My phone 
doesn’t work 
at all.
•  Make sure the power cord is securely plugged in.
•  Make sure that the battery connector is securely plugged 
into the cordless handset.
•   Make sure the telephone line cord is securely and firmly 
plugged into the telephone base and the telephone wall 
jack.
•   Charge the battery in the cordless handset for at least 
16 hours. For optimum daily performance, return the 
cordless handset to the telephone base or charger when 
not in use.
•   Reset the telephone base. Unplug the unit’s electrical 
power. Wait for approximately 15 seconds, then plug it 
back in. Allow up to one minute for the cordless handset 
and telephone base to reset.
•  You may need to purchase a new battery, please refer 
to Battery installation and charging (pages 8-9) in this 
user’s manual.
I cannot get a 
dial tone.
•  First try all the suggestions above.
•  Move the cordless handset closer to the telephone base. 
You might have moved out of range.
•   If the previous suggestions don’t work, disconnect the 
telephone base from the telephone jack and connect to 
a different phone. If there is no dial tone on that phone 
either, the problem is in your wiring or local service. 
Contact your telephone service provider.
•  Your line cord might be malfunctioning. Try installing a 
new line cord.
I cannot dial 
out.
• First try all the suggestions above.
•  Make sure you have a 
dial tone before dialing. The cordless 
handset may take a second or two to find the telephone 
base and produce a dial tone. This is normal. Wait an extra 
second before dialing.
