Unable to use infrared transfer between Windows CE- based devices

If you are unable to use infrared to transfer information between Windows CE-based devices, try the following.

·Transfer only one file, or no more than 25 contact cards, at a time.

·Position the infrared ports so that they line up and are less than 20 centimeters (8 inches) but more than 2 inches apart.

·Make sure nothing is between the two infrared ports.

·Adjust the room lighting. Some types of light interfere with infrared communication. Try moving to a different location or turning off some lights.

Troubleshooting viewing problems

If you are having trouble viewing your data, here are some suggestions.

Screen is blank

If the device does not respond when you briefly press the On button:

·Make sure your battery cover is locked.

·Adjust the display contrast. On some devices, the screen can darken or lighten to the point that it appears to be powered off. For information on adjusting contrast, see “Setting brightness, contrast, and volume” on page 31.

·Reset the device.

·Charge the main battery by connecting to AC power.

Screen is dark

Prolonged exposure to direct sunlight may cause your device screen to temporarily darken. This is normal for LCD screens and is not permanent.
