Removing Temperature Sensor
Note
Prior to removal make sure which of the two temperature sensors needs to be replaced.
1. Using a Torx screwdriver No. 20, remove the rear panel of the rack.
2. Unplug the connector of the temperature sensor concerned.

work on the transmitter rack. This will prevent injury due to electric shock and avoid dam-
age to the instruments.
