GTR 8000 Base Radio
Figure 9-17 External Dual Circulator/Isolator Tray (UHF)
These modules can be replaced individually, or if you order them together, you may receive the modules already
secured to a tray.
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 system.
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 that you disable the base radios before powering
down, so that the system does not attribute the loss of channel to a failure. You can disable a base radio
using Unified Event Manager or the Configuration/Service Software (CSS).
