7.1.5.1 Removing the URC-200 Transceiver and UIB-100 Interface Box:
The following steps outline the procedure for removing the URC-200 Transceiver and
UIB-100 Interface Box from the Rack Mount System. It is necessary to remove the
interface box with the transceiver, because they cannot be detached while installed. If the
following steps cannot be performed due to space restrictions, it may be necessary to first
uninstall the tray from the 19” rack.
1. Ensure the power amplifier and transceiver are turned off, and that the power
supply is disconnected from the AC power source.
2. Disconnect the following cables from the transceiver and interface box:
• Cable assembly from the power supply to the interface box
• DC power cable from the interface box to the power amplifier
• RF cable from the transceiver to the power amplifier
• Remote connector from the transceiver to the power amplifier (only
applicable if Remote mode was being used on power amplifier)
• Audio cable / remote control connector on front panel of transceiver, if
present
3. Loosen the screws on the two front transceiver mounting clips.
4. Slide the transceiver and interface box out from under the mounting bracket, and
