Digital and analog 2 working modes

TD500 can meet different communications needs,as it supports digital and analog 2working

modes.

Dual slots

TDMA dual slots can greatly increase the communication capacity.

Voice encryption

Encryption key can be set via software,which can srambling and descrambling the voice call in

encryptioned

channels.Usaully one radio can only have one encryption key.

Digital signaling

TD500 can support varieties of calls,it supports indivadual group and all call; it also can kill and

revice

Indivadual call

It supports point to point communications,only you and the other can talk with each

othe,protecting the

Group call

A certain members can be set as a group to communicate together,which greatly improve the

efficiency of the

All call

One radio can talk with all the radios that on the same channel,no matter which group the radio

is ,this is

very useful for dispatching.
