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:

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.

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.
