Test Method：
The specified electro-optical characteristics is satisfied under the following
Conditions at the controllable distance.
Measurement place
A place that is nothing of extreme light reflected in the room.
External light
Project the light of ordinary white fluorescent lamps which are not high
Frequency lamps and must be less then 10 Lux at the module surface.
(Ee≦10Lux)
Standard transmitter
