WARNING!

supplied. Using incorrect power 
adapters may permanently 
damage your product.
Battery performance
Rechargeable batteries 
in the Parent unit will last 
approximately 16 hours during 
normal operation or 20 hours 
when Mute is switched on. 
Please note that new batteries 
do not reach full capacity until 
they have been in normal use 
for several days.
The charge capacity of 
rechargeable batteries will 
reduce with time as they 
wear out, so reducing the 
performance time of the Parent 
unit. Eventually they will need 
to be replaced. New batteries 
can be obtained from the  
BT Digital Baby Monitor 300 
Helpline on 0800 145 6789*.
The Parent unit rechargeable 
batteries will lose charge over 
a period of time, even if 
switched off.
