Motorola XPR 4380 Manuale Utente

If your radio receives a scrambled call that is of a different 
Privacy Key, OR a different Key Value and Key ID, you will 
either hear a garbled transmission (Basic Privacy) or nothing at 
all (Enhanced Privacy).

The LED lights up solid green while the radio is transmitting and 
blinks green rapidly when the radio is receiving an ongoing 
privacy-enabled transmission.

NOTE: Some radio models may not offer this Privacy feature. 

Check with your dealer or system administrator for 
more information.

Procedure:
Press the programmed Privacy button to toggle privacy on or 
off.

This feature allows your radio to extend communication beyond 
the reach of a single site, by connecting to different available 
sites via an Internet Protocol (IP) network.

NOTE: This feature is not applicable in Capacity Plus.

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.
