• Refer to the user’s manual of your
Bluetooth enabled cell phone or
headset for more information about
how that device uses Bluetooth
connectivity.
• Bluetooth wireless technology
operates within a short range (a
maximum of approximately 15 feet)
from the telephone base. Keep
connected cell phones and headsets
within this range.
• If your cell phone has poor reception
in your home, the IS8128/IS8128-2/
IS8128-3/IS8128-4/IS8128-5/IS8128-
11/IS8128-21/IS8128-31/IS8128-
41/IS8128-51 cannot improve the
reception. However, if there is a
location in your house with better
reception, you can leave your cell
phone at that location while you
use the IS8128/IS8128-2/IS8128-
3/IS8128-4/IS8128-5/IS8128-11/
IS8128-21/IS8128-31/IS8128-41/
IS8128-51 cell line. For optimal
performance, the cell phone must
be within 15 feet of the telephone
base.
• If you experience poor sound quality,
it may be caused by the distance
between your cell phone and the
telephone base. To improve the
performance, place your cell phone
closer to the telephone base (within
15 feet) and make sure that there are
no physical obstacles such as large
furniture or thick wall in between.
• Charge your cell phone while it is
connected to the telephone base.
Your cell phone’s battery discharges
faster while it is connected to the
telephone base via Bluetooth
wireless technology.
• Monitor your cell phone’s usage,
because minutes may be deducted
from your cellular plan for the
duration of all cell calls, depending
on the terms of your plan.
