Shock hazard. The GTR 8000 Base Radio contains dangerous voltages which can cause electrical
shock or damage to equipment. Set the power supply switches for the affected equipment to the
Off (0) position when servicing this component in the base radio.
Powering down the base radio causes any affiliated subscribers to relocate to another channel at the site or
another channel at an adjacent site. It is recommended to disable the base radio before powering down, so
that the system does not attribute the loss of a channel to a failure. You can disable a base radio using
Unified Event Manager or the Configuration/Service Software (CSS).
