ADDITIONAL INFO
Problem Suggestion
My calls fade or cut in 
and out while I’m using 
my handset.
•  Press the CHAN button while on a call until the interference has been eliminated.
•   Other electronic products can cause interference with your cordless phone. Try installing your 
phone as far away from these types of electronic devices as possible: wireless routers, radios, 
radio  towers,  pager  towers,  cell  phones,  intercoms,  room  monitors,  televisions,  personal 
computers, kitchen appliances and other cordless phones
•   Microwaves operate on the same frequency as your phone. It is normal to experience static on 
your phone while the microwave is running. Do not install this phone in the same outlet or near 
the microwave.
•   If your phone is plugged in with a modem or surge protector, plug the phone (or modem/surge 
protector) into a different location. If this solves the problem, re-locate your phone or modem 
farther apart from one another, or use a different surge protector.
•  Relocate your phone to a higher location. The phone will get better reception not installed in a 
low area.
•   If the other phones in your home are having the issue, the problem is in your wiring or local 
service. Contact your local telephone company (charges may apply.)
The charge light is off. •  Clean the handset and base charging contact each month using a pencil eraser or cloth.
•  Make sure the power and line cords are plugged in correctly and rmly.
•   Reset the base. Unplug the unit’s electrical power. Wait for 15 seconds then plug it back in. Allow 
up to one minute for the handset and base to reset.
•   Your phone might be malfunctioning. Please refer to the Warranty section of this user’s manual 
for further instruction.
