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 Mul

SYSTEM SCAN Introduction The system scan feature monitors the programmed systems of the current bank. When a message is detected that the transceiver is programmed to receive, scanning stops and the message is received. Shortly after the message is complete, scanning resumes. System scanning is turned on and off by the SCAN option switch (see page 3). When system scanning is enabled, a triangle ( ∆ ) is indicated in the display below the switch. The microphone must also be on-hook for scannin

The transceiver can be programmed to either save or not save changes to the scan list when power is turned off. This programming is done by your system operator or by the Menu mode SCAN SAVE parameter if it is selectable (see page 18). If “ON” is selected, the changes are saved and the list is the same when power is turned back on. If “OF” is selected, they are not saved and the scan list reverts to the status that existed when “ON” was last selected. Transmitting In The Scan Mode When the tr

Group Scan The Group Scan feature can be programmed on each system by your system operator. Group scanning occurs whenever a system programmed for group scan is selected or scanned with the microphone on-hook (there is no switch for selecting this feature). Group scanning is indicated when all segments of the status display next to the group number are on. However, there is no group scan indicator when system scanning is occurring because rotating symbols appear in both locations of the stat

Conventional Operation With conventional operation, selecting a system actually selects a specific radio channel. Then selecting a group (if available) selects the mobile or group of mobiles being called or from which calls are received on that channel. There are no tones or display messages to indicate busy or out-of-range conditions. Therefore, a busy channel must be detected as described in the next section, and an out-of-range condition may exist if you are unable to get a response from

Proceed (Clear-To-Talk) Tone This is a short tone that sounds when the PTT switch is pressed, and it indicates that the radio system has been successfully accessed and speaking can begin. It is standard on LTR and Multi-Net systems and programmable by your system operator on conventional systems. This and other tones can also be disabled by system operator programming or by the Menu mode “RADIO SNDS” parameter if it is selectable (see page 48). With all types of calls on LTR and Multi-Net sy

If the system is busy, the busy tone sounds and the queue mode is entered automatically when the PTT switch is released. The busy tone then stops sounding and “IN QUEUE” is displayed. When the system becomes available, either a dial tone or beep sounds. The dial tone sounds if it is a telephone call, and a beep sounds if it is some other type of call. The call can then be placed in the normal manner. If no call is placed soon after this tone sounds, the queue mode is automatically exited and

When a call on a priority ID is received, the ID codes of the selectable groups are checked to see if any are the same. If one is the same, the transceiver switches to that group. If none are the same, the group number does not change and “PRIORITY 1" (or 2) is displayed. When a call on a block ID is received, “BLOCK CALL” is displayed and the group number does not change.

LTR MODE FEATURES Free System Ringback If a busy condition exists when making an LTR telephone call, the Free System Ringback feature automatically signals when the system is available. It operates as follows: When the PTT switch is released, the busy tone stops sounding and “RING BACK” is indicated in the display. Then when the system becomes available, a dial tone is heard and the number can be dialed. If dialing is not started within a few seconds, normal operation resumes. This feature is

Call Guard Squelch Control The Call Guard Squelch feature eliminates distracting messages intended for others on conventional systems. This is done by using a subaudible tone or digital code to control the transceiver squelch. This tone or code is unique to a mobile or group of mobiles on that system. The transceiver does not unsquelch unless the correct tone or code is detected. LTR and Multi-Net systems utilize ID codes to perform a similar function. Other types of tone decoders may also b

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 (se
