Radio Function
D1 Multiple
certified
standard
protocols for
users to
choose from.
1. Protocol provided by Analog system
a. CTCSS / CDCSS
b. 2 Tones
c. MDC 1200
d. Uni DVOA
2. Protocol provided by Digital System
a. DMR
b. P25(C)
3. Protocol provided by Trunking system
a. P25(T)
D2 Analog and
digital signal
mixed
1. Automatically distinguish the coming
signal mode (analog or digital) and
protocol, then automatically turn on
the corresponding module of demod-
ulation and decoding.
2. Automatically use the same signal
mode and protocol as the coming
message once the radio is in "Hang
times".
3. Users can achieve this function without
switching the channels.
