I see duplicate
entries in my
downloaded
directory.
• If you see duplicate directory entries,
you can delete them manually. Another
option is to download again either your
SIM card or phone memory, but not
both.
Some of my cell
phone contacts were
not imported to my
IS8151/IS8251.
• Try copying the contacts from your
SIM card to your cell phone memory
first, then download from your phone
memory. If that doesn’t work, try
copying the contacts from your cell
phone memory to your SIM card, then
download from your SIM card. For more
information on how to transfer contacts
between your SIM card and your phone
memory, refer to the user’s manual of
your cell phone.
Can the IS8151/
IS8251 help the poor
cell phone reception
in my house?
• If your cell phone has poor reception
in your home, the IS8151/IS8251 cannot
improve the reception. However, if
you have a location in your house with
better reception, you can leave your
cell phone in that location while you use
IS8151/IS8251 cell line. In order for this to
work, the cell phone must be within 15
feet of the telephone base for optimal
performance.
My telephone does
not work at all.
Make sure the telephone base is installed
properly, and battery is installed and
charged correctly. For optimum daily
performance, return the handset to the
telephone base after use.
The display shows
No home line. I
cannot hear the dial
tone.
Disconnect the telephone line cord from
your telephone and connect it to another
telephone. If there is no dial tone on that
other telephone either, then the telephone
line cord may be defective. Try installing a
new telephone line cord.
If changing the telephone line cord does
not help, the wall jack (or the wiring to this
wall jack) may be defective. Contact your
telephone service provider.
You may be using a new cable or VoIP
service, the existing telephone jacks in your
home may no longer work. Contact your
service provider for solutions.
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 shows
To register HS, See
manual.. The handset
does not work at all.
The handset is deregistered from the
telephone base. Follow the steps in Register
a handset to register the handset back to the
telephone base.
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 noise on the
cordless handset
and the keys do not
work.
Make sure the telephone line cord is
plugged in securely.
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.
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.
The telephone does
not receive caller
ID or the telephone
does not show
caller ID during call
waiting.
Caller ID is a subscription service. You
must subscribe to this service from your
telephone service provider for this feature
to work on your telephone.
Both your and the caller’s telephone service
providers must use equipment compatible
with the caller ID service.
The caller may not be calling from an area
which supports caller ID.
The caller ID information displays after the
first or second ring.
The display shows
Out of range or no
pwr at base.
The handset may be out of range. Move it
closer to the telephone base.
Make sure the power cord is securely
plugged into the telephone base. Use a
working electrical outlet not controlled by a
wall switch.
I cannot hear any
instruction from
the handset when
I try to record, play
or delete my own
announcement.
The handset does not have a speakerphone.
When recording, playing or deleting your
own announcement, the instructions are
announced through the handset receiver.
Make sure you place the handset receiver
close to your ear.
The outgoing
announcement is not
clear.
When recording the announcement, make
sure you speak in a normal tone of voice
towards the microphone of the handset.
Make sure there is no background noise
when recording.
