My telephone does not work at all.
•Make sure the battery is installed and charged correctly. For optimum daily performance, return the handset to the telephone base after use.
•Make sure the power adapter is securely plugged into an outlet not controlled by a wall switch.
•Make sure the telephone line cord is plugged firmly into the telephone base and the wall jack.
•Unplug the electrical power to the telephone base. Wait for approximately 15 seconds, then plug it back in. Allow up to one minute for the cordless handset and telephone base to synchronize.
•Charge the battery in the handset for up to 10 hours.
•If the battery is completely depleted, it may take up to 30 minutes to charge the handset before LOW BATTERY appears on the screen.
•Remove and install the battery again. If that still does not work, it may be necessary to purchase a new battery.
•Disconnect the telephone base from the telephone wall jack and plug in a working telephone. If the other telephone does not work, the problem is probably in the wiring or local telephone service. Contact your telephone service provider.

•Make sure the telephone line cord is plugged firmly into the telephone base and the wall jack.
•Disconnect the telephone line cord from your telephone and connect it 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. Contact your telephone service provider.
