Black spots can occur in case a transmitter is located in the same room as the radiators. In that case, disable the mini IR radiator of the transmitter with the config- uration menu (see section 2.5.16).

Check that the signal delay compensation switches on the radiators are set to the correct value and that a switch is not accidentally positioned between two numbers. Re-check your system design. When neces- sary, reduce the distance between the two radiators that cause the problem and/or add an extra radiator.

Note that due to the physical characteristics of the sig- nal distribution, it is not always possible to completely avoid multi path effects.

Interference from IR systems

IR assistive hearing systems and IR microphones oper- ating at frequencies above 2 MHz, can disturb the reception at the lowest carriers. If such is the case, disable the lowest two carriers (see section 2.5.12) and re-check the reception.
