The cell phone
reception in my
house is poor
and I cannot
connect it to
my DS6771.
If there is a location in
your house with better
reception, you can leave
your cell phone at that
location while you use
the DS6771 cell line. In
order for this to work, the
telephone base must be
within 15 feet of the cell
phone.
The display
shows Low
battery.
Place the handset in
the telephone base or
charger for charging.
The battery
does not
charge in the
handset or the
handset battery
does not
accept charge.
Make sure the handset is
placed in the telephone
base or charger
correctly.
If the battery is
completely depleted,
charge the battery for at
least 30 minutes before
use.
You may need to
purchase a new battery.
