Infrared Communication
The infrared port of this unit can be used to exchange data with another unit, or with another device equipped
with infrared communication capabilities. Remember that the two infrared ports must be pointed directly at
each other when performing communication. The distance between the two infrared ports must be less than
20 cm.
See the
Pocket PC User’s Guide
for full details on performing infrared communication.
For infrared data communication with another device, the other device must conform with IrDA 1.2 standards,
and it must specifically support infrared data communication with a unit.
• Take care so either of the units does not move while infrared data communication are in progress.
• Infrared data communication may be impossible under strong sunlight or inverter type fluorescent
lighting.
• Infrared data communication problems can be caused by the distance between the two ports, the
angle between the two ports, outdoor sunlight, and low batteries.
• Dirt and dust on the infrared port surface can cause communication errors and other problems.
Using a CompactFlash Card
The unit supports Type I and Type II CompactFlash Cards (3.3 V).
The following describes the types of CompactFlash which card can be used.
Storage Card
A storage card functions the same as the unit’s data storage memory.
Modem Card
A modem card can be connected to a telephone line (standard household modular jack, public telephone with
modular jack, etc.) for modem data communications.
Wireless Modem Card
With a wireless modem card, it can be performed mobile data communication without a wire connection to a
telephone circuit.
• Gently but firmly slide the card into place as far as it will go, but do not force it. Forcing a card can damage
connectors. If there are problems inserting a card, pull it out and check to make sure it is oriented correctly.
• Sometimes, the unit may not be able to detect a CompactFlash card. This is indicated when a program on
the card does not start up normally. When this happens, remove the card, reinsert it, and then press the unit
reset button.
• The unit supports 3.3 V CompactFlash cards only. 5.0 V cards are not supported.
Using a SD Memory Card or Multimedia Card
The unit supports SD memory cards and Multimedia cards.
• The card slot cover will not close when certain types of cards are in the slot.
• Gently but firmly slide the card into place as far as it will go, but do not force it.
Forcing a card can damage connectors. If there are problems inserting a card, pull it out and check
to make sure it is oriented correctly.
Built-in Storage
The unit comes with two types of user memory built-in: RAM and flash memory. Flash memory appears on File
Explorer under My Device → Built-in Storage, and operates just like a storage card. To find out how much
flash memory capacity is still available, tap Start → Settings → Memory → Storage Card.
