Introduction
Hand-held computers are used in the distribution sales
marketplace to perform a wide variety of tasks. The handheld computers are rugged for use in harsh environments
such as vehicles, warehouses, factories, and retail stores.
Other specialized applications such as utility companies use
them to record meter readings.
These units are battery-operated, making them extremely
portable and well suited to route industries such as beverage, bakery, snack and dairy distributors. Programs or data
can be loaded (or “downloaded”) into the hand-held computer from a PC or mainframe. The keyboard allows manual
entries.
The hand-held computer typically contains a database with
customer and product information. It performs calculations
based on product movement, sends information to a printer,
and is often used to send (upload) data to a host (larger)
computer.

should not remove the main battery pack unless you
are replacing it.
" the second method of protection for data retention is
the internal capacitor. This internal capacitor retains
memory for only 5 minutes. It is intended only for
short time periods like when you are changing the
main battery pack.
" a backup lithium battery that should only be de-
pended upon when the main battery pack is removed
or completely dead and the internal capacitor has
been exhausted. Although the lithium battery has a
life of 10 days, you should not depend on this for long
periods of time. Each time you use it you deplete its
energy and when fully used you must send your handheld to an authorized Customer Support Center for
replacement of the lithium cell.
It is very important that you not ignore the first signs of
low battery conditions.
Optional Memory Card
If your hand-held computer came with an un-installed
memory card, make sure it has a battery in it (see the
Maintenance section of this manual) before installing the
card.
1. Use a small coin or flatblade screwdriver to remove
the endcap.
4500 Hand-Held Computer User’s Guide 2-11
Page 30
Operation SECTION 2
2. Hold the hand-held computer in a vertical position
with the endcap opening up.
3. Gently fit the memory card into the wide slot. Make
sure the shutter goes into the slot first, and that the
shutter and the display on the hand-held computer
are facing the same direction, such as up or to your
left. The backup battery contained in the memory card
can be replaced by you when needed. The procedures
for doing that are described in Section Four,
Memory Card Battery Replacement, page 4-4.
4. Allow the memory card to drop into place.
5. Press firmly on the card to seat it inside the computer
(you can feel it make solid contact).
6. Reinstall the endcap. Do not overtighten screws.

Peripheral Endcap
A 9-pin standard scanner interface can be ordered as part of
the peripheral endcap. The 15-pin RS-232 connector is not
standard and therefore may require special cables for connection to various peripherals like printers and external
modems. For product direction regarding this, contact your
sales team or Customer Support Center. The peripheral
endcap has a phone jack for units that are equipped with
an optional internal modem.
Peripheral Endcap Installation
Use a small coin or flatblade screwdriver to remove the endcap. Carefully align the two 10-pin connectors on the peripheral endcap to the mating connectors in the hand-held
computer. Press together gently and tighten both screws.
Connections

Routine Operation
Daily
Hand-held computers are designed to work with you
throughout the day, without special attention. The application program (which is designed specifically for your type of
business) will guide you in making entries, printing receipts
and reports, and in performing other routine tasks.
The main NiCd battery pack is being charged every time it
is placed into a charging device. To get the longest service
from your NiCd batteries, use your hand-held computer by
itself, relying on the rechargeable battery pack for power.
Your hand-held computer will display when it is necessary
to place it on a charger (or replace in the case of alkaline

