output cable
f, and move both cables to one side. Unplug both ends

clamp through 90° to clear the module.
5. Slide the reciter out of the subrack, taking care not to damage any of
the cables.
Refitting 1. Slide the replacement reciter into the subrack and secure it with the
retaining clamp. Ensure that you set its hex switch
i to the same
number as the original reciter.
2. Reconnect all the front and rear panel cables previously disconnected.
Ensure the front panel cables are retained by the cable retaining clips

Important Do not force the system control bus behind the reciter
handle as this may damage the ribbon cable.
Note If you need to remove any front panel cables, simply pull the front
of the cable retaining clip down and then slide it out from the sub-
rack until it reaches the end of its travel.
