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.
5.1. 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.
5.2. REPLACEMENT OF BATTERIES
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.
Withdraw the spent batteries and replace them with two new
batteries (AAA or LR3 1.5V alkaline batteries).
Close the battery compartment cover and make sure that it
is completely and correctly closed.
Screw the two screws back in.
Spent batteries must not be treated as ordinary
household waste. Take them to the appropriate
recycling collection point.
