ORDER NO. CPD0606050C1

Wireless Display

CF-08TX1A1M

This is the Service Manual for

the following areas.

M …for U.S.A.

Precautions

Battery Pack

Care should be exercised with regard to the following in order to avoid the possibility of overheating, fire or damage.

Avoid Heat

Do not throw the battery pack into a fire or expose it to excessive heat.

Keep Articles Away

Do not place the battery pack together with articles such as necklaces or hairpins when carrying or storing.

Do Not Disassemble

Do not insert sharp objects into the battery pack, expose it to bumps or shocks, deform, disassemble, or modify it.

Do Not Short

Do not short the positive (+) and negative (-) contacts.

Avoid Extreme Heat, Cold and Direct Sunlight

Do not charge, use or leave the battery pack for extended periods where it will be exposed to direct sunlight, in a hot place (in a car on a sunny day, for example), or in a cold place.

Do Not Use With Any Other Equipment

The battery pack is rechargeable and was intended for the specified equipment. Do not use it with any equipment other than the one for which it was designed.

Do Not Use This Wireless Display with a Battery Pack Other Than the One Specified

Use only the specified Panasonic battery pack (CF-VZSU44U) with your CF-08. Use of batteries other than those manufactured and supplied by Panasonic may represent a safety hazard.

Do Not Put into a Microwave

Do not put the battery pack into a microwave oven or a pressurized chamber.

Stop Using

Should the battery emit an abnormal odor, become hot to the touch, become discolored, change shape, or become in any way different from normal, remove it from the wireless display and stop using it.

Do not touch the terminals on the battery pack. The battery pack may no longer function properly if the contacts are dirty or damaged. Do not expose the battery pack to water, or allow it to become wet. If the battery pack will not be used for a long period of time (a month or more), charge or discharge (use) the battery pack until the remaining battery level becomes 30% to 40% and store it in a cool, dry place. This wireless display prevents overcharging of the battery by recharging only when the remaining power is less than approx. 95% of capacity. The battery pack is not charged when the wireless display is first purchased. Be sure to charge it before using it for the first time. When the AC adaptor is connected to the wireless display, charging begins automatically. Should the battery leak and the fluid get into your eyes, do not rub your eyes. Immediately flush your eyes with clear water and see a doctor for medical treatment as soon as possible.

NOTENOTE

The battery pack may become warm during recharging or normal use. This is completely normal. Recharging will not commence if internal temperature of the battery pack is outside of the allowable temperature range (0 °C to 45 °C {32°F to 122°F}). Once the allowable range requirement is satisfied, charging begins automatically. Note that the recharging time varies based on the usage conditions. (Recharging takes longer than usual when the temperature is 10 °C {50°F} or below.) If the temperature is low, the operating time is shortened. Only use the equipment within the allowable temperature range. The battery pack is a consumable item. If the amount of time the equipment can be run by using a particular battery pack becomes dramatically shorter and repeated recharging does not restore its performance, the battery pack should be replaced with a new one. When transporting a spare battery inside a package, briefcase, etc., it is recommended that it be placed in a plastic bag so that its contacts are protected. Always power off the equipment when it is not in use. Leaving the equipment on when the AC adaptor is not connected will exhaust the remaining battery capacity.

time, then press the Power button to turn on the computer. Self-Test Program starts

automatically.

3. Self-Test

This test is to check if the device is disconnected.

3.1. Test Items

Condut the device test in the following order.

(1) CPU Type check

(2) SDRAM march test

(3) Test register check for the source microcomputer

(4) ID check and frame buffer test for 2700G(GRAPHIC)

(5) Test register and chip ID test for LAN9118

(6) Card detection pin check and tuple information check for PCMCIA

3.1.1. CPU Type check

Check if the CPU is mounted with Intel PXA270 C5 Stepping.

3.1.2. SDRAM march test
