The transmitter rack contains two fans as standard; one of these can be reached only from
the front and the other only from the back. However the removal sequence is the same in
both cases.

1. Using a Torx screwdriver No. 20, remove the front panel of the power distribution to re-

place the front fan, or the rear panel of the transmitter to replace the rear fan.

2. Switch off automatic line fuse 

 (rear fan) or 

 (front fan).

3. Undo the four screws on the fan housing and remove the cover.

Always make sure that the power supply is disconnected before commencing any service 
work on the transmitter rack. This will prevent injury due to electric shock and avoid dam-
age to the instruments.
