Except for the batteries, the instrument contains no parts that can be
replaced by personnel who have not been specially trained and accredited.
Any unauthorized repair or replacement of a part by an "equivalent" may
gravely impair safety.
4.1. CLEANING
The device must be kept perfectly clean.
Disconnect the instrument completely.
Use a soft cloth, dampened with soapy water. Rinse with a damp cloth and dry
rapidly with a dry cloth or forced air. Do not use alcohol, solvents, or hydrocarbons.
4.2. REPLACEMENT OF BATTERIES
Any handling of the battery compartment cover must take place on a clean device
and in a clean environment.
If, during the self-test, only half of the indicators light, you must replace the batteries.
„ Disconnect anything connected to the device.
„ Using a screwdriver, unscrew the two captive screws of the battery compartment
cover located on the back of the device.

correctly closed.

Spent batteries must not be treated as ordinary household waste. Take
them to the appropriate recycling collection point.
