Care, maintenance, ambient conditions
Care
Use a soft, clean cloth for cleaning the unit. Do not use any solvents.
Maintenance
A lithium-ion battery has only a limited service life. When the operating
time of a unit with a fully charged battery has become clearly shorter, the
battery must be replaced.
There are no user-serviceable parts inside the handset, the charging
station and the plug-in power supply unit.
Opening these units and any interventions into the units are allowed only
to authorised service personnel.
Ambient conditions
Your handset is equipped with a sturdy housing, is shockproof and water-
protected.
Nevertheless, protect your unit against wetness, strong heat (e.g. solar
radiation behind glass) and dirt.
