CHARGING & COMMUNICATION
1.2.1. CHARGE MOBILE POS
The main battery may not be charged to full for shipment. When you first receive the kit package,
you will need to charge the main battery to full before using the mobile POS. You may use the
Snap-on Charging Cable or Charging Cradle along with a power adapter to charge the mobile
POS.
Your device can be charged as well when connected to a computer via USB cable; however,
charging from a USB port on a computer is slower than charging using the Snap-on Charging
Cable/Charging Cradle (all powered by the AC power adaptor).
CHARGING TIME
Main battery:
The main battery powers the mobile POS to work. It takes approximately 4 hours to charge
an empty main battery to full. For the first time charging the main battery, please charge it for
at least 8 to 12 hours. The charging LED above the screen (located on the right) will light up
in red while charging and will turn green when charging is complete.
When the main battery is removed, RTC retention will be maintained for at least 30 minutes.
Backup battery:
The backup battery is mounted on the main board. Its role is to temporarily keep the mobile
POS in suspension when the main battery is drained out so data in DRAM will be retained.
The backup battery takes approximately 3.5 hours to charge to full by the main battery or
power adapter.
