Main Power
The HT630 is powered by a rechargeable 3.7V 900mAH Lithium-Ion battery pack. The
main battery should be sufcient for daily operation up to 10 hours (based on 1 bar
code scan every 5 seconds). However, since actual operation requirements may vary,
it is possible to get a shorter result than the estimated operating times.
Backup Power
A Lithium battery is used as the secondary power source to back up the data on the
HT630. The RTC (real time clock chip) and RAM memory also help to prevent data
loss.
Normally, the HT630 gets power from the main battery to back up the RTC and RAM.
This also puts the backup battery in standby mode. When the main battery is removed
or below the required level to back up the RAM and RTC properly, the power circuit of
the HT630 automatically switches to the backup battery for power.
It is recommended to always keep the main battery charged. If the main battery loses
charge, the backup battery is capable of storing data for up to 6 months.
As long as the main battery is charged, you will not have to replace the backup
battery. If you do replace the backup battery, all data stored on the device will be lost.
All data must be backed up before replacing the backup battery.
