My telephone 
does not work 
at all
• Make sure the power cord is securely plugged in.
• Make  sure  the  battery  is  installed  and  charged  correctly 
(page 7).
•  Make sure the telephone line cord is plugged firmly into the 
telephone base and the telephone wall jack.
•  Charge the battery in the cordless handset for at least 16 
hours. For optimum daily performance, return the cordless 
handset to the charger when not in use.
•  Reset  the  base.  Unplug  the  telephone’s  electrical  power. 
Wait  for  approximately  15  seconds,  then  plug  it  back  in. 
Allow up to one minute for the cordless handset and base 
to reset.
•  You may need to  purchase a new battery, please refer to 
page 7 of this user’s manual.
•  Disconnect the telephone base from the modular jack and 
plug in  a  working telephone. If it still does not  work, the 
problem is probably in the wiring or the local service. Call 
the local telephone company.
I cannot get a 
dial tone
• First try all the suggestions above.
• Move  the  cordless  handset  closer  to  the  telephone  base. 
You might have moved out of range.
• Your line cord might be malfunctioning. Try installing a new 
line cord.
•  If  the  previous  suggestions  don’t  work,  disconnect  the 
telephone  base  from  the  telephone  jack  and  connect  a 
different  telephone.  If  there  is  no  dial  tone  on  that  tele-
phone either, the problem is in your wiring or local service. 
Contact your local telephone company.
I cannot dial 
out
• First try all the suggestions above.
•  Make sure you have a 
dial tone before dialing. The cordless 
handset  may take a  second or  two to find the telephone 
base and produce a dial tone. This is normal. Wait an extra 
second before dialing.
•  Make sure your telephone is set to the correct dial mode 
for the type of service that you have (pulse or touch tone). 
Refer  to  the  Base  settings  section  of  this  user’s  manual 
(page 13) to set the dial mode.
