Optical or Electromagnetic

Interference:

Direct sunlight, neon signs, television sets, light

dimming controls and other sources of

electromagnetic fields can induce noise and

interference into your IR repeater system. Symptoms

can include: flashback LEDs continuously flickering

or on without any remote control use, poor range,

intermittent operation or no operation.

Solution:

1. Move the receiver or the receiver cable away from

the EMI source or move the source of the EMI

away from the Receiver or the cable.

2. Connect the receiver's GND terminal to true earth

ground (if this isn't feasible use the main system

unit's GND terminal).

Optical Feedback Loop:

If you have an IR Receiver in the same room as a

emitter, and you have some low-level noise or

interference, an optical feedback loop can occur

which will interfere with proper operation. Symptoms

can include: poor range, intermittent operation or no

operation.

Solution:

Replace any IR-E1HO "flooding Emitter" with IR-E1 or

IR-E2 Emitters and cover all emitters with the

supplied IR Blocking Covers.
