1.1 BATTERY
1.1.1 MAIN BATTERY
The mobile computer is fed by a rechargeable 3.7 V/4000 mAh Li-ion battery pack. When the mobile computer is turned off, it takes approx. 5 hours to charge it to full from the power adapter (using RS-232 cable or cradle) or approx. 14 hours from the USB cable (at
500 mA).
For power-saving purpose, always turn off the backlight while working in a well-lit area.
When the backlight is on for extended periods of time, the main battery will become low sooner than expected.
The smart battery icon on the LCD screen shows the status of power consumption. There are two ways to monitor the battery charge:
Examine the level of the 4-bar battery icon on the screen
Check up the voltage level by
System Menu
(see
11
8700 Series Mobile Computer Reference Manual
1.1.2 BACKUP BATTERY
The backup battery on the main board takes the responsibility to supply power to the mobile computer when the main battery is removed or drained out. When fully charged, the 3.0 V/7 mAh rechargeable Lithium button cell helps retain data in SRAM and maintain the running of the real-time clock and calendar for at least 25 days without the main battery. In the meantime, you have to replace the main battery as soon as possible. It takes at least twenty-four hours to fully charge the backup battery. However, it is not necessary to fully charge the backup battery for the mobile computer to work.
Monitor voltage level by
System Menu
)
1.1.3 CAUTION OF LOW BATTERY CHARGE
The battery pack is the only power source for the mobile computer to work. It also charges the backup battery on the main board so the data stored in SRAM can be retained properly. Therefore when the main battery charge goes low, you need to replace the battery pack with a charged one or charge it as soon as possible. Most of all, you should upload important data on a regular basis.
Warning: Data loss may occur with SRAM during low battery condition. Always save data before running out of power or keep a fresh battery for replacement.
12
1.2 MEMORY
Chapter 1 Using mobile computer
The collected data can be sent back to a host computer immediately over wireless data connections, or stored in memory (SRAM) for a later upload. The mobile computer is equipped with a calendar chip for accurate time/date logging. When the main battery is removed or drained, the backup battery on the main board takes over to retain the contents of SRAM and keep the real-time clock and calendar running. When fully charged, it keeps said jobs up for at least 25 days.
If you want to put away the mobile computer for a couple of days, you should be aware that data loss occurs when both the main and backup batteries discharge completely.
Therefore it is necessary to upload data and files before putting away the mobile computer!
1.2.1 READ-ONLY MEMORY (ROM)
8 megabytes flash memory for storing core, OS, application programs, fonts, etc.
1.2.2 RANDOM-ACCESS MEMORY (RAM)
Options include 4 or 16 megabytes SRAM for storing data. Its contents will be retained by the backup battery.
1.2.3 SD CARD
Secure Digital (SD) card is a flash memory data storage device. High capacity memory card (microSDHC) is supported. Refer to
Inserting Battery & Memory Card
for how to
insert the microSD or microSDHC card. For more details, refer to 1.8 SD Card
.
Note: (1) When SD card is present, the card icon will appear on the screen and flash while being accessed.
(2) For an SD card that has never been used on the mobile computer, a message like “Found New SD Card” will be displayed allowing users to scan the card for memory check. If you don’t feel the need for an instant check on the memory, you can select cancellation and perform the memory check later through
System
Menu
. See

RFID tag in proximity depending on which one comes first.
Note: You cannot have 1D+2D scan engines installed on the mobile computer because they are both barcode readers.
Varying by the reader type installed, the supported symbologies or tag types are listed below:
1D CCD scan engine
1D Laser scan engine
1D Long Range Laser scan engine (LR)
2D scan engine
RFID reader
1.6.1 SYMBOLOGIES SUPPORTED
A wide variety of scan engines is available for delivering flexibility to meet different requirements. Depending on the scan engine integrated, the mobile computer is capable of scanning barcodes of a number of symbologies that are enabled by default while
running the preloaded AG runtime. Refer to 3.3.1 Reader
for functional test.
If you need to scan barcodes that are encoded in a symbology that is disabled by default in AG runtime,
FORGE Application Generator
(ForgeAG.exe) can help you configure symbology settings and reader settings. First, enable the desired symbologies in
FORGE
Application Generator
, and then download the application settings to the mobile computer.
Note: In AG or CipherNet runtime, not all of the symbologies are enabled by default.
Instead of running any of them, you can develop your own applications to control the scan engine for data collection. For details on configuring reader and symbology settings, please refer to the documentation of the software you use.

1.8 SD CARD
A SD card inserted in the mobile computer is directly accessible for user’s applications.
Yet when the mobile computer connects to the host computer via a USB cable, the SD card can work as a removable disk (USB mass storage device) as long as it is configured properly through programming or via

1.8.3 FILE NAME
A file name must follow 8.3 format (= short filenames) — at most 8 characters for filename, and at most three characters for filename extension. The following characters are unacceptable:
“ * + , : ; < = > ? | [ ]
On 8700 Series, it can only display a filename of 1 ~ 8 characters (the null character not included), and filename extension will be displayed if provided. If a file name specified is longer than eight characters, it will be truncated to eight characters.
Long filenames, at most 255 characters, are allowed when using the mobile computer equipped with SD card as a mass storage device. For example, you may have a filename “123456789.txt” created from your PC. However, when the same file is directly accessed on the mobile computer, the filename will be truncated to
“123456~1.txt”.
If a file name is not specified in ASCII characters, in order for the mobile computer to display it correctly, you may need to download a matching font file to the mobile computer first.
The file name is not case-sensitive.
