2.2 Operation overview

)

(App

)

This section gives an overview of how the sy st em functions at power-on in a sequential order according t o Fig. 2-2-1. The Handheld PC is operated when the CPU executes a program stored in memory. W hen the power switch is turned on, the system checks the battery voltage (except at bootup after reset). If it does not fill a specified battery voltage level the sy stem w ill not start -up. Then it performs a simple test on the DRAM memory . If an error occurs, the program cannot run so that the system will not boot up. If no error occurs, the system will switch to the setting mode for touch panel setting at bootup, after resetting. If the setting is complete, the system will immediately display t he applicat ion scr een. If you would like to check the Handheld PC precisely, see Chapter 7 "T/M Manual".

In the text below, an asterisk (*) on the left side of an item number highlights a precaution for those in charge of maintenance. These precautions are not described in the user’s guide for the main unit.

3.2 Reset Procedure and Precautions

1. Manual reset When the unit fails to operate during operation or a reset instruction is issued during software

installation, press the Reset button with the stylus pen to restart it.

Note: Data being edited that has not been saved in the memory will be lost. Save data at short intervals.

2. Full reset

Cautions on using lithium ion battery (model HPW-LBT2) and coin battery (model CR2032)

Before using such batteries, always read the Hardware User’s Guide. Mishandling may result in excessive heat , ignition, damage, or deterioration of the battery during performance or service life. Observe the following requirements at all times:

Warnings

1. Always read the Hardware User’s Guide for the Handheld Computer carefully, and recharge the batteries. Mishandling may result in excessive heating, a burst, or ignition.

2. Do not throw a battery into a fire or heat it. Mishandling may result in excessive heating, a burst, or ignition.

3. Do not connect the terminals of a lithium ion battery or coin battery with a metal wire or other metal object. Do not carry any such battery into the room with a hairpin or ot her metal product , or st ore t hem together. Mishandling may result in a short-circuit, leading to an excessive current flow, overheating, a burst, or ignition.

4. Do not disassemble or remodel a lithium ion battery or coin battery, or apply a strong impact either. Mishandling may result in excessive heating, a burst, or ignition.

5. Do not sting a lithium ion battery or coin battery with needle;do not hammer them or step them on either. Any such action may result in excessive heating,a burst,or ignition.

Do not dip a lithium ion battery or coin battery into w at er, sea water or other liquid; do not get them wet. Mishandling may result in excessive heating, a burst, or ignition.

7. Do not put a lithium ion battery or coin battery into a microwave oven or high-pressure v essel. Mishandling may result in excessive heating, a burst, or ignition.

8. Do not use or leave a lithium ion battery in direct sunlight, in a vehicle in the strong sunlight, or in an area where the battery can get overheated. Any such attempt may result in excessive heating, ignition, or reduction of service life.

9. The lithium ion battery incorporates a protector designed to protect against risks. Do not use it in an area subject to static electricity that may damage the prot ect or. Any such attempt may destroy the protect o r, result ing in t he excessive heating, a burst, or ignition.

10. If a strange odor, excessive heat, discoloration, deformation, or any other abnormal sign is noticed when using, recharging, or storing a lithium ion battery, or when using or storing a coin battery, remove the battery from the Handheld Computer. Do not use the battery anymore. Continued use may result in excessive heating, a burst, or ignition.

11. If recharging does not end even after a specified recharging time, stop the recharging. Mishandling may result in excessive heating, a burst, or ignition.

12. If liquid leaking from a lithium ion battery or coin battery enters the eye, do not rub it. Imm ediately rinse well with clean water and seek a physician's treatment at once.
