REPLACING THE HANDSET BATTERY  
About Cordless Phone Performance  
The rechargeable NiCad battery in your cordless phone may need to be replaced  
if the handset will not function when the TALK button is pressed after recharging  
for 12 hours.  
Replacement batteries are available direct from Cobra (see accessories order form  
at the end of this booklet or call 1-773-889-3087).  
Your Cobra Intenna cordless phone uses radio transmission to communicate  
between the base and handset. It is thus subject to occasional interferenceÑstatic  
or buzzing noises, for example. These conditions may be caused by electrical  
motors on household appliances, ßuorescent lights, electrical storms and other  
sources.
