Time query
The current device time can be queried by calling the following IDs/callsigns:
DMR, NXDN® and P25: ID 9995. Both private and group calls are
interpreted.
D-STAR®: call is sent to .......T (7 spaces and an T, replace dots with
spaces), or DTMF codes CD is entered.
C4FM: Special command/cross mode private call DTMF code (by default it's
*) is entered followed by DTMF codes CD.
The current time will be announced by voice. The DMR/NXDN®/P25 time query
ID can be changed on the Settings page, Voice announcements section.
D-STAR® unlink command
The openSPOT4 is designed to be always connected, however, the unlink (U)
command is supported and activates the Null connector (which - as its name
says - does not connect anywhere).
You can unlink if a call is sent to .......U (7 spaces and a U, replace dots with
spaces), or DTMF code # is entered.
