Disposing of nickel-cadmium batteries
Nickel-cadmium batteries contain chemically active
materials that are hazardous to the environment;
therefore, they must be disposed of properly. Never
attempt to incinerate a nickel-cadmium battery; doing
so could cause it to explode. Telxon urges you to
contact the Environmental Protection Agency, the
Department of Natural Resources, a local hazardous
waste disposal agency, or the Telxon Customer
Support Center for assistance prior to disposing of
your nickel-cadmium batteries.

Overview of the battery charger
The 1130/1134 Battery Charger is an accessory for the
PTC-1130/1134 series of pen-based hand-held
computers. These portable computers collect, store,
and transmit data.
The battery charger provides a quick way to recharge
the battery packs that provide power for all
PTC-1130/1134 models. One charger can hold up to
four battery packs at a time.
4
!
Only nickel-cadmium battery packs
that have been designed for use in
a PTC-1130/1134 model can be recharged by the charger. Do not attempt to recharge other types of rechargeable batteries. Doing so
could destroy those batteries and
damage the charger.
The charger recharges a battery pack in 2 hours or
less. If more than one battery pack is in the charger,
the packs are charged one after another, starting with
the pack farthest to the left. If four packs are
installed in the charger, the first will be fully charged
after no more than 2 hours, and the fourth will be
fully charged after no more than 8 hours.
The charger senses when a battery pack is not fully
discharged and automatically adjusts the recharge
time. For example, a half-charged battery pack will be
recharged in one-half the typical recharge time. If a
fully charged battery pack is inserted into the battery
charger, it will be detected, charging will stop in 5 to
10 minutes, and the charger will go into trickle charge
mode.
The charger is also able to detect faulty battery packs
and is equipped with a cycling feature that can be
used to maintain battery pack life.
The charger draws its power from an external 18-volt,
800-mA AC power pack. The charger is designed to be
used while resting on a horizontal surface such as a
shelf or table.

Getting started
Unpacking the 1130/1134 Battery Charger
The 1130/1134 Battery Charger is shipped in a single
box containing
• an 1130/1134 Battery Charger,
• a power pack (if ordered),
• an 1130/1134 Battery Charger User’s Guide,
and
• a Guide to Maintaining NiCd Batteries.
Spare battery packs for the PTC-1130/1134, if
ordered, are shipped in a separate box.
1. Unpack the box and save the packaging in case
the charger is ever stored or shipped to Telxon for
service.
2. Check the contents of the package to make sure
you have received everything ordered.
5
If anything is missing or damaged,
notify your Telxon sales representative.
If you are using the charger outside
of the U.S. or Canada, you need a
power pack designed for a 240-volt
outlet.
3. Check the charger and accessories for shipping
damage.
Installing the battery charger
Equipment required:
• A power pack
• An electrical outlet, providing 120 volts AC in
the U.S. or Canada, within 6 feet (1.8 meters)
of the charger’s permanent location
11
Page 14
1. Place the charger on a horizontal surface in a
location where the temperature will be between
–4 degrees F (–20 degrees C) and 122 degrees F
(50 degrees C).
2. Plug the power pack’s cable into the power
connector on the side of the charger.
3. Plug the power pack into an electrical outlet.
Running the power-on self test
When you plug in the 1130/1134 Battery Charger, it
automatically performs a series of self-diagnostic
tests to ensure it is operating correctly. These tests
take approximately 10 seconds to complete.
The tests are indicated by flashing patterns of the
charger’s battery pack slot light-emitting diodes
(LEDs). If the charger passes these diagnostics, all
the LEDs, except the Power LED, turn off after
approximately 10 seconds, provided no battery packs
are in the charger.
If any LEDs other than the Power LED remain lit,
with no battery packs in the charger, the diagnostic
tests have discovered an error. Refer to the
“Troubleshooting” section on page 20 for further
information.

Recharging battery packs
7
!
Do not attempt to recharge any
battery packs other than those designed for the PTC-1130/1134. Doing
so could destroy those batteries and damage the charger.
!
Recharging a cold battery pack can
damage it. Allow any battery pack
used in below-freezing temperatures
(32 degrees F/0 degrees C or less) to
warm up to room temperature before recharging.
Figure 2. Inserting a battery pack
A battery pack can be inserted into any battery pack
slot. If it is the only pack installed, the charger will
start charging it. If a second pack is inserted to the
left of the first pack (while the first pack is being
charged), the charger will begin charging the second
pack after the first pack has been fully charged. The
left-most pack is always the next to be charged.
Inserting a battery pack
1. Hold the battery pack so the flat side is toward
the left side of the battery charger and the battery
pack contacts face down. See Figure 2.
2. Insert the battery packs, in any order, into the
slots. Make sure the battery packs are firmly
seated against the bottom of the slots.
15
Page 18
!
Do not force a battery pack into a
slot. The slots are keyed to allow a
battery pack to fit in only one way.
The battery pack slots are keyed to prevent the
battery packs from being inserted with reversed
polarity. If a battery pack is inserted incorrectly, it
will not slide all the way to the bottom of the slot.
See Table 2 for an explanation of
the LED codes.
The battery pack may grow slightly
warmer while it is charging; this is
normal.
Do not remove a battery pack from
the charger until the green
Charged LED below its slot lights.
3.Charging begins automatically. The red Charging
LED below each slot containing a battery pack
lights. Allow approximately 2 hours charging time
per battery pack. (A battery pack that is not fully
discharged will take less time to charge.)
4.When the green Charged LED below a slot lights,
the battery pack is charged and can be removed
and used.
See the table on page 25 for an interpretation of the
battery pack slot LEDs.
Removing a battery pack
Once a battery pack has been charged, it can be
removed, regardless of which slot it occupies, and
another battery pack can be inserted into this slot.
1.To remove a battery pack, grasp it and then lift it
out of the charger.
Disposing of battery packs
Nickel-cadmium battery packs are hazardous waste.
See the “Safety information” section on page 8 for
information on how to properly dispose of them.

Page 19
Cycling a battery pack
8
!
Cycle battery packs only when necessary. During cycling, each battery
pack is fully discharged and recharged three times. Your battery
packs are rated for only a certain
number of recharges, and cycling
uses up three of those recharges.
See Appendix C for an explanation
of the LED codes.
If a battery pack does not hold a
full charge after being cycled, it is
faulty and must be replaced.
Cycling reconditions battery packs that are not
holding a full charge. However, some battery packs,
such as those having internal faults or those
recharged more than the number of times
recommended by the manufacturer, will not benefit
from cycling.
1.Insert the battery packs into the slots.
2.Using a paper clip or other fine-tipped tool, press
the Cycling button and hold it down until the
Cycle LED glows. If the LED does not glow, make
sure the battery pack is seated in the bottom of
the slot. If the LED still does not light, see the
“Troubleshooting” section on page 21.
3.Cycling begins automatically. Allow
approximately 20 to 24 hours for cycling, whether
you are cycling one battery pack or up to four.
Cycling is complete when the green LED below
each slot containing a battery pack lights.
4.When all of the green LEDs light, turn off the
cycling function by pressing the Cycling button
(with a paper clip) and holding it down until the
Cycle LED goes off or by removing all of the
battery packs.
