Chapter 2 Before Use
This chapter explains the prohibitions and precautions when using the device.
To always use the device in its proper state, follow all the instructions below without
fail. Failure to do so may cause malfunction or damage. SII Data Service Corp. takes
no responsibility for damage caused by use of the device that does not comply with
proper usage outlined in this manual.
2.1 Precautions for use
(1) Never alter or modify the device. The device has a built-in wireless facility that has
received technical standard compliance certification according to the Radio Law.
Using illegally modified devices may be punishable under the Radio Law.
(2)Take care not to drop, bend, or strongly shock the device, as the device has a
highly-sensitive wireless facility built-in. Contact your local service center if the
device is damaged in an accident or is dropped during use. Never get the device
repaired anywhere other than the service center.
(3)Do not place objects or rest your hand on the device.
(4)Do not place food or drinks, such as coffee, or hot objects such as cigarettes, on
the device.
(5)Do not wash or pour liquids, such as water or oil, over the device. It is not
waterproof.

2-2
(6)Never store or leave the device in any of the following locations. This may result in
case deformation or device malfunction, such as reduced or deteriorated battery
performance, or memory loss.
・ Locations with temperatures below 5°C
・ In vehicles during summer
・ Locations near air-conditioning equipment
・ Locations with direct sunlight
・ Locations with temperatures higher than 40°C
(7)Avoid using the device in the following locations:
・ Locations with magnetic fields (i.e., near microwave ovens, electromagnetic
cookers, industrial refrigerators, ice makers, devices with built-in motors.)
・ Locations surrounded by conductive materials, such as metals
・ Locations near high-temperature devices, such as microwave ovens and
electrotherms
・ Locations potentially exposed to moisture or water vapor
・ Locations with severe environmental changes in temperature and humidity
・ Locations where corrosive gasses or saline may be generated
・ Dusty or dirty locations
・ Locations where vibration occurs
・ Locations with direct sunlight
(8) Do not press the sheet keys, side keys, or touchscreen with sharp or hard objects,
such as a ballpoint pen. This may result in malfunction. Operate the device with
your fingers, and do not press forcefully with fingernails.
(9)Do not apply excessive force to open a fully open cover. The sheet key unit is
configured with a hinge for double truck. Force may damage the sheet key unit
hinges, resulting in reduced service life.
(10) Do not press the touchscreen forcefully or apply shock. This may result in
cracking, as the screen is made of glass.
(11) Precautions for battery pack use
1. The battery pack is not charged before shipping. Charge it before using. The
battery will be charged in about 4 hours, but it could take longer if using two
chargers in tandem.
Follow all precautions described in each chapter.
2. If the LED starts flashing orange, replace with a charged battery pack
immediately.
Continued battery use without replacement may cause loss of internal data.
The fully charged backup battery saves the data for about 10 minutes.
3. Do not remove the battery pack even when the device is not in use. If the
device is left without the battery pack mounted, the internally stored
programs and data will be deleted. This may also reduce the backup battery
life. After mounting the battery pack, the backup battery will require 1 to 2
days to charge.
Note: Do not “use the battery pack during the day, and remove at night to
charge”. Ensure you leave the battery pack mounted to the device
throughout the night.

Chapter 2: Before Use

(12)Dispose of the device according to the regulations of your local government. For
details, consult your local government.
Follow all precautions described in each chapter.
2.2 Charging a Battery Pack
Charge the battery pack with the SA-5320 Charger before use. See “SA-5320
Charger Instruction Manual” for how to charge.
Caution
Charge the battery pack before using it for the first time.
2.3 Carrying the Device
When using the device, use the strap to prevent the device from being dropped. Do
not carry the device in a way that unreasonable force is constantly applied. This may
cause malfunction or deformation.

2.4 Storing the Device
(1) Short-term storage
If not using the device for a short period of time or less than 1 week, store it with a
fully-charged battery pack mounted. Without a battery pack, the application programs
could be deleted.
(2) Long-term storage
If not using the device for one week or longer, remove the battery pack before storage.
Before resuming use of the device, mount a fully-charged battery pack, reset (see
“3.4: Reset”), and transfer the application programs from the Wireless Station.
