)

(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".

Cautions

1. When handling a lithium ion battery, read the Hardware User’s Guide for the Handheld Computer. Install
and use the battery correctly.

2. Detaching the lithium ion battery and coin battery at the same time will delete all data in Handheld
Computer.

3. To replace a lithium ion battery and coin battery at the same time, proceed as follows. Prior to replacing
them, connect an AC adapter to the PC and make a backup copy of the data in Handheld Com puter on a
PC or memory card. Then, replace the 1) lithium ion battery first, then 2) coin battery. After the
replacement, restore the data in the backup copy and return the data to Handheld Computer.

4. To replace the lithium ion battery, it is recommended to make a backup copy of the data in the Handheld
Computer on a PC or memory card in advance, to prevent an inadvertent loss of data. Start replacing the
battery. To make a backup copy of data, read the Hardware User’s Guide.

5. The replacement of a lithium ion battery must be conducted within 10 minutes to prevent consumption of
the coin battery. Leaving the Handheld Computer with its lithium ion battery detached will consume the
coin battery, resulting in a loss of data in the Handheld Computer.

6. Before replacing the lithium ion battery, always check that the coin battery level in the Handheld Computer
is "Good". If it is "Very low", replace the lithium ion battery with the AC adapter connected to it, in order to
prevent loss of data from the Handheld Computer. The residual level of the Back-Up Battery can be
checked by Start, Set, Control Panel, and Power Management.

7.

The lithium ion battery is released from the factory in an uncharged state. Read the Hardware User’s
Guide for the Handheld Computer carefully and recharge the battery correctly before using the Handheld
Computer.

8. W hen using this product, always install a lithium ion battery in it. Using the product without a lithium ion
battery in it will result in a breakdown or loss of data.

9. If the ambient temperature of Handheld Computer exceeds 90deg.F(32deg.C), the red lamp will light and
the Handheld Computer may stop the recharging. If this occurs, detach the AC adapter and leave the
Handheld Computer in a cool area. Connect the AC adapter to Handheld Computer and start recharging.

10. The operating temperature range of the battery is as shown below. O perat ing it out side of the
range may damage the battery. It may also reduce the battery performance or service life.

Fully recharged : 32deg.F to 104deg.F(0deg.C to 40deg.C)
Discharged : 14deg.F to 140deg.F(-10deg.C to 60deg.C)
When in storage : -4deg.F to 122deg.F(-20deg.C to 50deg.C)
: less than 1 month (50% recharged)
After a long period of storage : -4deg.F to 95deg.F(-20deg.C to35deg.C)

: 1 month or more (50% recharged)

3-8

11. If a lithium ion battery or coin battery may not be used for a long time, remove it from the Handheld

Computer and store in a dry area. Leaving it connected to the Handheld Computer or st oring it in a w et
area may result in rust being formed or the battery declining in performance.

12. Avoid storing a fully-recharged main battery at high temperatures. Any such attempt may accelerate battery
deterioration when compared to use in room temperature. If it is absolutely necessary to store the main
battery separately for a long period of time, storing the recharge level at 50% or less is recommended. The
recharge level can be checked by Control Panel and Power Management when the Handheld Computer is
powered by battery.

13. A lithium ion battery or coin battery t hat left unused for a long time may be insufficiently charged. Even if

the battery is left unused for a long period, recharge it until it is fully charged according to t he Hardw are
User’s Guide, at least once every six months. Failure to recharge may result in a decline in bat t e ry
performance or service life.

14. Lithium ion batteries and coin batteries have a limited service life. When you find the batteries near their
end very soon, replace them with new ones.
In throwing away a used battery, follow t he ordinances and regulat ions of the local government.

15. The main battery of the Handheld Computer can be recharged approximately 500 times. Repeated
recharging and discharging will gradually reduce the recharge lev el of the main batt ery . The main bat tery is
at the end of its life when, after about 500 recharges and discharges, the recharge level of the main batt ery
is as low as 60% of its initial level.

Note : The service life of the main battery may change slightly depending on t he operating
conditions and ambient temperature. At low temperatures, the operation time may get
extremely short due to the characteristics of the lithium ion battery.

16. Store the lithium ion battery and coin battery out of reach of small children. When using any such
battery, make sure that small children do not take them out of the Handheld Computer.

17. Read the Hardware User’s Guide or instructions carefully. Store the Hardware User’s Guide or instructions

4.2 Troubleshooting

4.2.1 Troubles at turning on the power
If the LCD displays nothing at turning on the power, check it according to Fig. 4-2-2.

The primarily presumable cause is that the main battery in the Handheld PC is consumed, therefore check it
with the AC adapter.
Another presumable cause is imperfect contact between a harness and a connector. Check the items listed
below as well.

(1) Check that the ROM connector is correctly connected to the connector (CN10) of the sy st em board

(DW0Z725) respectively. If they are not, connect the connect or, make a full reset, then turn on the power
again.

(2) Check that the LCD Flexible Cable is correctly connected to the connector CN900 of the system board

(DW5Z724). If it not, connect the LCD Flexible Cable and turn on the power again. (See page 4-14.)

(3) If the LCD Flexible Cable is correctly connected in step (2), replace the LCD. I f the new LCD does not

display anything, replace t he LCD Flexible Cable. If it still does not display anything, replace the board of
the system.

Before performing maintenance, remove the AC adapter, main battery, Back-Up Battery, and
Cradle.
At that time, all user data will be lost . M ake backup copy of t he us er dat a on a PC or memor y

4.3 Dealing with a system runaway
When a program runs away, the system may get into such a state that it cannot be t urned off the power. In such
a case, press the reset switch in the back of the Handheld PC as shown in Fig. 4-3-1. This causes a forceful
reset (manual reset). If an actual reset still does not occur, remove the Back-Up Battery at fir st, then the Main
Battery, and wait at least one minute. This oper ation causes a full reset. In this case, the system will lose all dat a
in memory and return to its initial state. Next, install the Main Battery at first, then the Back-Up Battery. Press the
reset switch to boot up the system.

Setting up the Main Battery and Back-Up Battery
If the main battery is completely discharged at a sy stem bootup from the full reset as described above, (that is, if
the Main Battery level is as low as 4.8V or below ), t he system may be unable to boot up normally. If the system
is not used for a long period of time, it may go into a full reset state, and the system may not be able t o boot up
normally when the batteries are installed again. Should these event s occur, operat e t he setup as described
below.

(1) Replace the AC adapter, Main Battery, and Back-Up Battery.
(2) Leave the system alone for at least one minute.
(3) Install the Main Battery.
(4) Connect the AC adapter.
