Wireless Communication

Wireless technology operates 100M / 75M with communication dongle. Maximum communication
range may vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment.

The following conditions may affect the sensitivity of wireless communication.

There is an obstacle such as a person, metal, or wall between this unit and wireless device.

A device using 2.4 GHz frequency, such as a wireless LAN device, cordless telephone, or
microwave oven, is in use near this unit.

Because wireless devices and wireless LAN (IEEE802.11b/g) use the same frequency, microwave
interference may occur and resulting in communication speed deterioration, noise, or invalid connection
if this unit is used near a wireless LAN device. In such a case, perform the following.

Use this unit at least 10 m (about 30 ft) away from the wireless LAN device.

If this unit is used within 10 m (about 30 ft) of a wireless LAN device, turn off the wireless LAN
device.

Install this unit and wireless device as near to each other as possible.

Microwaves emitting from a wireless device may affect the operation of electronic medical devices.
Turn off this unit and other wireless devices in the following locations, as it may cause an accident.

Where inflammable gas is present, in a hospital, train, airplane, or a petrol station

Near automatic doors or a fire alarm

This unit supports security capabilities that comply with the wireless standard to provide a secure
connection when the wireless technology is used, but security may not be enough depending on the
setting. Be careful when communicating using wireless technology.

We do not take any responsibility for the leakage of information during wireless communication.

Connection with all wireless devices cannot be guaranteed.

A device featuring wireless function is required to conform to the wireless standard specified by
wireless SIG, and be authenticated.

Even if the connected device conforms to the above mentioned wireless standard, some devices
may not be connected or work correctly, depending on the features or specifications of the
device.

Depending on the device to be connected, it may require some time to start communication.
Tips to help improve your wireless network
1. Position the access point (host/dongle) in a relatively empty space at central location.
When possible, place the access point in a central location on the high ground (1m or above). If your access
point is against an outside wall, the signal will be weak on the other side of the room.
