Notes:

yCharging a completely discharged rechargeable battery takes approx. 2½ hours at room temperature.

yHowever, the charging process may take longer if:

the rechargeable battery is deep discharged and first has to be reconditioned by a deep discharge recovery charge,

the temperature of the built-in rechargeable battery is over 40°C or below 3°C, since, in order to protect the rechargeable battery, the charging process will be interrupted until the temperature is again within the admissible

range (the LED flashes red).

yAn additional temperature protection prevents overheating inside the charging case. If the temperature inside the charging case exceeds safety limits, the charging process will be interrupted and will only be restarted when the charging case has cooled down.

yWhen not using the receivers for extended periods of time, charge them about every six months in order to prevent deep discharge damage to the rechargeable batteries.
