Recommendations on how to save energy:
• Do not charge a battery when the ambient room temperature is above +40°C or below +5°C (above 104°F
or below 41°F). Charging below +5°C will harm the battery and shorten the lifetime.
• Note that storing Li-Ion batteries at high temperature dramatically reduces its capacity. For example
storage around +60°C reduces capacity with 20% in less than a month, permanently.
• Set the handset screen saver to the Black also in call option. The screen goes black and the backlight is
turned off. In addition, the backlight is turned off when the handset is in call. This helps extend battery
life especially when the user is on an extended call. See
• The handset can be configured to switch off when placed in the charger. When removed from the
charger the handset switches on automatically. See
• If the charger will not be used for a longer period of time, remove the power adapter to the charger.
• Do not put the handset in charger if no charging is needed.
