6220 Hand-Held Computer User’s Guide 1-11
General Information SECTION 1
Backlight and Display Contrast
Adjustment
Your hand-held computer display contains a backlight for
operating in dark conditions. Although it greatly improves
operating in dark conditions it does shorten your battery
run time. Your hand-held computer will shut the backlight
off when there is no activity. Section 2 explains how to turn
on the backlight and adjust the contrast of the display.
Battery
Main Battery Pack
This hand-held computer uses a rechargeable lithium ion
(Li Ion) battery pack.
Your hand-held computer senses the capacity (run time) left
in your main battery pack before it goes into a low battery
condition.
This user’s guide may occasionally use the term “cycles”
when presenting rechargeable battery instructions. Cycles
are the number of times the rechargeable battery pack can
be drained, and recharged during the life of the battery. The
rechargeable battery design should give you many cycles of
use.
When you press the ON key to suspend operation, your
hand-held computer does not completely turn itself off. The
main battery pack is protecting data and if the pack is completely charged it will protect the data for about six days.
Backup Battery
When your hand-held computer goes into shutdown mode
because of low battery condition, the data is protected by
the backup battery. Your hand-held computer will not accept data or process transactions until you deal with the
1-12 6220 Hand-Held Computer User’s Guide
SECTION 1 General Information
low battery condition. A fully charged backup battery will
save data for about 10 hours.
Your hand-held computer contains a rechargeable NiCd
backup battery. Most of the time the backup battery is in a
rest mode, ready to take over data protection instantly
when the main battery cells are in low condition or out of
the hand-held computer.
If you are storing your hand-held computer for a long period
remove all batteries. This will prevent any damage that
could occur to your hand-held computer should the cells develop a leak.
Memory
This hand-held computer design uses these types of
memory:
" Main Memory DRAM
" Flash ROM
" PC Cards
Main Memory
Your main memory DRAM options are 8 or 16 Megabytes.
Main memory is ordered at the time this product was purchased. You can upgrade to more memory but you must
send your hand-held computer to your Customer Support
Center. The main memory requires batteries in your handheld computer to protect it. This memory is protected by the
backup battery during low main battery conditions or when
the main battery pack is removed.
Flash ROM
Your hand-held computer has 2 MB of flash ROM. This
stores the BIOS and DOS firmware. Applications stored in
flash ROM are copied into DRAM for execution. Flash does
not require a battery in your hand-held computer to maintain its contents.
6220 Hand-Held Computer User’s Guide 1-13
General Information SECTION 1
PC Cards
Different brands of PC cards can be used in your hand-held
computer. Memory cards are available in a variety of sizes
and types. Check with your Sales Representative or System
Engineer for specific options.
Your hand-held computer provides two PC memory card
slots. These slots can be used for storage of data, much like
a floppy disk drive on a PC. PC card slots can also be used
for modems, radios, and other options as they become available.
You can use a Type II card in each drive at the same time. If
using a Type III card, it only works in drive A (closest to
display). However, you cannot use a Type III and a Type II
card at the same time. Type III cards include some types of
disk drives and radios.

SECTION 1 General Information
Reset Switch
In the rare event that your hand-held computer fails to respond to your input, it may be necessary to “reset.” Avoid
using the reset switch as this increases the chances that
data will be lost. Only use the reset switch after trying all
other solutions. Refer to the Troubleshooting Table in Section 4 and try those solutions before resetting your computer.
The Reset switch access is located behind the 15-pin connector. To access use a straightened large paper clip, insert
one end in the reset switch hole.

Introduction
This section tells you how to:
" Install the main and backup batteries
" “Power-up” your hand-held computer
" Install optional memory cards
" Connect to peripheral devices
Getting Started
Unpack your 6220 Hand-Held Computer and inspect it for
signs of physical damage that may have occurred in shipment or storage.
Fully charge the batteries in your hand-held computer before using them. Put the computer on a charging source for
at least 10 hours to ensure that the backup battery and
main battery pack are completely charged.
When you start using your hand-held computer or any time
that all power has been completely removed, you are “cold
booting” your hand-held computer. The method you use depends on your application.
For example you may download (transfer from the host
computer to your hand-held computer) the application and
data. Or, you may use PC cards to load the application and
data.
