixed
* This feature requires 51xx operating (Flash) software
1.9.0 or later and PCConfigure 1.20 or later.
