•    Make sure that the ringer is not turned off. Refer to the section(s) on 

ringer selection in this user’s manual.

•    Make sure the telephone line cord is plugged securely into the base 

unit and the telephone jack. Make sure the power cord is securely 

plugged in.

•   The cordless handset may be too far from the base unit.
•    Charge the battery in the cordless handset for at least 16 hours. For 

optimum daily performance, return the cordless handset to its base 

when not in use.

•    You may have too many extension phones on your telephone line to 

allow all of them to ring simultaneously. Try unplugging some of the 

other phones.

•    The layout of your home or office might be limiting the operating 

range. Try moving the base to another location, preferably on an 

upper floor.

•    If the other phones in your home are having the same problem, the 

problem is in your wiring or local service. Contact your local tele-

phone company (charges may apply).

•    Test a working phone at the phone jack. If another phone has the 

same problem, the problem is the phone jack. Contact your local 

telephone company (charges may apply).

•    Other electronic products can cause interference with your cordless 

phone. Try installing your phone as far away as possible from elec-

tronic devices: wireless routers, radios, radio towers, pager towers, 

cell phones, intercoms, room monitors, televisions, personal comput-

ers, kitchen appliances and other cordless phones.

•   Your line cord might be malfunctioning. Try installing a new line cord.
•  Re-install the battery pack, and place cordless handset in base char-

ger.

•  Wait for the cordless handset to re-establish its connection with the 

base. To be safe, allow up to one minute for this to take place.

•  Other electronic products can cause interference with your cord-

less phone. Try installing your phone as far away from the following 

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 nor-

mal to experience static on your phone while the microwave oven 

is operating. Do not install this phone in the same outlet or near the 

microwave oven.

•  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.
