This enables you to place your A/V components out of sight (behind cabinet doors, in the rear of a room, or in a different room) and still conveniently control your equipment. It is one of three elements that make up an infrared extender system: 1. IR Sensors receive IR commands from hand-held remote controls and relay the commands to the Main System Unit via a 2-conductor shielded cable. [. . . ] · Power LED On: Go to Step 12 · Power LED Off: Go to Step 9 · 12 System suddenly seems to be OK again. The connections were poor and by touching and inspecting them you have changed their condition. If they all seem secure, retest the entire system per the guidelines on page 11. 13 · 9 · Test the Cable for Shorts Disconnect the cable at both ends (at the sensor and at the IRP2+) and test it for shorts. You should read an open (Infinite Ohms) between Red and Bare, Red and Black or Bare and Black. · Short in Cable: Replace cable · Cable tests OK: Go to Step 10 IR LED without any IR input. Observe the green IR Test LED on the IRP2+ with the power supply plugged in and all sensors and flashers connected. · IR Test LED is On or is Flickering: Go to Step 32 · IR Test LED is Off: Go to Step 14 · 14 · 10 11 Replace the IRP2+ If you have another IRP2+, replace the one in the system and retest, if not go to Step 11. IR LED with IR input. Have someone watch the green IR LED on the IRP2+ while you aim a remote control at a remote sensor and press a button. · IR Test LED Flashes: Go to Step 15 · IR Test LED Off: Go to Step 23 · 15 Replace the Sensor or Keypad If you have another Sensor or Keypad, exchange it and retest the system, otherwise return the IRP2+ and the sensor/keypad(s) to your local Niles dealer for testing. · 15 Flasher Connections Verify the polarity of the flasher connections. Examine the con- I NFRARED E XTENDER -M AIN S YSTEM U NIT nectors for a hair-like filament of wire between any of the contacts. · Poor Operation: Go to Step 16 · Poor Operation: Go to Step 19 B) If you have MORE THAN ONE FLASHER, disconnect all of them and reconnect one flasher at a time. · All flashers appear defective: Go to Step 18 · One flasher doesn't work: Return the defective flasher to your dealer · All flashers now work: Congratulations! · 16 Flasher Output Too High Some audio/video component's sensors are overloaded by too strong a command from the flasher. Connect the flasher(s) to the variable output of the IRP2+ and use a 1/8" slotted screwdriver to reduce the output level to minimum (counter-clockwise). · Poor Operation: Move the flasher so that it is farther away from the sensor window or off to the side of the sensor window. · Poor Operation: Start raising the level (a quarter turn clockwise each time) and retesting until level is back to full. · Poor Operation Continues: Go to Step 17 · 18 Test Flasher Outputs Reconnect one flasher to the second flasher output of the IRP2+. · Poor Operation Continues: Go to Step 19 · 17 · 19 Test Flashers. A) If you have only ONE FLASHER, reconnect it to the other flasher output. · Good Operation: Congratulations! Sensors in the Same Room as a Flasher?· If you have sensors in the same room as a flasher: Go to Step 20 · If all sensors are in remote locations without flashers : Go to Step 21 · If you have keypads only: Go to Step 21 16 I NFRARED E XTENDER -M AIN S YSTEM U NIT · 20 Optical Feedback Loop If there is an IR sensor and an IR flasher located within the same room an "optical IR feedback loop" can occur. Replace the IRC-1 Flooding Flasher with an IRC-2 MicroFlasher on the front panel sensor window of each component. · Poor Operation: Go to Step 16 (adjust Flasher Level and Position) Retest system. · 23 Disconnect All Sensors and Keypads and Test One Sensor Input Disconnect all Sensors and Keypads. Reconnect one of the sensor cables and retest the system (Have someone watch the green IR LED on the IRP2+ while you aim a remote control at a remote sensor and press a button). [. . . ] Changes the function of the Source Control Keys so that they operate the selected source. Display which source is selected by backlighting the corresponding Source Label. Turn on the local speakers (un-mute the speaker relay) Status LED When the preamp/receiver is on, the status LED is lit. The color of the LED displays whether the local speakers are on or muted.
