Motorola SL4010 用户手册

This feature allows your radio to extend communication beyond 
the reach of a single repeater site by operating on multiple 
repeater sites connected together via an Internet Protocol (IP) 
network.

When the radio moves out of range from one site and into the 
range of another, it connects to the new site's base station to 
send or receive calls/data transmissions. Depending on your 
settings, this is done automatically or manually.

If the radio is set to do this automatically, it scans through all 
available sites when the signal from the current site is weak or 
when the radio is unable to detect any signal from the current 
site. It then locks on to the base station with the strongest 
Received Signal Strength Indicator (RSSI) value.

In a manual site search, the radio searches for the next site in 
the roam list that is currently in range (but which may not have 
the strongest signal) and locks on to it.

NOTE: Each channel can only have either Scan or Roam 

enabled, not both at the same time.

Channels with this feature enabled can be added to a particular 
roam list. The radio searches the channel(s) in the Members list 
during the automatic roam operation to locate the best site.

A Members list supports a maximum of 16 channels (including 
the Selected Channel).

NOTE: You cannot manually add or delete an entry to the 

Members list. Check with your dealer or system 
administrator for more information.

When the radio is actively searching for a new site:

Procedure: 
Press the programmed Site Lock On/Off button.
