radiating panel's output interface.

3 DELAY COMPENSATION*25

Delay composition adjusting button, “+” is to

delay increase, “-“ is to delay decrease. The

value for adjusting will be displayed on the LCD

above the button.

Delay composition range: 00~99, that is,

from 0（0*25）ns to 2475ns（99*25）

Cable delay coefficient:5.6ns/m，please refer

to the cable’s specifications for details.

3.4 How to allocation the system

3.4.1 The installation of the radiating panel

The IR can reach the receiver by direct

reflection or diffused reflection. In a conference

hall, the delegates who sit behind others will not

receiver IR signal if it has been screened by the

front row of seats, which has to be taken into

consideration when allocating the radiating panel.

Thus, when the radiating panel should be

installed as high as possible, and generally the

height should be more than 2.5m and the

radiating panels should face the whole

conference hall from various directions to make

sure their radiating area can cover the whole

place.

If the radiating panels are installed highly

enough, the signal intensity of the received IR

signal will not decreased to zero in the shadow
