User manual NILES AB-8

[. . . ] For this type of application, place the AB-8 with its L. E. D. 's pointed straight up and at least an inch in front of the equipment you wish to control (See Figure 1). The effective range varies between 8" and 30" depending on the brand and/or the model of the audio/video component. Note: If cabinet dimensions permit, experimenting with the placement of the AB-8 may yield better operating results. For tall stacks of components use multiple AB-8 flashers. [. . . ] For tall stacks of components use multiple AB-8 flashers. For example, place one AB-8 at the top of a stack with the L. E. D. 's pointing down and one AB-8 at the base of the stack with the L. E. D. 's pointing up (See Figure 2). In some installations there are shelves blocking a direct path between the AB-8 and the components' IR sensor window. It is possible to bounce infrared light off of smooth reflective surfaces (particularly white surfaces). If a suitable surface exists (like the back of a cabinet door, or a white wall within a few feet) try to place the AB-8 so that its reflected output reaches the sensor windows of the audio/video components (See Figure 3). If some of the components are still not getting adequate signal, mount a Niles IRC-2 MicroFlasherTMon the sensor window of each of the problematic components. Sometimes, it is desirable to mount the AB-8 so that it directly faces the equipment from across a room. In this type of situation the AB-8 has an effective operational range of 18 to 30 feet (depending on brand and model). Niles offers several wall mount flashers which may improve the cosmetics of this type of installation. See your local Niles dealer for more information. INSTALLATION & OPERATION Route the connecting two-conductor wire to the Main System Unit. IR Transmitting Angle Variable with the brand and/or model of the audio/video component. Because of the high power and "flooding" pattern of the AB-8, extreme transmitting angles can be successfully used if the sensor window of the component is close. Unit Dimensions 1" Wide x 2" High x 3/4" Deep (Includes Velcro) Mounting Supplied with self-adhesive tape attached to Velcro strips Wiring Requirements Supplied with 10 feet of 2-conductor 22 gauge connecting wire. Substitute an 18 gauge 2-conductor wire for distances ranging from 10 to 20 feet and a 16 gauge 2-conductor wire for up to 200 feet. Testing the Remote Control Test that the hand-held remote control operates the component when you point it at the front panel (check the batteries if it does not). Main System Unit Power Supply Check that the red power light on the Main System Unit is lit (the wall adapter should be plugged into an active AC wall outlet and the wall adapter has to be supplying 12V DC). Adjusting the Flasher Level Try adjusting the flasher level up or down (some components sensors are overloaded by too strong a command from the AB-8). If the operation of the component improves when the flasher level is all the way down, but it is still not perfect, try moving the AB-8 so that Optical IR Feedback Loop If there is an IR sensor and an IR flasher located within the same room--an "optical IR feedback loop" can occur. This occurs when the IR output from a flasher unintentionally reaches an IR sensor located within the same room. The IR commands are eventually forwarded back to the IR flasher and the whole process endlessly repeats itself. This effect is similar to acoustical feedback (the howling or whistling sound heard in a P. A. [. . . ] This occurs when the IR output from a flasher unintentionally reaches an IR sensor located within the same room. The IR commands are eventually forwarded back to the IR flasher and the whole process endlessly repeats itself. This effect is similar to acoustical feedback (the howling or whistling sound heard in a P. A. system when the microphone is placed too close to the speaker). [. . . ]
