1.2. CHARGING & COMMUNICATION
1.2.1. CHARGE HANDY TERMINAL
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 handy terminal.
You may use the Direct Cable with a power adapter to charge the handy terminal.
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 a supplied Direct
Cable because the voltage and amperage the computer provides is lower than in the case of
using a normal charging method.
CHARGING T
IME
Main battery: The main battery powers the handy terminal 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 maintainedġfor at least 30 minutes.
Backup battery: The backup battery is mounted on the main board. Its role is to
temporarily keep the handy terminal 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.
CHARGING T
EMPERATURE
It is recommended to charge the battery at room temperature (18°C to 25°C) for optimal
performance.
Please note that battery charging stops when ambient temperature drops below 0°C or
exceeds 40°C.
OPERATION ON BATTERY POWER
When 802.11a/b/g/n, GSM/GPRS/EDGE/WCDMA/UMTS/HSDPA/HSUPA/HSPA+/LTE,
Bluetooth v4.1 & 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 from shutting down after the battery is drained out, we suggest
that you keep a fresh battery for replacement at all times, or connect the handy terminal to
an external power.
