Troubleshooting
Do not install this phone near a microwave oven or on the same 
electrical outlet. You may experience decreased performance 
while the microwave oven is operating.
If you plug your phone in with a modem or a surge protector, 
plug the phone (or modem/surge protector) into a different 
location. If this does not solve the problem, relocate your phone 
or modem farther apart from one another, or use a different 
surge protector.
Move your phone to a higher location. The phone may have 
better reception in a high area.
If other phones in your home are having the same problem, 
contact your telephone service provider (charges may apply).
I experience poor sound quality when using the handset 
speakerphone. 
For increased sound quality while using the handset 
speakerphone, place the handset on a flat surface with the dial 
pad facing up.
When using a speakerphone, controlling background noise in 
your environment is essential. While you are listening to your 
party, press MUTE/DELETE to temporarily turn your microphone 
off. When it is your turn to speak, remember to press  
MUTE/DELETE again to turn the microphone on.
Excessive background noise will cause a speakerphone to fade 
in and out. Try controlling the background noise by turning off 
and audio devices near the speakerphone. Also, try to avoid 
interrupting the person at the other end of the conversation 
while they are speaking. If background noise cannot be 
controlled, you should terminate speakerphone operation and 
return to normal handset mode.
My cordless handset does not ring when I receive a call.
Make sure that the ringer is not off. Refer to Ringer volume in 
the TL86103 user’s manual provided with your telephone.
