2.4 Installing, Replacing and Charging Batteries
Wrong use of batteries might cause serious damage to the terminal or to the cradle. In order to
avoid damage, it is very important to take notice of the instructions.
Caution:
Required batteries:
The terminal needs both main battery and backup battery for operation.
Main Battery
Terminal: Rechargeable 3.7V 2000mAh Li-Polymer Battery
Gun type: Rechargeable 3.7V 4400mAh Li-lon Battery
Backup Battery
♦ Insert a fully-charged battery pack before use of the terminal.
♦ Never remove the main batteries while the terminal is turned on.
Doing so may lose data in the terminal.
♦ Use only recommended batteries.
When other batteries are used, defects or other problems can occur. Before
installing (new) batteries, please make sure you are using the recommended
batteries.
♦ Use the right charger for batteries.
The rechargeable battery pack form Argox can be charged in the cradle when
either it is in the terminal or alone in the charging slot in the back of the cradle.
♦ The life of a battery pack is limited, and charging a battery pack
causes it to gradually lose its ability to maintain a charge. If your
battery pack requires frequent charging, it probably means it is time
to purchase a new one.
♦ A fully charged backup battery can maintain memory (RAM)
contents for about 15 minutes, even when the battery pack is
removed.
♦ Strictly follow the instructions for installing, charging, and removing
the batteries.
The products are not warranted for damage, defects, malfunction, or loss of
data, resulting from incorrect use of batteries.

Place the PT-20 into the cradle (first connect the power supply to the cradle)
How to charge Argox rechargeable battery pack in the cradle
1. Make sure that the Argox rechargeable battery pack is inserted in the terminal. If the
terminal with the battery pack is placed in the cradle, the LED on the cradle will turn
Orange first and turn to Green at once. When the terminal is placed in the cradle, the
rechargeable battery pack will be charged automatically.
2. If you have a spare Argox battery pack, you can replace the empty battery pack with
a full battery pack for continuous terminal operation. And put the empty battery
pack in the charging slot of the cradle. The LED (CHG) on the cradle will turn to
Red in flashing and turn to Green again when the battery is full.
When to replace or recharge the main battery
There are two conditions that you need to replace the main battery.
1. As soon as possible after the battery indicator or “Battery Low” tip appears on the
display.
2. Before using the terminal again, in case it has not been used for an extended period.
Caution:
Ambient Temperature Ranges for the Battery Pack
♦ Temperature ranges for battery pack use in the terminal, charging,
and storage is specified below. Temperatures outside these ranges
create the danger of deterioration of battery pack performance and
shortening of its service life, as well as fluid leakage and heat
generation.
Operating Temperature: -20 to 50
Charging Temperature 0 to 40
Storage Temperature: -20 to 60
♦ If the battery pack charge indicator does not light during charging,
remove the battery pack and then re-attach it. If this does not solve
the problem, it means that the battery pack is defective and needs to
be replaced.
♦ Use only the specified battery pack.
♦ Battery packs naturally discharge even when they are not loaded in
the terminal. Use a battery pack as soon as possible after charging it.
♦ For best charging results, keep the cradle, terminal and battery pack
contacts clean by periodically wiping them off with a cotton swab or
dry cloth.

2.5 Installing in a System
Notes:
System Connection (Data Communication)
The PT series portable data terminals let you link to a host terminal through the CRD-20
cradle for data communication.
The CRD-20 cradle provides two methods for data transmission: through an RS-232 cable (9pin connector for PC and 9-pin connector for terminal) and through a USB cable.
♦ Exercise caution at all times when working with AC-powered equipment.
♦ Turn off your devices before installation.
♦ Because of the special pin-out of the connectors, use the cables supplied by
the manufacturer.
♦ Do not modify the cable provided by the manufacturer. If you need a special
cable for some cases, contact your supplier to purchase the right cables or
technical support.
Notes:
♦ When both RS-232 and USB cables are connected between the CRD-20
cradle and host terminal, the USB interface takes priority for data
transmission and the RS-232communication is automatically disabled.

3. Operation of the Terminal
3.1 Software Description
The functionality of the terminal is determined by software, e.g. user application that is
running on the terminal.
Usually, the terminal is not equipped with software. There are only some simple functions can
be tested (like scanning test, com port test).
Tools provided by Argox for developing a user application are:
Software Development Kit (SDK); ARM code, C compiler and C library for
handheld terminal
The user application must be downloaded from the PC into the terminal. You can use the
cradle between the terminal and the PC. A program (FileManager) on the PC will send the
user application to the terminal, where it is stored in Flash ROM.
Notes:
When the functionality of the terminal is defined by the application, it is ready for operation.
In a typical application, you will press the trigger key and scan a bar code label as described in
the next paragraph. Scanned data and data entered from the keypad are stored in the terminal’s
RAM. The user application can use this data in subsequent steps.
The collected data can be transmitted to the PC further processing through the cradle.
♦ ”FileManager” will detailed explain in separate manual.

