How to set up

Equipment shall be installed away from devices

generating noise.  Noise may cause trouble in
communication.

Antenna of the equipment shall be set away from a wall

or pillar made by metal and concrete.  They may cause
trouble in communication.

Equipment shall be so installed that a ventilation
openings of a heat radiation are not to be blocked.  It

may cause fire or damage due to over heat.

3.1

 

  Attentions to setting up

The service area of the wireless LAN adapter covers from 10 to 60m

approximately, but it varies depend on presence of obstacles.

Where this equipment is enclosed with an object shutting out the radio wave

such as the metal partition, or source which generates an interference with
the radio wave is exists near this equipment, the communication distance

might be shortened.  To produce a performance of the wireless LAN adapter
fully, please make sure following before setting up this equipment.
