Tips to Help Ensure Successful Communication
Note the following information, which can help you ensure successful Bluetooth® data communication.
•Make sure the Rugged PDA is visible from and within about 3 meters of the other Bluetooth® devices. The communication range may be shorter depend-
ing on the local environment (if there are walls and furniture in the path, or
radio wave is emitted by other Bluetooth® device, etc.), and the structure of 2 the building where you are located.
Ferroconcrete structures in particular can cause problems, because iron reinforcements between floors and in walls can make communication impossible. Perform data communication at least two meters from other devices (electric appliances, AV equipment, office equipment, digital cordless telephones, facsimiles, etc.) Microwave ovens in particular can cause problems, so the distance should be increased to at least three meters. Turning on the power of another device that is too close can interfere with proper communication, TV and radio interference, and reception interference (in particular, distortion of certain UHF or broadcast satellite channel TV images). If proper communication is not possible in the vicinity of a transmitter, wireless device, or other device, move to another location. Very strong radio waves in the area can make proper communication impossible.
Wireless LAN Radio Interference
Since Bluetooth® devices and wireless LANs (IEEEE802.11b/g) use the same frequency band, using the Rugged PDA in the vicinity of a wireless LAN enabled device can generate radio interference, which can result in slower communication speeds and even make connection impossible. If this happens, take the following steps.
•Move the Rugged PDA so it is at least 10 meters from the wireless LAN enabled device.
•If you must use one of the two devices within 10 meters of the other, turn off either the Rugged PDA or the wireless LAN.
The Bluetooth Version 1.2 built into the Rugged PDA allows simulta- neous use of wireless LAN and Bluetooth communication. However, communication may not be possible due to the surrounding electro- magnetic fields.
