The batteries are charged in both the handset and the base unit. It should be
noted that the spare battery charging port on the base unit provides a "trickle
charge" that charges the battery at a slower rate than through the handset.
If the power supply fails, the optional spare battery in the spare battery
charger will power the handset (available talk-time depends on how much
charge remains in the battery). The base phone continues to function without
the handset in handsfree mode even if the power supply fails and the spare
battery is discharged or not available.

Environmental considerations

The following environmental procedures should be followed.
Environmental Performance
Depending on the environmental conditions, the range of the M2616CT may
be reduced. Steel girders and concrete walls can limit the range of the cordless
telephone. Line of site conditions provide a maximum range of 150 feet.
Some microwave towers and other products that sent out 900MHz
frequencies can cause clipping when the handset is in use. A manual radio
frequency (RF) channel selection described below prevents interference with
other 900 MHz devices.
The M2616CT uses 900 MHz narrowband technology to deliver digital RF
signals from the M2616CT base to the handset. Twenty 900 MHz narrow
band channels have been allocated to the handset. When the handset is lifted
from the base the RF deck in the base scans the 20 channels for a clear channel
to use. RF channels can also be manually selected using key 14 on the base.
