device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference in a residential installation. This

equipment generates, uses and can radiate radio frequency energy and, if not installed

and used in accordance with the instructions, may cause harmful interference to radio

communications. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause harmful interference to radio or

television reception, which can be determined by turning the equipment off and on, the

user is encouraged to try to correct the interference by one or more of the following

measures:

 Reorient or relocate the receiving antenna.

 Increase the separation between the equipment and receiver.

 Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

 Consult the dealer or an experienced radio/TV technician for help.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following

two conditions: (1) This device may not cause harmful interference, and (2) this device

must accept any interference received, including interference that may cause undesired

operation.

Introduction

GETTING STARTED

INSTALLING HAND STRAP

The hand strap is ideal for one-handed operation, which requires safe and convenient

hold of the mobile computer.

Warning: Always make sure the hand strap is well hooked and screwed to the back

of the mobile computer before use.

When the hand strap is desired, install it to the mobile computer by following these

steps:

1) Place the mobile computer face down on a flat and clean surface.

2) Screw one end of the hand strap to the back of the mobile computer.

3) Insert and hook the other end of the hand strap to the bottom of the mobile

computer.

4) Make sure the hand strap is securely attached to the mobile computer.

Figure 2: Installing the Hand Strap

6

8500 Series Mobile Computer Reference Manual

INSTALLING PISTOL GRIP

This contoured pistol grip enables intuitive trigger-and-scan operation, which is very

helpful in scan intensive applications. When the pistol grip is desired, install it to the

mobile computer by following these steps:

1) Place the mobile computer face down on a flat and clean surface.

2) Remove the shield-like cover on the back of the mobile computer by unscrewing.

If the hand strap is installed, remove it first. Keep the cover and screws for future use

when the pistol grip is not desired.

3) Connect the power connector from the pistol grip to the receptacle on the mobile

computer.

4) Screw the pistol grip to the shield-like cover.

5) Make sure all screws are tightened up.

6) Turn on the mobile computer and test the trigger.

Introduction

INSERTING BATTERY

For shipping and storage purposes, save the mobile computer and the main battery in

separate packages. This will keep both batteries in good condition for future use.

Note: Any improper handling may reduce the battery life.

1) Hold the mobile computer still as shown below.

2) Slide the battery pack into the battery compartment at a proper angle (30°~45°) so

that the metal contacts of the battery are met with the charging contacts inside the

compartment. Make sure that the battery is snugly fit into the compartment.

3) Slide the battery latch to lock the battery in the compartment.

Note: For a new battery, make sure it is fully charged before use. Always prepare a

spare battery pack, especially when you are on the road.

Figure 4: Installing the Main Battery

8500 Series Mobile Computer Reference Manual

INITIAL CHARGING

The main and backup batteries may not be charged to full for shipment. When you first

receive the package, you will need to charge batteries to full before using the mobile

computer. You may use a cradle or charger to charge the Mobile Computer or spare

batteries. Refer to

1.7 Charging & Communications.

Note: Battery charging stops when the temperature drops below 0°C or exceeds 40°C. It

is recommended to charge the battery at room temperature (18°C to 25°C) for

optimal performance. For initial charging, it takes approximately 4 hours to charge

the battery to full.

Because the internal backup battery is constantly charged from the main battery, the

initial charging requires inserting the battery pack to the mobile computer and then

seating the mobile computer in the cradle for charging. This will have both the main and

backup batteries charged at the same time. It takes at least 24 hours to fully charge the

backup battery. However, it is not necessary to fully charge the backup battery for the

mobile computer to work.

Note: In order to charge the backup battery to full, you must insert the main battery and

leave it for at least 24 hours, whether the mobile computer is in use or not.

SETTING LOCAL TIME

If you need to set your local time, go to System Menu | 2. Settings | 1. Clock. Refer

to

3.2.1 Clock.

POWER MANAGEMENT

For any portable device, power management is a critical issue especially when you are on

the road. Below are some tips to help you save battery power.

Warning: Using backlight, wireless connectivity, and peripherals while on battery

power will substantially reduce battery power.

 To speed up charging the mobile computer, turn off the mobile computer and seat it

in the cradle.

 Bring a second battery pack on the road.

 Stop wireless connectivity, Bluetooth or 802.11b/g that is not in use.

 Go to System Menu | 2. Settings | 2. Backlight Period, and configure backlight

period and luminosity. Refer to

3.2.2 Backlight Period.

 Go to System Menu | 2. Settings | 3. Auto Off, and configure the amount of idle

time that must pass before the system will shut down automatically. Refer to

3.2.3

1.1 BATTERY

1.1.1 MAIN BATTERY

The mobile computer is powered by a rechargeable 3.7 V/4000 mAh Li-ion battery pack,

and it takes approx. four hours to charge it to full.

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 a low battery charge or discharged battery from the screen.

 Examine the level of the 4-bar battery icon

 Monitor voltage level (see 3.5 Power)

Chapter 1

USING 8500 MOBILE COMPUTER

8500 Series Mobile Computer Reference Manual

1.1.2 BACKUP BATTERY

The backup battery on the main board takes charge 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 one week 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 (see 3.5 Power)

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 that 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.
