NOTICE

The unit is equipped with a NiMH
battery pack. It is possible that the
customer might receive the battery pack
in a discharged (dead) state due to
product storage. This is normal.

In the above situation, plug the
9V/500mA AC-DC adapter into the PT500
and an available 110V electrical outlet,
switch on the PT500, and fully charge the
NiMH battery pack for 14-16 hours. Or
place the PT500 into the optional charging
cradle for 3 hours before using the unit.

During the initial charging, switching
on the PT500 is highly recommended. In
addition to charging the main NiMH
battery pack, this will also simultaneously
charge up the backup lithium battery.

Chapter 2 Installation

2.1 Power On and Off the PT-500

Press the Power Key ? located near the bottom left corner
to turn the terminal on and off. As a safeguard, the unit can
only be turned off by pressing the power key ? for at least 3
seconds.

2.2 Batteries

Main Battery

The PT -500 operates with either a rechargeable nickel
metal-hydride (NiMH) battery pack or three standard AA size
alkaline batteries. When the main battery is running low , the
LCD display will start blinking. If the unit is switched off and
on again, a warning message stating “MAIN BATTERY
LOW” will appear on the LCD display.

NiMH Battery Pack

Battery Installation Procedure:

1. Turn off the terminal and place it face down.

2. Move the battery compartment latch to the left to
open. Remove the battery cover.

3. Insert the main batteries:

? NiMH battery:

Place the battery with label facing up; firmly
push the whole pack inside the compartment.

? Alkaline batteries:

5

Insert the batteries in the positions as shown
by the polarity symbols inside compartment

4. Replace the battery cover and move the latch back to
the locked (centered) position.

5. If you are using NiMH battery pack, please charge
the NiMH batteries continuously for 14 to 16 hours
with AC-DC power adapter, or 3 hours with the
optional charging and communication cradle.

Note: The AC-DC power adapter is only for NiMH battery

pack recharging. It won’t recharge alkaline batteries.
Do not incinerate, crush, or puncture batteries.
Do not dispose of alkaline batteries in fire.
Do not attempt to recharge alkaline batteries.

Backup Battery

The PT -500 also has a built-in rechargeable Lithium backup
battery that temporarily protects data stored in RAM. The
power of the Lithium battery is only consumed when the
main power source is not available, such as when the main
battery is removed or discharged. When a functional NiMH
battery pack or 3 AA-size batteries are in the main battery
compartment, power is provided to backup the RAM
memory and system clock, which effectively puts the Lithium
battery in a standby state.

The power circuitry of the PT -500 monitors the voltage level
from the main power source and automatically connects the
Lithium battery for backup once it has detected that
inadequate power is being provided by the main power
source. Under these conditions, the life of the Lithium
battery would be up to 10 hours. Therefore it is highly
recommended that the main battery always be kept
adequately charged inside the unit.

6

When the PT -500 is switched on and the Lithium battery is

BACKUP BATTERY LOW!

discharged, the following low backup battery warning
message will be displayed on the PT -500 LCD:

In this situation you should upload your data from the PT ­500 to a PC and have the Lithium battery replaced. Contact
your local sales or service representative for replacement of
the Lithium battery.

Note: Data may not be backed up and data loss may occur

if both the main battery and the Lithium battery are
discharged.

2.3 Using the Keypad

The Keypad of the PT -500 consists of 36 rubber keys and
one large scanner trigger button. The keypad layout is
shown in the following picture.

2.4 Triggering the Scanner Module

The PT -500 can be used with a built-in integrated
laser or CCD scanner module. To use the scanner, just
point the scanner window at a barcode and press the trigger
that activates the scanner. A short beep from the buzzer
and flashing red LED indicator on top of the LCD display
indicates when the scanning is successful.

2.5 Interface Port

The PT -500 includes a DSUB-9 pin male connector, located
at the base of the terminal, for serial communication with a
PC. Infra red LEDs and charging contacts for the optional
cradle are located on the bottom right below the DB 9
connector. The pin out assignment is shown as follows:

Pin Signal Direction Description
