1.4 PRECAUTIONS
The following is the excerpt from a user’s guide. For details, please refer to the user’s guide.
1. Precautions at the time of handling and operating the unit
1-1. On charge, power supply, and a battery
1Use only DT-923LI/923LIB for charge battery pack.
2 Use only AA (LR6)-size alkaline batteries when using dry batteries.
If batteries other than alkaline batteries are used, the unit may not operate normally.
3When you remove the backup battery with the main battery removed or in a low-power state, data
may be lost or may change. Data cannot be recovered once it is lost or corrupted. Be sure to make
back-up copies of all important data.
4
The lithium-ion battery pack discharges naturally during its transportation from the factory to an end-user.
Be sure to charge the battery pack before you use it for the rst time.
5 Repeat charging of the lithium-ion battery pack gradually shortens its ability to recharge. If you nd
that a fully charged battery pack provides only little operation time, it probably means you need a
new battery pack.
1-2. Others
1High-sensitivity communications devices are used for the IrDA communications function. Avoid using
units or equipment such as a cellular phone emits radio waves during communication.
To ensure uninterrupted communication, keep the unit away from the equipment (at least 30
centimeters from a cellular phone).
2. Safe Keeping
2-1. Remove the batteries from the unit for long-term storage.
2-2. Please avoid storage (neglect in the car etc.) in the environment exceeding 70 degrees C .
3. Safety Precautions
3-1. Danger
Please conform to a user’s guide.
3-2. Warning
Please conform to a user’s guide.
4. Maintenance
There are no particular parts or parts on articles that need check and replacement periodically.
5. Installation
Please be sure to install and operate the main unit by keeping precautions strictly.

2. FUNCTION AND BASIC OPERATION
2.1 EXPLANATION FOR THE MAIN BATTERY
Handheld terminal can be operated by either two AA (LR6)-size alkaline batteries or lithium-ion battery pack
(DT-923LIB) as main battery.
2.1.1 BATTERY COVER
Be sure to slide the main battery compartment cover lock to the LOCK position.

Important! Makesure thatthe positive (+) and negative(─) ends of the batteryare facingthe
correct directions.
LOADING THE BACKUP LITHIUM BATTERY
1. Use a screwdriver to rotate the screw that secures the backup
battery holder in place counterclockwise to loosen it.
2. Open the backup battery compartment cover.
3. Carefully wipe the backup battery (lithium battery) with a dry
cloth before inserting it with the plus (+) side up as shown in the
diagram.
4. Push the lithium battery in the direction shown by the arrow to
hook it. Hook
5. Close the backup battery cover and tighten the screws.

REMOVING THE BACKUP LITHIUM BATTERY
1. Open the backup battery cover and use a ballpoint pen or other
sharp object to remove the backup battery (lithium battery).
2. Close the backup battery cover and tighten the screws.
2.5 RESET OPERATION
It is the operation done when the unit doesn’t work normally due to an operational error and other malfunctions.
“Reset” is equivalent to “reboot” for PC.
Reset operation erases the data which have not been saved in the middle of input or editing.
But the data which has already been saved on the memory are basically remains.
Reset will return the system menu settings to default value.
Procedure
(1) Press the reset button (hole with the imprint of RESET) on the back side of Handheld terminal with a
pointed object such as a clip.
(2) Reset operation starts as soon as the reset button is pressed.
System menu screen appears after showing the boot-up screen for a few seconds as far as there is no
malfunction in memory. The application program starts up when the automatic application start is set.
There is no change in data or various settings that had been saved in the memory before the reset.

2.7 POWER SUPPLY CONTROL
ON and OFF of a power supply is controlled both by hardware and software viewpoint.
When the main battery is set up, a part of a main board is always is activated.
Therefore, main power turns on when conditions such as power on button or interrupt are detected.
2.7.1 POWER ON
Power is on in the following circumstances.
1) When the power button is pressed
2) When the initialize key (reset key) is pressed

1) A main battery cover is closed.
* Actually, it means a main battery cover detection switch is on.
2) Conrmation of battery voltage
when lithium-ion battery are used: 2.8V or more
when two AA(LR6)size alkaline batteries are used: 2.1V or more
* When the voltage is low, the power turns on instantly and turns off immediately or it happens that
the power does not turn on at all.
Please conrm using fully charged lithium-ion battery pack or brand new AA (LR6)-size alkaline batteries.
3) There is no hardware defect such as over current.
* When over current ows caused by such as hardware defect, the power does not turn on
because the over current protection circuit turns the power off.
2.7.2 POWER OFF
Power is off under the following operation (circumstances).
1) When the power button is pressed
2) When a main battery cover is removed
* Actually, it means a main battery cover detection switch is off.
3) Conrmation of battery voltage
when lithium-ion battery are used: less than 2.8V
when two AA(LR6)size alkaline batteries are used: less than 2.1V
4) When the over current protection circuit detects the malfunction such as over current
