24Infrared CommunicationsThe infrared port of this unit can be used to exchange data with another CASSIOPEIA,or with another device equipped with infrared communication capabilities. Rememberthat the two infrared ports must be pointed directly at each other when performingcommunications. 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 communications.For infrared data communications with another device, the other device must conformwith IrDA 1.2 standards, and it must specifically support infrared data communicationwith a CASSIOPEIA.Important• Take care so either of the units does not move while infrared data communicationsare in progress.• Infrared data communications may be impossible under strong sunlight or invertertype fluorescent lighting.• Infrared data communication problems can be caused by the distance between thetwo ports, the angle between the two ports, outdoor sunlight, and low batteries.• Dirt and dust on the infrared port surface can cause communications errors and otherproblems. Use a soft, dry cloth to wipe the port clean of dirt and dust.Using a CompactFlash CardYour CASSIOPEIA supports Type I and Type II CompactFlash cards (3.3V).Important• The card slot cover will not close when certain types of cards are in the slot. Remove thecard slot cover and keep it in a safe place so you can replace it when you remove the card.• 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 you have problems inserting a card, pull itout and check to make sure it is oriented correctly.• We strongly recommend that you store all unsaved data you are inputting or editingbefore performing this procedure.• Sometimes, your CASSIOPEIA may not be able to detect a CompactFlash card. This isindicated when a program on the card does not start up normally. When this happens,remove the card, reinsert it, and then press the CASSIOPEIA RESET button.• Your CASSIOPEIA supports 3.3V CompactFlash cards only. Cards that can operateon 5.0V only are not supported.• Use of an IO card that requires large amounts of power can cause the CASSIOPEIAto restart when CASSIOPEIA battery power is low.
