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.  
2.  
Turn off the terminal and place it face down.  
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  
Replace the battery cover and move the latch back to  
the locked (centered) position.  
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.  
4.  
5.  
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  
discharged, the following low backup battery warning  
message will be displayed on the PT-500 LCD:  
BACKUP BATTERY LOW!  
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.

3.4 Application Mode  
Advanced users can create custom programs for the PT-500  
by using the C programming language. The optional PT-  
500 C Kit Technical Binder with C compiler includes an  
ANSI standard compatible Library. Applications can be  
programmed into EPROM to replace the original PT-500  
firmware.  
The PT-500 C Kit includes a Compiler, a Linker, and a  
Library. After copying the PT-500 C Kit onto hard disk, you  
will find:  
\PT500  
A8051 EXE  
C-51 EXE  
XLINK EXE  
XLIB EXE  
HEX2BIN EXE  
Assembly  
C-Compiler  
Linker  
Library Manager

The following steps illustrate how to create an application  
under the MS-DOS operating system:  
1. Select PT500 as the current directory.  
2. Type SETENV to set the environment.  
3. Create a project file called APP.PRJ in the PT500  
directory. It will contain one text line:  
R03\APP.R03 R03\APPRES.R03. We will have  
one C source file in <APP> sub-directory called  
APP.C, and one Assembly source file in <S03>  
sub-directory called APPRES.S03.  
4. TYPE C51 APP.  
5. TYPE ASM APPRES.  
6. TYPE LNK APP.  
7. Get APP.BIN. Download it to the portable and  
run. Hold the scan key down. The portable will  
scan again and again automatically every 3  
seconds.
