My headset doesn’t work at all.

•Make sure the power cord is securely plugged in.

•Make sure the battery is securely installed in the cordless headset.

•Make sure the telephone line cord is securely and firmly plugged into the headset or telephone base and the telephone wall jack.

•Charge the battery in the cordless headset for at least 6 hours. For optimum daily performance, return the cordless headset to its charger when not in use.

•Reset the headset. Power off the headset and then power it on.

•Reset the headset base or charger. Unplug the unit’s electrical power. Wait for approximately 15 seconds, then plug it back in. Allow up to one minute for the cordless headset and headset base or charger to reset.

•You may need a new battery. Please refer to page 7 of this user’s manual.

I cannot get a dial tone.

•Try all the suggestions above.

•Move the cordless headset closer to the headset or telephone base. You might have moved out of range.

•If the previous suggestions do not work, disconnect the headset or telephone base from the telephone jack and connect a different phone. If there is no dial tone on that phone either, the problem is in your wiring or telephone service. Contact your telephone service provider.

•Your telephone line cord might be defective. Try installing a new telephone line cord.
