Using the Signaling
Color Code is the signaling to be used for facilitating communication within a group if the same channel is shared by several
groups.
Sharing the Same Channel (Frequency) by Several Groups (Color Code)
Color Code is a digital signaling type having the same function as analog QT tone or DQT code. This signaling is used when
the transceiver transmits or receives on a digital channel.
The transceiver mutes calls from a zone having a restricted Color Code if a Color Code is configured for each channel.
Therefore, a user can communicate in a group without listening to conversations from other groups.
The
transceiver can distinguish the signaling even if the transceiver receives any signaling during a call since this signaling
type has a continuous waveform.
The following is transmission and reception behavior of a Color Code:

Description
Reception
If the transceiver receives a signal and the received Color Code matches the Color Code
preconfigured for the transceiver, the transceiver unmutes the speaker and emits the received
audio from the speaker.
Transmission
The transceiver sends the preconfigured Color Code while transmitting. Pressing the PTT
switch
causes the transceiver to send the Color Code.
Note
The transceiver transmits with the signaling of the received signal regardless of the configuration in Transmit Mode if
within
the amount of time configured in Signaling Reset Timer after the transceiver receives a signal on a channel with
“Mixed” configured in Channel Type.
