seconds or not at all. When a priority system/group is sampled while listening to a message on some other system/
group, a series of “ticks” are heard. These ticks are brief interruptions of the audio signal that occur when sampling
takes place.
This feature is available only on conventional systems. In addition, sampling does not occur while listening to an
LTR or Multi-Net call or when transmitting any type of call. If the PRI option switch or Menu mode “PRIORITY”
parameter is available (see page 18), priority sampling can be turned on and off.
Receive-Only Groups
Conventional systems can be programmed so that transmitting is disabled (monitoring only is permitted). If the
PTT switch is pressed with one of these systems selected, the intercept tone sounds and “TX DISABLE” is displayed.
MENU MODE AND OPTION SWITCHES
Using Menu Mode
If the transceiver is equipped with a MENU option switch (see next section), the Menu mode can be selected to
select various transceiver functions. The functions selectable in the Menu mode are indicated by an “X” in “Menu”
column of the table on page 19.
NOTE: You probably will not be able to select all the functions in this table because some may be controlled by an
option switch or they may not apply so have been removed from the menu by system operator programming.
To change an operating parameter using the Menu mode, proceed as follows:
1. To select the Menu mode, press the MENU switch.
2. To select the desired parameter, turn the front panel Select switch until it is displayed.
3. If the parameter has only on/off choices, the current status is shown as “ON” or “OF” in the status display
(between the system and group numbers). To change the status, press the Select switch.
4. If the parameter has several choices, the current status is displayed by pressing the Select switch. Then to change
the status, rotate the switch.
5. The Menu mode is exited and the choices selected in the following ways:
• Pressing the MENU switch
• Automatically 2 seconds after changing a parameter or 10 seconds after no activity.
If a call is received or transmitted while in the menu mode, the Menu mode is exited and any changes are saved.
The parameters programmed in the Menu mode are described in the information which follows.
Option Switches
This transceiver can be equipped with up to six option switches as described on page 3. The function of each
switch is indicated by a label on the switch. The functions which can be controlled by these switches are indicated in the
table on page 19. A description of each of these functions follows.
