User manual NILES MS-1

[. . . ] 100% factory tested for pickup range and angle. visually confirms remote control operation. Simple 3-wire hookup--10 feet of IR cable included. Printed circuit board design uses surface mount technology (SMT), assuring high reliability. [. . . ] If you are installing the MS-1 near a television, keep it at least 6" away from the top, bottom or sides of the TV to avoid interference. Avoid running the MS-1's cable on the top of the TV, or near the back cabinet of the TV. This will help reduce the possibility of interference. "TECH TIP" DO NOT INSTALL THE MS-1 INTO ELECTRICAL BOXES WITH 110 VOLT DEVICES. Some states or municipalities allow devices such as the MS-1 to be installed into the same electrical box as 110 volt devices, provided a "low-voltage partition" is used between the devices. The cable connected to the MS-1 can act as an "antenna" for electrical noise. Locating the MS-1 cable too close to a light dimmer or switch may interfere with the MS-1. If you must locate the MS-1 near electrical devices, install it in a separate metal electrical box, ground the box to the electrical system ground, and route the MS-1 cable several feet away from all electrical wiring. Do not install the MS-1 next to a light dimmer, or where it will be exposed to direct sunlight. 5 M I N I AT U R E I NFRARED S ENSOR Avoiding Optical Feedback If installing the MS-1 in the same room as an IR flasher, it is possible for the flasher's IR output to be picked-up by the MS-1. This effect, known as an optical feedback loop, can cause erratic operation. Optical feedback is similar to acoustical feedback: the howling or whistling sound heard in a P. A. system when the microphone is too close to the speaker. Lower the output power of the flasher(s) using the variable flasher level control(s) on the Niles Main System Units. Re-position the flasher(s) and/or the sensor. Use Niles IRC-2 flashers and cover them with the supplied IR blockers. Changing the Color of the MS-1 The bezel surrounding the lens on the MS-1 is removable, allowing fast and easy color changes as needed. A black and white bezel are included with your MS-1. If you desire, you may paint the MS-1 bezel yourself -- to blend it seamlessly into your decor. If you need to change the color of the MS-1: 1. Hold the MS-1 as shown in (Figure 1) on next page. Unscrew the bezel by turning it counter-clockwise. Note that the MS-1's lens is held in place by the bezel -- be careful not to lose it. 6 M I N I AT U R E I NFRARED S ENSOR Figure 1 Removing the Bezel 2. Hold the MS-1 so that the front of it is facing you, making sure that the lens is in place. Screw the new bezel onto the MS-1 by turning it clockwise. 7 M I N I AT U R E I NFRARED S ENSOR a b c d e f (a) Hex Nut (supplied) (b) Washer (supplied) (c) Mounting Surface (d) IR Cable (10 feet supplied) (e) MS-1 Miniature IR Sensor (supplied) (f) MS-1 Lens Bezel (supplied) 8 M I N I AT U R E I NFRARED S ENSOR Installation If you are installing the MS-1 into an existing wall, take time to consider any possible obstructions which may be hidden inside the wall, such as wood and metal studs; electrical, telephone or other types of wiring; plumbing; conduit; old wall safes; etc. [. . . ] The LED should light only when a remote command is being received. If the MS-1 does not work, and the LED does not light at all: 1. Test the remote control(s) by operating the A/V equipment directly. Double check the cable connections on all MS-1's and on the Main System Unit. Look for open, shorted or reversed wires. If the MS-1 does not work, and the LED remains solidly lit: 1. [. . . ]
