Diverse 4000 Classic ~10th Edition ~ 19th September ’01 ~ 4167

Leave the handset for approx. 16 hours in the base station to charge the batteries, as they are not charged in the factory. The charging status icon flashes on the handset to indicate that the batteries are being charged.

When the batteries are almost flat a beep sounds and the display shows the empty battery icon. You will need to recharge your handset before you can use it. The various states of charge are shown below:

Batteries fully charged

Out of range?

If you go out of range of a base station for a long time while your handset is switched ON, it may take more than 20 minutes to ‘find’ the base station again when you come back within range. However, by simply switching the handset OFF for a moment, then ON again, it will find the base station within a few seconds.

Battery performance

After charging your handset batteries for the first time, subsequent charging time is approximately 4–5 hours.

Batteries and case may become warm during charging. This is normal.

Under ideal conditions, the handset batteries should give about 10 hours talktime or 200 hours standby time on a single charge. However, new NiCad 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 any BT shop or from the Diverse Helpline 08457 908070.

If you replace the handset batteries with ones that have been fully charged, the battery indicator will not show full until the next charge cycle has been completed. Charge the handset until the batteries register full again. From then on the display will be correct.
