Product Description
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 other radios.
Indivadual call
It supports point to point communications,only you and the other can talk with each othe,protecting the privacy.
Group call
A certain members can be set as a group to communicate together,which greatly improve the efficiency of the communications among the group.
