GENERAL OPERATION

Conventional Operation

This is a non-trunked operation mode which accesses independent radio channels (there is no automatic access to several channels as with trunked operation). Monitoring before transmitting may not occur auto- matically in this mode, so you may have to manually monitor the channel before transmitting to make sure that it is not being used by anyone else (see page 25). Selecting a conventional channel selects a transmit and receive frequency and other parameters such as Call Guard squelch coding.

SMARTNET/SmartZone Operation

This is a trunked operating mode that uses ID codes to select which mobiles are being called and which calls are received. Monitoring is performed automatically and special messages and tones indicate busy and out-of-range conditions. Enhanced features include roaming (Smart- Zone only), telephone, private, and emergency calls, Call Alert, and messaging. Operating features unique to SMARTNET/SmartZone chan- nels are described starting on page 34.

This radio supports only the SMARTNET II trunking protocol. It does not support the SMARTNET I (also referred to as Type I) protocol. When a SMARTNET or SmartZone channel is selected or the radio is powered up on one of those channels, it searches for a control channel and attempts to register on the radio system. Once a control channel is found, the alias (name) of the selected channel is displayed. If a control channel could not be found (because of an out of range condition or the system ID is not correct, for example), “NO SYS” is displayed and the radio continues to search for a control channel.

The control channel transmits and receives system information to and from all radios registered on the system. Therefore, once a control channel is found, it is continuously monitored for incoming call informa- tion and is used to make call requests. The radio automatically changes to a traffic channel to place and receive calls and then returns to the control channel when the call is complete.
