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
the EK 2020 D flashes red).
