    How Do Remote Controls Work?

    • Generally, there are two types of remote controls: infrared (IR), and radio frequency (RF). Infrared remote controls work by sending pulses of infrared light to a device, while RF remote controls use radio waves in much the same way. Pragmatically, the biggest difference between the two is range. IR remote controls require a clear line of sight to the receiving device and their range maxes out at about 30 feet (9.14 meters). RF remote controls can go through walls and around corners, with a range of roughly 100 feet (30.48 meters)
    • Most home entertainment components such as stereos, televisions and home entertainment centers use IR remote controls. The remote contains an internal circuit board, processor, and one or two Light Emitting Diodes (LEDs)
    • When you push a button on a remote control, it transmits a corresponding code to the receiving device by way of LED infrared pulses. The idea is somewhat akin to flashing an SOS signal, but instead of letters, the flashing LED light is transmitting a series of 1s and 0s. The "1" might be represented by a long flash, while "0," a short flash. A receiver, built into the component, receives the pulses of light and a processor decodes the flashes into the digital bits required to activate the function
    • Along with the desired function, remote controls must also piggyback other data. Firstly, they transmit the code for the device they are controlling. This lets the IR receiver in the component know that the IR signals it is picking up are intended for it. It essentially tells the component to start listening. The function data follows, capped by a stop command to tell the IR device go back into passive mode
    • Some remote controls can be very finicky, requiring the user point the remote directly at the component. This is due to a weak transmitter. Changing the batteries can help, but if the transmitter itself is poor, pulses are transmitted in a narrow beam. More robust IR transmitters, and remote controls with double LEDs, transmit broader beams that allow the user to point the remote in the general direction of the transmitter
    • Sometimes it happens that a recliner or favorite spot on the couch does not have a clear line-of-sight to the entertainment center or television. Often a coffee table or some other object is in the way. When this happens we find ourselves raising an arm, trying to control the object "around" the device. This can get quite annoying, but there's an easy alternative
    • Since light bounces off objects it is sometimes more convenient to point remote controls towards a flanking wall or even the ceiling to change a channel or send a function command. The light will bounce off the surface of the wall or ceiling and scatter. If you bounce it at an advantageous angle, the scattering light will reach the component. Often it's easiest, with elbow resting on an armrest, to flip your wrist back and point the remote up at a wall behind you. This can work quite well, even though the remote is pointing in the exact opposite direction of the component. Once you find the easiest sweet spots around the room from which to bounce your signal, you can use these instead of struggling with trying to get around your obstructed line of sight
    • Garage door openers, alarm systems, key fobs and radio-controlled toys use RF remote controls. RF remote controls work essentially the same as IR remote controls, except they use radio waves. As stated, radio waves can also penetrate walls and go around objects and corners, making RF arguably more convenient than IR
    • Some high-end entertainment systems come with RF remote controls for expanded remote range. There are also IR-to-RF remote control converters that allow IR remote controls to extend their range through utilizing a RF translator that basically acts as a middleman. The RF converter relays the IR signal in RF waves to get it further. The converter on the component side reverts the RF signal back to IR so the component can understand it

Good - so far
00:00:00 05-26-2011
I love it. I got it refurbed, and hope it will continue to work. Charging every 4 days. Wondering if the battery was new. The smart buttons are too small, this is the only negative comment I could make.

Switch Board
00:00:00 05-22-2011
This remote is easy to set up. It works all the components flawlessly. The buttons are labeled so it is easy to use right out of the box. I even found myself using it well in a semi dark room after the first day with almost no hunt and peck. I am sure others well find it as easy and convenient as I.

good product but a little flimsy
00:00:00 05-15-2011
A great product and works fantastic. The materials are light, though, so i'm not sure how well it will stand up to rough treatment.

love, love, love this remote! it was super simple to set up (i sweated it at first, but it all worked out perfectly). it is simple to use and i don't know what i did without it before. i purchased the refurbished unit and have had no issues with charging...i can leave it off the charger for several days and it still has juice.

Wireless Remote Control Switch
00:00:00 05-04-2011
We were looking for a universal remote to link our sound system, tv, satellite, and game system without using four remotes. This one did just that. With quick and simple setup you'll be one click away from it all. I dock it most nights so I'm not sure how long the battery goes, there is a "battery life" symbol on the screen. I left it off the charger for several days and it still worked just fine. The only thing that would make this better is a page button, much like the one on my cordless phone.

Great Remote
00:00:00 04-22-2011
Great remote for a complicated setup. The only drawback I've ever had with this 880 remote (I've used 3 across several systems) is that it is slow in inputting numbers from the favorites menu (Media button). I've tried to turn the delay time down, but it doesn't speed up the input.

Powerful and easy to use remote
00:00:00 04-13-2011
After initial setup, "activities" automate the traditional multi-step sequence of button presses getting the DVD player, the TV, and the stereo system to work together. Remote came in plain packaging with all accessories in new condition, but my volume up key is not as sensitive as the other keys and requires a really hard press.
