MAXIMIZE BATTERY PERFORMANCE

The freedom that your cordless telephone can offer is fully dependent on the performance
of the rechargeable battery in the handset. To maximize the battery performance, follow
these guidelines:
Charge it for a full 12 hours
Before initial use of your new battery, charge it for 12 hours continuously. The proper initial
charging is very important to maximize the battery performance.
Keep the contacts clean
You can never fully recharge the battery if the contacts are dirty. Clean all the contacts -
two at the bottom of the handset and two in the base cradle - periodically. Use a clean
pencil eraser or superfine steelwool to clean the charging contacts. Avoid touching the
cabinet area of the phone, or scratches may occur.
Refresh battery
If your battery seems to need recharging more often than usual, it may have lost part of its
charging capacity. To bring back its full capacity, try "refreshing" the battery:
1. First discharge the battery by leaving the handset in TALK mode until Battery Low
indication turns on. (Disconnect the base from the telephone line, so that your line is
not busy all the time.)
2. Then charge it for 12 continuous hours.
3. Repeat the above once more. As your OS5851L-BR product use a Ni-MH battery you
are free to leave your handset in the base charger for as long as you like, without
effecting the performance of the battery life.