4.3 Applications
Function
User can execute a designed program and proceed to collect and store data based on the
demands in the program. This program needs to be generated by SDK and downloaded with
relative files into terminal by FileManager.
The terminal can store several programs and user can execute one of these programs by
selecting in menu. Or user can use Program Mode to specify a program, and then the
terminal will start running this specified program when power on.
You can set in the program whether the collected data needs to be stored or not. If it
needs to be stored, all the data files will be stored in C:\Data directory. Users can edit
the data file in System Tools\Edit Data.
Every user program is a Project. It includes the following files:
Item
Program ABP D:\Program Main program in Project
Lookup file DAT D:\Lookup
Fonts
Data DAT C:\Data
Note:
Argox will not be liable for any damage or system crash by improper operations of
firmware change without advice or instruction from Argox or Argox’s authorized
support center.

Description
When user collects and confirms
the collected data to terminal,
the system will search the
specified lookup file for any
matched string, and replace it
with the data shown on the
display.
SFT is the system font and CFT
is downloaded font. For detailed
specification, please see in

4.4 Upload /Download by File Manager
The way to upload /download by supervisor menu will need the operator to set the terminal to
supervisor menu by selecting Transfer in supervisor menu or calling system function n
application program.
The hardware and software of terminal is designed that the unit can be turned on by input from
serial port. Besides, the terminal can also be instructed to process data communication by
FileManager through built-in MULTI communication protocol.
After linking the terminal to a PC/ host through RS232 interface a communication program
running on host first sens a few of dummy bytes to the terminal and delay for about 500 minisecond to remotely wake up the unit. Then the program can send out a data pack of a remote
FileManager that matches the MULTI protocol to the terminal and instruct the terminal for
certain process.
For instance, the terminal will automatically execute the system routine to upload a file after
receiving the valid “File upload” FileManager. Meanwhile the program running on the host
should follow the control flow of MULTI protocol and process to receive the data.

5. Scanning
Note:
Fit the bar code in the LED light beam from margin to margin and pass the scanner downward
over the bar code, as shown in the scan position illustration
♦ Observe handling precautions.
♦ Make sure the mobile terminal is installed according to instructions.
♦ Never remove the main batteries or battery pack while the mobile
terminal is turned on. Doing so can cause loss of data in the mobile
terminal.
♦ Avoid looking directly into the LED light beam emitter, or pointing the
LED light beam directly into someone’s eyes.
Good read scan position
Incorrect read scan positions
5.1 How to read the barcode
The scanning sequence is defined by the user’s application. A typical sequence is:
Press the PW key to turn power on.
Get into the System Tools\Scan Test and you will find the message on the display:
<ScanTest>
Type:
Len:
Point the terminal to the barcode and press the Trigger key .
Point the LED lightbeam to barcode as shown in the scan position illustration.
The barcode will be read and the reading results will be indicated.
A “Good Read” means that the scanner has effectively recognized and decoded the bar code.
In most cases, the application program will provide an indicator signal or a buzzer signal to
indicate a good read to the user.
When the read is incorrect you can try again, paying attention to the instructions in this
chapter.
When reading a small bar code, decrease the distance between the terminal and the bar code.
29
Page 35
For larger bar codes, position the terminal so that the bar code fits into the LED light beam.
When reading a very high density bar code, decrease the distance between the terminal and the
bar code. For a low density bar code, increase the distance between the terminal and the bar
code.
5.2 Barcode reading problems
When the barcode can not be read, try the following:
Change the angle between the bar code and the terminal.
Change the distance between the bar code and the terminal.
If the bar code is larger than the LED light beam, try moving the terminal a bit further
away from the bar cod

6. Communications
6.1 Cradle Communication
The CRD-20 cradle provides two methods for data transmission: through an RS-232 cable (9pin connector for PC and 9-pin connector for collector) and through a USB cable.
When both RS-232 and USB cables are connected between the CRD-10 cradle and
host computer, the USB interface takes priority for data transmission and the RS232communication is automatically disabled.
31
Page 37
6.2
Bluetooth Communication
The Bluetooth interface can be used to transfer data to and from a Bluetooth compatible
printer. Data can be transferred if the terminal is located within three meters of the target
device (and nothing is blocking the signal).
Caution:
Observe the following precautions to help ensure that Bluetooth communication is
successful.
♦ Make sure the terminal is visible from and within about 3 meters of the
other Bluetooth devices. The possible communication distance may be
shorter depending on the surrounding environment (such as
obstructions).
♦ Make sure there is at least rwo meters (6’ 7”) between the terminal
and other equipment (electrical appliances, audio-visual equipment,
OA equipment, and digital cordless telephones, facsimile machines,
etc.) (Take special care with microwave ovens. Allow at lease three
meters (9’ 10 3/4”) between the terminal in wireless operation and a
microwave oven.) When approaching such a device when its power
is turned on, proper communication may prove impossible while this
may also cause interference with TV and radio reception (images
produced by certain UHF and broadcast satellite channels may
become blurry)
♦ Normal communication may not be possible in an area near a
broadcast transmitter or wireless transmitter. If this happens, move
to a different location. Normal communication may not be possible
in areas exposed to strong radio waves.
♦ RF Wireless LAN Interference
Because Bluetooth and RF wireless LAN use the same frequency
band (2.4GHz0, radio interference can occur if there is a wireless
LAN device nearby. This can result in lower communication speeds,
or even make it impossible to establish a connection. If this happens,
try the following countermeasures.
Move at least 10 meters (32’ 10 3/4”) away from the wireless LAN
device.
If you cannot keep the distance at least 10 meters (32’ 10 3/4”) or
more between the terminal and wireless LAN device, turn off the
power of either the terminal or the wireless LAN device.
