An empty battery is fully charged after 

about 2 hours. Charging is only possible 

within a temperature range of +5 °C to 

+40 °C (+41°F to +104°F). If the tempera-

ture rises/falls 5°C above/below this, i.e 

drops to 32°F or rises to 113°F, the charge 

symbol flashes a warning. The mains volt-

age specified on the power supply unit 

must not be exceeded (Operating time,
