2.4 General Services
2.4.1 Supplementary Service
Hytera DMR has the same supplementary service feature mechanism with Motorola.
Hence, these two brands of radios can communicate with each other.
Hytera DMR radios have five supplementary services as follows:
Radio Check
Remote Monitor
Alert Call
Radio Disable
Revive
You can initiate any of these services via the radio menu or using the shortcut key
assigned with One Touch Call feature. Meanwhile, the target radio must have the
Decode feature to decode the command accordingly, otherwise, it will not be able to
respond to the received command.
Radio Check
This feature is mainly used to check whether the target radio is in use in the system
without disturbing it. When a Radio Check command is received, the target radio will
give no visible or tone indication but will send back a confirmation message to the
initiating radio automatically. This command is mainly used to see if the target radio
is available. After the radio replies the confirmation message, the initiating radio can
call the target radio or go on controlling it through other commands such as Remote
Monitor, Radio Disable, etc.
To use the Radio Check feature, the Encode and Decode feature must be enabled
for the initiating radio and the target radio respectively via the CPS.
Remote Monitor
With this feature, you can activate the microphone of the target radio remotely, so
that the microphone will transmit the background voice to the initiating radio secretly.
In this way, the initiating radio can monitor the target radio’s communications. You
can set the time for remote monitor via the CPS.
The Remote Monitor feature is used to check the status of a radio which is already
turned on but has no response. Such problem occurs in the following factors:
