WARNING: Disconnect the instrument from any source of electricity.
• Use a soft cloth lightly dampened with soapy water. Rinse with a damp
cloth and then dry with a dry cloth.
• Do not get water inside the case. This may lead to electrical shock or
damage to the instrument.
• Do not use alcohol, solvents or hydrocarbons.

If the instrument is not used for an extended time period (longer than two months),
it is recommended that a complete charge and discharge of the battery is per-
