1.3 Using the Keyboard
The keypad of PT600 consists of 27 rubber keys, the  key is used to
switch on/off the unit and other 26 keys are used to control the unit and
key in data. The use of keyboard is categorized to three modes: normal
mode, command mode, and alpha(betic) mode. All keys except  key
may produce a sound (tone) when pressed. Keys of upper four rows have
larger size for easier key-pressing to input numbers.
[]When the unit is off, pressing the  key will turn on the unit.
On the other hand, when the unit is on it is needed to press
and hold down the  key for about one second in order to turn
the unit off.
[CMD] Pressing the [CMD] key sets the keyboard to Command
mode. However pressing and holding down the [CMD] key
for two seconds in Ready mode will enter the User mode. In
User mode, users can invoke system commands by menu
selection.
[ESC] In User mode or Supervisor mode, pressing the [CMD] key
and then pressing [ALPHA] key will exit from the current
operation to the previous operation.

NORMAL mode
Keyboard of the PT600 is initialized to normal
mode after powered on. In normal mode, the
cursor is a block sign and the keyboard is mainly
used to input numeric data and use F1-F4 four
function-keys. The keypad layout of available
keys in normal mode is shown on right picture.
 key for next data search
 key for last data search
COMMAND mode
Press [CMD] key sets the keyboard to command
mode. In command mode, the cursor type keeps
same and the keyboard is mainly used to input
special characters, make hot-key function, and
use F5-F8 four function-keys. The keypad
layout of available keys on command mode is
shown on right picture. There are three hot-key
functions and the usage of each function is
described below.

Enter
Clear

-11 -
ALPHA mode
Press [ALPHA] key to toggle between normal
mode and alpha mode of keyboard. In alpha
mode, the cursor is an underscore sign and the
keyboard is available to input upper case
letters. In alpha mode, every numeric key
contains 3 characters individually. Pressing the
key [è]and [ç] to choose among three
available characters.
For example :
First press [ALPHA] to switch the system to
alpha mode, the cursor type will be changed
from block to underscore
To enter ‘A’, hit [ç] then [7].
To enter ‘B’, hit [7].
To enter ‘C’, hit [è] then [7].
1.4 Triggering Scanner Module
The PT600 can be used with a built-in integrated laser scanner module or
clip-on pen scanner module. The built-in decoder reads barcode labels of
all major bar code labels.
The user should keep laser window or tip of pen clean to prevent low
reading rate of distorted bar code input signal.

1.5 Application Development Environment
The system of PT600 provides DOS functions and device drivers for
application development, including bar code decoding, keypad input,
display output, serial input/output communication, real-time-clock access
and power management control.
The PT600 can be programmed by the high-level Windows-based JobGen
Plus and DOS-based JobGen Pro program generation software. It can
also be programmed by commonly used C compilers including Microsoft
C, Borland C and Turbo C. An executable program generated by JobGen
Pro, JobGen Plus or created by a compiler is downloaded to the unit and
run on the unit.
JobGen Plus
JobGen Plus is a Windows-based program generator that gives the user an
ease-of-use and comprehensive terminal application developing
environment. Through the use of JobGen Plus, user can design an
application program for a data collection terminal by simply drawing the
data collection sequence on paper, and thus, requires minimum
programming skills.
JobGen Pro
The Job Generator Pro is a DOS-based program generator software of the
PDT. With the Job Generator Pro, users can easily create the applications
by defining the data fields of a transaction and then download an
executable program generated by JobGen Pro to the PT600. After data
collected and processed on the PT600, the data can be uploaded to the PC
for further processing.
For more detailed information, please refer to PT600 Programming
Reference Manual, JobGen Plus User's Manual and JobGen Pro User's
Manual respectively.

1.6 Optional Charging/Communication Cradle
An optional charging/communication cradle (docking station), PT016,
gives users a convenient accessory for daily use of the PT600. The cradle
has been incorporated a quick charge circuit that the NiMH battery pack
installed in the unit along with an extra spare pack can be fully charged in
about 2.5 hours. Regular charging time of the battery pack through DC
power adapter is about 14~16 hours. The cradle also allows users to link
the PT600 to host computer through point-to-point RS-232 or multi-point
RS-422 connection for data communication. The cradle with internal
modem will be available in the future.

Chapter 2 Power System
2.1 Power Supply
Main Power
The PDT is operated by a rechargeable NiMH battery pack with two AA
size 1.2V 1500mAH capacity or two AA alkaline batteries for the main
power source.
Back up Power
An onboard 3V 190mAH Lithium battery (CR2032) is used as the
secondary power source to back up the data in RTC (real time clock chip)
and RAM memory to provide users a data-loss free environment.
Normally the PT600 gets power from main power source to back-up RTC
and RAM and puts the Lithium battery in standby state. When the main
power source is removed or below the level to back-up the RAM and
RTC properly, the power circuit of the PT600 automatically switches to
the Lithium battery for back up. It is recommended that the main battery
be always placed inside the unit with enough capacity for back-up
purpose in which case the Lithium battery can supply the power for up to
5 years before consuming all its capacity up.
2.2 Power Low Indication
Main Battery
When the main power source reaches the
battery low condition, a warning message as
right will be shown on the LCD when PT600 is
powered on or a battery low icon signwill
emerge on the right sidebar of LCD.
! WARNING !
MAIN BATTERY
VOLTAGE LOW

-15 -
When the main battery low condition occurs, the main battery can
continue to supply power for about 10 ~ 30 minutes, however the unit
may reach the system power cutoff point and automatically turn itself off.
Meanwhile the unit continues to back-up the data contents in RTC and
RAM, but it cannot be powered up until the batteries have been recharged
or replaced.
Lithium Backup Battery
When the Lithium backup battery doesn't have
enough capacity to back up the system, the
message as right will be shown on LCD when
the unit is powered on. In this situation you
should upload your data from the PDT immediately and replace a new
Lithium battery.
2.3 Battery Replacement
Main Battery
1. Make sure the unit is turned off.
2. Turn over the unit. Slide tab from right to left (see illustrations in next
page).
3. Slide the main battery pack from battery compartment.
4. Insert the new main battery packet:
