̈
Place the receiver into any charging compartment. The LED
¹
on the
receiver indicates the charge status.
Charging a completely discharged rechargeable battery takes approx.
3.5 hours at room temperature. However, the charging process may take
longer if:
• the rechargeable battery is deep discharged and first has to be recondi-
tioned by a deep discharge recovery charge,
• the temperature of the built-in rechargeable battery is below 3°C or
over 40°C, since, in order to protect the rechargeable battery, the
charging process will be interrupted until the temperature is again
within the permissible range and the LED
¹
lights up,
• the additional temperature protection of the charger interrupts the
charging process until the charger has cooled down.
