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

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

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
