Battery performance

Under no circumstances should non-rechargeable batteries be used. Only use the approved batteries, type: rechargeable Nickel Metal Hydride (Ni-MH); size AAA; capacity 550mAh 1.2v. Using unapproved batteries will invalidate your guarantee and may damage the telephone.

To keep your batteries in the best condition, leave the handset off the base station for a few hours at a time. (after the intial 16 hour charge).

Please note, however, that new Nickel Metal Hydride (Ni-MH) batteries do not reach their full capacity until they have been in normal use for several days.

Fully discharging the batteries at least once a week will help them last as long as possible. However, 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 Synergy Helpline 08706 058 047.

Note: Under ideal conditions, the handset batteries should give about 14 hours talktime or 350 hours standby on a single charge. Optimum times for talk and standby are only achieved when the handset batteries are fully charged.

Note

It is recommended that you do not connect the telephone line cord to the phone socket until your handset is fully charged. This will prevent the risk of the batteries discharging during a conversation, which could cause you to lose a call.
