If an LTR system is selected, the Free System Ringback feature is automatically selected when the PTT switch is
released. This feature signals you when the system is no longer busy (see page 16 for more information).
Out-of-Range - If an out-of-range condition exists, it is indicated by an intercept tone and “OUT-OF-RNG” in the
display. If an LTR system is selected and the System Search feature is available (see page 16), it may be selected to
automatically search for a free system.
If a Multi-Net system is selected and the Auto-Registration feature is available (see page 14), it automatically
changes sites when an out-of-range condition occurs. If these features are not available, drive the vehicle closer to the
radio system or away from shielding structures and try the call again.
4. Dial the number using the keypad on the microphone. If the transmitter keys automatically when a number is
dialed, the PTT switch does not need to be pressed while dialing.
5. When you finish dialing the number, release the PTT switch if it was pressed.
With LTR calls, ringing of the other party is then heard. With Multi-Net calls, a short tone sounds to indicate that
the number was accepted by the system. Then, if it is a telephone call, ringing of the other party occurs (or a busy tone is
heard if the line is busy). If it is a special call, a second short tone sounds to indicate that speaking should begin. No
ringing of the other party occurs.
6. The PTT switch must be pressed to talk and released to listen. You cannot talk and listen at the same time because
no messages are received while the PTT switch is pressed.
7. When the conversation is finished, terminate the call by pressing the # key. Place the microphone back on-hook.
Receiving a Telephone or Special Call
1. Turn power on and set the volume level if required.
2. Select the system/group programmed for these calls or enable system scanning by pressing the SCAN switch (if
available).
3. When a ringing tone is heard, answer the call in the normal manner (press the PTT switch to talk and release it
to listen).
4. When the conversation is finished, terminate the call by pressing the # key. Three beeps indicate that it has been
terminated. Place the microphone back on-hook.
Calling a Mobile From a Landside Telephone
Mobiles can also be called from a landside telephone. With some radio systems, a mobile may have a unique tele-
phone number so that it can be dialed directly. With others, the number of the radio system is dialed. Then when the
system answers, a beep sounds and the number specifying the mobile being called is dialed. This number is supplied to
you by your system operator, and it must be dialed using a tone-type telephone. Depending on the type of call being
made, a ringing tone then sounds or another beep sounds which indicates that speaking can begin.
