CHARGING & COMMUNICATION
1.2.1.
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 computer.
You may use the Snap-on USB Charging Cable or Charging Cradle along with a power
adapter to charge the mobile computer.
Main battery: The main battery powers the mobile computer to work. It takes approximately 4 hours to charge
an empty main battery to full. 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
computer 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.
It is recommended to charge the battery at room temperature (18°C to 25°C) for optimal performance.
Battery charging stops when ambient temperature drops below 0°C or exceeds 40°C.
Operation on Battery Power
When 802.11b/g/n, GSM/GPRS/EDGE/WCDMA/UMTS/HSDPA/HSUPA/HSPA+, Bluetooth v4.0 & v2.1+EDR and
GPS are all enabled on battery power, the main battery level will drop down substantially. Prolonged use of the
display and continued scanning of barcodes will also affect battery level.
In order to prevent system shut down after the battery is drained out, we suggest that you keep a fresh battery
for replacement at all times, or connect the mobile computer to an external power.
