Troubleshooting

My cordless 
handset does 
not ring when I 
receive a call.

•  Make sure that the ringer is not turned off. 

Refer to the section(s) on ringer selection 
in the manual provided with your TL92278/
TL92328/TL92378 telephone.

•  Make sure the telephone line cord is 

plugged securely into the telephone base 
and the telephone jack. Make sure the 
power cord is securely plugged in.

•  The cordless handset may be too far from 

the telephone base.

•  Charge the battery in the cordless handset 

for at least 16 hours. For optimum daily 
performance, return the cordless handset 
to its base when not in use.

•  You may have too many extension phones 

on your telephone line to allow all of them 
to ring simultaneously. Try unplugging 
some of the other phones.

•  The layout of your home or office might 

be limiting the operating range. Try moving 
the telephone base to another location, 
preferably on an upper floor.

•  If the other phones in your home are 

having the same problem, the problem is in 
your wiring or local service. Contact your 
local telephone company (charges may 
apply).

•  Test a working phone at the phone jack. If 

another phone has the same problem, the 
problem is the phone jack. Contact your 
local telephone company (charges may 
apply).
