Danger
Electric shock
Parts carrying dangerous voltages that may cause injury may be exposed if
the AC adapter / charger unit is damaged.
⇒
Do not use an AC adapter / charger unit that has been damaged.
Caution
Destruction
The wrong AC line voltage, condensation, excessively high or low
temperatures and poor ventilation can lead to destruction of the
AC adapter / charger unit.
⇒
Before connecting up the AC adapter / charger unit make sure that
the operating voltage of the AC adapter / charger unit is the same as the
AC line voltage.
⇒
Do not use the AC adapter / charger unit if condensation has formed on
it. If condensation is unavoidable, e.g. because the instrument has been
moved from a cold to a warm room, wait until the unit has dried off before
connecting it up.
⇒
Only use the AC adapter / charger unit indoors and at temperatures
b5 °C and +45 °C.
