I cannot dial
out.
Make sure there is a dial
tone before dialing. It is
normal if the handset
takes a second or two
to synchronize with the
telephone base before
producing a dial tone.
Wait an extra second
before dialing.
Eliminate any
background noise.
Mute the handset
before dialing, or dial
from another room in
your home with less
background noise.
The display

I cannot add
and connect
my cell phone
or headset to
the telephone
base.
Make sure you have
cellular coverage and the
Bluetooth function of your
cell phone or headset is
turned on. See the user’s
manual of your cell phone
or headset for more
information.
Make sure that the
telephone base is in
discoverable mode.
Carefully follow the pairing
instructions in this manual.
Make sure that your
Bluetooth cell phone or
headset is not connected
to any other Bluetooth
device, and is connected
to the telephone base and
active on the device list.
Turn off your cell phone or
headset, and then turn it
on again.
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.
The telephone
does not ring
when there is
an incoming
call.
Make sure the ringer
volume is not set to off.
The handset may be too
far from the telephone
base. Move it closer to
the telephone base.
My handset
beeps and is
not performing
normally.
Move the handset closer
to the telephone base. It
may be out of range.
I hear other
calls when
using the
telephone.
Disconnect the telephone
base from the telephone
wall jack. Plug in a different
telephone. If you still hear
other calls, the problem is
probably in the wiring or
telephone service. Contact
your telephone service
provider.
I hear noise on
the cordless
handset and
the keys do not
work.
Make sure the telephone
line cord is plugged in
securely.
There is
interference
during a
telephone
conversation.
My calls fade
out when
I am using
the cordless
handset.
The handset may be out
of range. Move it closer
to the telephone base.
If you subscribe to high-
speed Internet service
(DSL - digital subscriber
line) through your
telephone line, you must
install a DSL filter between
the telephone line cord
and the telephone wall
jack. The filter prevents
noise and caller ID
problems caused by DSL
interference. Contact your
DSL service provider for
more information about
DSL filters.
Appliances or other
cordless telephones
plugged into the
same circuit as the
telephone base can
cause interference. Try
moving the appliance
or telephone base to
another outlet.
The location of your
telephone base can
impact the performance
of your cordless phone.
For better reception,
install the telephone base
in a centralized location
within your home or
office, away from walls
or other obstructions.
In many environments,
elevating the telephone
base improves overall
performance.
