Notes:

•Charging a completely discharged rechargeable battery of the HDE 2020 D takes approx. 2½ hours at room temperature.

•Charging a completely discharged rechargeable battery of the EK 2020 D takes approx. 5 hours at room temperature.

•However, 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 charg- ing process will be interrupted until the tem-

perature is again within the permissible range (the LED of the HDE 2020 D or the LED of the EK 2020 D flashes red).
