For more detailed instructions, refer to the online Complete user’s

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 may take approximately 30 minutes to 
charge the handset before it shows Low battery. See page 6 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 pages 6-8.
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 CL82115/CL82215/
CL82315/CL82415/CL82465/CL82515 telephone, or contact your 
telephone service provider (charges may apply).
