For customer service, or to purchase accessories or replacement parts, visit 
our website at www.telephones.att.com, or call 1 (800) 222-3111

My telephone 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.
If the battery is depleted, charge the handset for at least 30 minutes 
before you use it. Refer to Battery charging on page 8 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 
on page 7.
I cannot get a dial tone.
First try all of the suggestions above.
Move the cordless handset closer to the telephone base. You might have 
moved out of range.
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, then
the telephone line cord may be defective: try installing 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 EL51103/EL51103/
EL51203/EL51253/EL51303/EL51353/EL51403/EL51453/EL51503 
telephone, or
contact your telephone service provider (charges may apply).
