Dynamic regrouping is de‐activated by either selecting another talk group/channel (if
possible), or by send a request to de‐activate dynamic regrouping. When deactivated, the
radio will return to the talk group that was active when the dynamic regroup request was
sent.
Dynamic regrouping is not preserved between power off‐on.
FAILSOFT OPERATION
If the radio is unable to access the trunking system, it can be programmed to enter failsoft
mode. In failsoft mode the radio switches to a programmed conventional P25 or analog
channel.
Failsoft mode is entered when either a trunking channel is selected and the radio fails to
register with the trunking controller, or the radio loses communications with the trunking
controller.
INSTALLATION
The CM1039 is supplied with a slim, slide‐on mounting cradle. The cradle can be screwed or
bolted in any convenient location in your vehicle (under or above the dash, on the centre
console, etc) using the mounting slots provided in the base. The CM1039 contains a built‐in
speaker and can be installed with the speaker facing upwards or downwards to ensure the
receiver audio is projected clearly. Alternatively, the CM1039 can be fitted with an
extension speaker if required. When installing the radio, avoid mounting it close to heaters
or air conditioners. Screw the mounting cradle to a firm surface. Slide the CM1039 into the
cradle from the front until it clicks into place. Finally, plug the power and antenna leads to
the sockets provided on the rear of the radio.
