SMARTNET/SMARTZONE FEATURES

2.To reset all talk and announcement groups to normal so that only the designated regrouping channel is on the dynamic group, manually select the designated regrouping channel if you know it. If this channel is not selected or there is no designated regrouping channel, all trans- missions occur on the dynamically assigned group regardless of which channel is selected, and the regrouping tone sounds each time the PTT switch is pressed.

3.When regrouping is canceled by the dispatcher, transceiver operation returns to normal.

SmartZone Features

Introduction

As described on page 23, the SmartZone® mode provides wide area coverage by allowing roaming between SMARTNET and conventional sites. SmartZone operation is the same as SMARTNET with the following additional features:

Determining Current Site and Searching For New Site

To determine the current radio site, momentarily press the Site Search option switch (if programmed). If currently registered on a site, “SITE x” is displayed, where “x” is the site number. If the site is locked (see following), “LOCK x” is displayed instead. The display then indi- cates the RSSI (Receive Signal Strength Indicator) value of the current site as “RSSI x”. If the Site Search switch is not pressed again, this mode is exited and the normal channel display returns.

To search for a new site, repeatedly press the Site Search option switch while “SITE x”, “LOCK x”, or “RSSI x” is displayed. Each time it is pressed, information for the next site is displayed. To select the displayed site, simply do not press the switch again and that site is selected when the normal channel display returns. If site lock is on (see next section) the radio will be locked on this site when this function is exited.
