Motorola ic502 用户手册

Direct Talk allows for two-way radio communication
“off the network” between two or more phones equipped 
with this capability. This feature is very useful in areas 
without network coverage. 

You can make –

䢇

Code calls – two-way radio calls conducted off the network 
and using open channels and codes. In these calls, anyone 
using your same channel and code can hear your 
conversation.

䢇

Private calls – two-way radio calls conducted off the 
network and using the wireless phone numbers of the 
participants. In these calls, others using the same channel 
cannot listen in.

When using Direct Talk mode, the two phones should be a 
minimum of six feet apart to maximize performance and 
improve transmission range. You can only make Direct Talk 
calls to users located within your range. This varies according 
to terrain, man-made structures, and atmospheric conditions.

The following features are not available while in Direct Talk 
mode:
