My telephone doesn’t work at all.
Make sure the power cord is securely plugged in.
Make sure you plug the battery connector securely into the cordless handset.
Make sure you plug the telephone line cord securely and firmly into the telephone 
base and the telephone wall jack.
Charge the battery in the cordless handset for at least 10 hours. For optimum daily 
performance, return the cordless handset to the telephone base or charger when 
not in use.
If the battery is depleted, it might take approximately 30 minutes to charge the 
handset before it shows Low battery. See page 4 for details. 
Reset the telephone base. Unplug the 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 in this user’s manual on page 4.
The display shows No line. I cannot get a dial tone.
Try all the suggestions, as mentioned above.
If the previous suggestions do not work, disconnect the telephone line cord from 
your telephone and connect the telephone line cord to another telephone.
If there is no dial tone on that other telephone either, your telephone line cord 
may be defective. Install 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. Try using a different wall jack in your home 
to connect your CL82101/CL82201/CL82251/CL82301/CL82351/CL82401/
CL82451/CL82501/CL82551/CL82601 telephone, or contact your telephone 
service provider (charges may apply).
I cannot dial out.
Try all the suggestions, as mentioned above.
Make sure you have a dial tone before dialing. The cordless handset might take a 
second or two to find the telephone base and produce a dial tone. This is normal. 
Wait an extra second before dialing.
Eliminate any background noise. Noise from a television, radio or other appliances 
might cause the phone to not dial out properly. If you cannot eliminate the 
background noise, first try muting the cordless handset before dialing, or dialing 
from another room with less background noise.
If other phones in your home are having the same problem, contact your telephone 
service provider (charges might apply).
