Working Advice
Temperature Monitoring for Battery Operation
When the radio charger is operated only via bat-
tery (no mains supply), the battery temperature
is monitored.
– When the battery temperature is below
–10 °C or above 50 °C, the temperature
warning k flashes on the display.
– When the battery temperature is above
70 °C, the radio charger automatically
switches off to protect the battery. When the
battery has cooled down, the radio charger
can be put into operation again.
Recommendations for Optimal Handling of the
Battery
Protect the battery against moisture and water.
Store the battery only within a temperature
range between 0 °C and 45 °C. As an example,
do not leave the battery in the car in summer.
A battery that is new or has not been used for a
longer period does not develop its full capacity
until after approx. 5 charging/discharging cycles.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.
