Energy Efficiency

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
Screen Saver
• The handset can be configured to switch off when placed in the charger. When removed
from the charger the handset switches on automatically. See
when not in Call
• 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.
