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.
