How to Fine-Tune the Installation Using the Dip Switches

At the bottom of the Blaster unit, you find 5 dip switches (numbered 1-5). When you use Dual IR emitters to send the IR signals to the audio/video devices, configure the dip switches to:

■Turn the IR blaster on or off (independently from the Dual IR emitters);

■Configure the power levels of the Dual IR emitters, e.g.:

■When you configure the Dual IR emitters in wired IR solutions using a connecting block.

In this case, you can adjust the power levels of the Dual IR emitters.

■When you use a device that interferes with IR signals, such as a plasma TV set.

In this case, you can raise the power levels of the Dual IR emitters, since plasma technology might cause IR interference.

■When you want to operate 2 identical devices that are placed next to each other using 2 RF Extenders.

In this case, you can lower the power levels of the Dual IR emitters, in order to prevent the devices from receiving IR signals intended for another device.

Switch	Switches 1 + 2	Switches 3 + 4	Switch 5
Function	Dual IR emitters 1 - 2	Dual IR emitters 3 - 4	IR blaster
	Power level	Power level	On/Off

By default, all dip switches are set to 1 (On).

How to Turn Off the IR Blaster

When you decide to control the audio/video devices with Dual IR emitters only, you can turn off the IR blaster of the Blaster unit.

■To turn off the IR blaster, set switch 5 to 0 (Off).

How to Set the Dual IR Emitter Power Levels

You can use dip switches 1 to 4 to set the power level of the Dual IR emitters.

To set the power level:

■For Dual IR emitters 1 and 2, use switches 1 and 2;

■For Dual IR emitters 3 and 4, use switches 3 and 4.

You can choose between 4 power levels (0, 1, 2 and 3). By default, power level 3 is selected for each group of Dual IR emitters.
