CTCSS/DCS Decode
When the transceiver edit this function ,it only can hear the orther party calling when receive the matching CTCSS/DCS signal.
Other transceiver includes the same CTCSS/DCS signaling seting and no signialing seting also can hear your calling.
Wide/Narrow Band Setup
According to the basis of national conditions ,users can set channel spacing as 25K (wide band), 20K ( middle band) or12.5K
(narrow band) to communicate on the transceiver by programming software.
This transceiver can realize 25K (wide band), 20K (medium band) or 12.5K (narrow band) as communication way.
optional Signaling
Users can enable or disable the Optional Signaling in every channel by programming software. This Signaling function is similar
to CTCSS/DCS which embodies functions as Selective Call, Group Call, All Call, PTT ID, and Remotely stun and Waken.
PTT ID: If current channel is edited with PTT ID, the transceiver will send transmitting ID when pressing or releasing PTT

key.
You can set group call wildcard for each group by programming software . (DTMF character A. B.C.D.*** or “#”). The caller can

call different groups by sending different group call codes. When the receiving party receives a valid ID code, one or all of the
characters would be replaced by wildcard characters and the receiving part can realize all call, group call or selective call. It
is much easy and flexible to realize all call, group call and etc by using group call code.
For example:Group code :"C"
