7. MAINTENANCE
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 grave-
ly impair safety.
7.1. CLEANING
Disconnect the unit 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.
7.2. REPLACING THE BATTERIES
If the batteries no longer take a charge, in other words, if they discharge too rapidly for you to be able to make recordings, they
must be replaced.
Withdraw the old batteries (see §1.4) and replace them with new ones.
Spent batteries must not be treated like ordinary household wastes. Take them to the appropriate collection point for recycling.
