First Time to Charge the Main Battery & Backup
Battery
We would like to propose to charge the battery at least up to 16 hours for the
first time to use. While it normally only takes about 4 hours to charge the
battery after it's been drained, when charging the battery for the first time
please allow at least 16 hours. While charging the main battery the backup
battery should also be charged. Please make sure the backup battery has
been switched "ON" (this cannot be emphasized enough).
CAUTION: There is a high risk of data loss from RAM if the backup battery is
not fully charged. This can happen if the main battery has been
drained and the unit is not connected to the AC adaptor. For this
reason, it is crucial that the backup battery is switched on before
charging the main battery for the first time.