batteries). When your hand-held computer goes into a low
battery condition, place it in a charging source (i.e. printer,
modem, dock etc.) and continue to operate without fear of
losing your data.
When placed in a charging source the design allows for bypassing the main battery pack and powering your handheld computer directly from the charge source. The backup
capacitor and lithium battery, are used only when in low
battery and not connected to a charge source.
Here are some examples of charging sources:
" fixed mount printers (models 4810, 4815, or 4820)
" portable printers (models 4810, 4810C, 4815, or 4820)
connected to an external power source
" multidock (model 4960)
" single dock (model 4950)
" selected modems (check modem specifications)
LOW BATTERY (condition)
This message displays briefly to warn you that the batteries are low. You should recharge the NiCd battery pack or
replace the alkaline cells.
After the LOW BATTERY message first displays, it is to
your benefit for safe operations to recharge (NiCd only) as
soon as possible. When using alkaline cells you should replace soon after seeing
LOW BATTERY display. Refer back to the Memory
Protection section page 2-11 for a complete description of
how your hand-held is designed to avoid data loss.
As your battery pack becomes depleted the LOW
BATTERY message will display more frequently, you
should replace the main battery pack. Your 4500 hand-held
computer with a NiCd battery pack, is designed to last
about 500 charges before it needs replacing. This number is
approximate and depends on your application, and the care
given to the battery.
4500 Hand-Held Computer User’s Guide 2-15
Page 34
Operation SECTION 2
The hand-held computer will not work (except for the LOW
BATTERY message on the display) when batteries are de-
pleted. It will operate normally when connected to peripheral devices that provides charging current.
Weak batteries should remain in the hand-held computer
until you are ready to replace or recharge them. These
weak batteries can still furnish enough power to retain
memory (data entries you have made) while minimizing the
drain on the backup power source. This practice extends the
useful life of the backup battery.
Before storing your hand-held for more than 10 days you
should upload all data to your host computer, turn your
hand-held Off, and ensure that a fully charged NiCd battery pack or fresh alkaline cells are installed in your handheld. This provides power for the hand-held computer to
maintain memory without drawing power from the lithium
backup battery.

Main Battery Care
When the hand-held computer displays LOW BATTERY, it
is time to replace the alkaline cells, or, to recharge the NiCd
battery pack.
Section 4
Maintenance
Charging
Charge the NiCd battery by connecting the hand-held computer to a peripheral device that provides a charging current such as the following equipment:
" 4960 MultiDock
" 4950 Single Dock
" 4810, 4815, or 4820 fixed-mount printers
" portable printers (models 4810, 4810C, 4815, or 4820)
connected to an external power source
" many modems also provide charging current
A complete charge of the NiCd battery pack requires 11
hours.
4500 Hand-Held Computer User’s Guide 4-1
Page 38
Maintenance SECTION 4
When a hand -held computer equipped with a NiCd battery
pack is first placed into service, it should be charged for at
least 11 hours. The same holds true whenever a replacement NiCd battery pack is first installed.
Thereafter, the NiCd battery pack normally maintains a
good charge if the hand-held computer is docked in a charging source overnight (e.g., single dock, multidock, fixedmount printer, or selected modems).
Backup Battery Replacement
Backup battery replacement requires major disassembly of
the hand-held computer, and is only performed by authorized service center personnel.
Hand Strap Replacement
You can replace a worn or damaged hand strap using a
Phillips screwdriver.
Place the hand-held computer, keyboard and display side
down, on a clean work surface. A soft cloth or newspaper
can be used to prevent scratches. Notice the two retainers.
1. Remove the two Phillips-head screws on each hand
strap retainer.
2. Pry up on the retainers with a flat tool or screwdriver.
3. Remove and discard the worn hand strap.
4. Lay the new hand strap on the hand-held computer.
Determine if new retainers are included with the replacement hand strap: if so, discard the originals and
use only the new retainers in steps 5 and 8.
5. Install one hand strap retainer. Tighten the screws.
6. Stretch the other end of the hand strap over the alignment pins at the other end of the computer.
4-2 4500 Hand-Held Computer User’s Guide
Page 39
SECTION 4 Maintenance
7. Use one hand to push the hand strap so that it does
not pull against the alignment pins. This relieves
stress on the elastic and aligns the screw holes.
8. Install the retainer on this end of the hand strap.
Tighten the screws, then release tension on the hand
strap.
Do not over tighten screws as this can damage the case.
