Troubleshooting

•  Other electronic products can cause 

interference with your cordless phone. Try 
installing your phone as far away from the 
following electronic devices as possible: 
television sets, VCRs, or other cordless  
telephones.

•  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 your phone is plugged in with a modem or 

surge protector, plug the phone (or modem/
surge protector) into a different location. 
If this doesn't solve the problem, re-locate 
your phone or modem farther apart from one 
another, or use a different surge protector.

•  Relocate your telephone base to a higher 

location. The phone will have better 
reception when not installed in a low area.

I’m using
