Using the charger

̈ 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.

channel. The channel copy function allows you to copy the current channel
