Battery low warning
If the 
 symbol is ashing, you will 
need to recharge your handset before 
using it.
If the battery icon is ashing and 
scrolling digits 
 the battery is 
very low and you will need to charge 
it for 24 hours before use to ensure 
maximum battery performance.
Battery performance
To keep your batteries in the best 
condition, leave the handset off the 
base for a few hours at a time (after 
the initial 24 hour charge).
New NiMH batteries do not reach 
full capacity until they have been in 
normal use for several days. Running 
the batteries right down at least once 
a week will help them last as long  
as possible.
IMPORTANT
Only use the power supply and 
telephone line cord supplied with 
your BT Studio Plus 5100 otherwise 
the telephone may not work.
Under no circumstances use 
non-rechargeable batteries. Only 
use NiMH rechargeable batteries 
with a capacity of 500mAh. Using 
inappropriate batteries will invalidate 
your guarantee and may damage 
the telephone.
The charge capacity of rechargeable 
batteries will reduce with time as 
they wear out, so reducing the 
talk/standby time of the handset. 
Eventually they will need to be 
replaced. New batteries can be 
obtained from the BT Studio 
Helpline 0800 218 2182*.
3.  Place the handset on the base to charge the batteries for 
at least 24 hours. 
  The main handset is pre-registered to the base as Handset 1. 
This is shown on the display. When the handset is fully charged 
the display shows the 
 symbol.
4.  After 24 hours plug the telephone line cord into the telephone 
wall socket.
Note: If you ever need to remove the batteries, simply slide open 
the battery compartment cover and using the nger holes grip 
the batteries and pull them out.
