My deskset doesn’t work at all.

•Make sure the power cord is securely plugged in.

•Make sure you plug the telephone line cord securely and firmly into the main telephone base and the telephone wall jack.

•Reset the deskset. Unplug the electrical power. Wait for approximately 15 seconds, then plug it back in. Allow up to one minute for the deskset

to reset.

•Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless devices. Try installing your phone as far away as possible from these types of electronic devices.

•You may need to purchase a backup battery to make the deskset work in the event of a power failure. Please refer to Backup battery installation on page 6 and Backup battery charging on page 7 in this user’s manual.

I cannot get a dial tone from the corded handset.

•Try all the suggestions above.

•Make sure you plug the handset cord securely and firmly into the handset jack on the deskset and the corded handset.

•Your line cord might be malfunctioning. Try installing a new line cord.

I cannot dial out.

•Try all the suggestions above.

•Make sure you have a dial tone before dialing. The corded handset might take a second or two to connect the deskset and produce a dial tone. This is normal. Wait an extra second before dialing.

•Eliminate any background noise. Noise from a television, radio or other appliances might cause the telephone to not dial out properly. If you cannot eliminate the background noise, first try muting the corded handset before dialing, or dialing from another room with less background noise.

•If the other telephones in your building are having the same problem, contact your telephone service provider.
