• Use only the supplied AC adapters. Be sure to use the proper adapter
for the base and any chargers.
• Do not place the power cord where it creates a trip hazard or where it
could become chafed and create a fire or electrical hazard.
• Do not place the base in direct sunlight or subject it to high

and about 7 days of standby time. For best results, return the handset
to the charger after each call to keep it fully charged.
• When the battery gets too low, the handset shows a low battery alert.
If you hear a strange beep during a call, check the display: if you see
the low battery alert, finish your conversation as quickly as possible
and return the handset to the charger. If the handset is in standby,
none of the keys will operate.
