CONVENTIONAL FEATURES

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

channels are described starting on page 32.

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.
