My phone 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 16 hours.
For optimum daily performance, return the cordless handset to the
charger when not in use.
If the battery is depleted, it might take approximately 10 minutes
to charge the handset.
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 Handset
battery installation and charging in this user’s manual.
The display shows No line. I cannot get a dial tone.
First try all the suggestions 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 SB67138/SB67138/
SB67158 telephone, or contact your telephone service provider contact your telephone service provider
(charges may apply).
