I have a 2133 and was getting fed up of the light being on all the time. So I opened up the unit and cut the lead to the motion switch and VOILA! Now it will not turn on until I press a button. This saves the batteries and possibly the screen's life.

Instructions:

1) Using the right phillips screw driver, remove the battery cover and the batteries.

2) Remove the 4 screws in the aluminum portion of the remote.

3) Very carefully remove the plastic bottom of the unit by carefully pulling and rocking.

4) Remove the top. Do this to make the board extraction easier and re-assembly easier.

5) Remove the aluminum body and lift off the plastic battery tray. This makes it easier to access the SW1 with a soldering iron.

6) Locate SW1 on the circuit board. It is located on the middle right side of the remote when the IR leds are pointing up.

7) The switch is a little metal box with a black plastic on the bottom end. The goal is to cut the top lead to the circuit board.

8) With a soldering iron, carefully heat up the solder on the top metal end of the switch (not the plastic end!) and remove as much solder as possible by tapping the remote on its side so that the solder falls off.

9) When enough solder has been removed, simply clip the wire and move it or the switch slightly to the right. DO NOT TRY TO UNSOLDER THE JUMPER AS THIS WILL MAKE RECONNECTION VERY RISKY. You could burn through the screen. Should you ever want to re-enable the moton switch, simply solder the ends together.

10) Carefully reassemble the unit in this order:

- Carefully slide the top part of the remote on, being VERY careful to properly slide the screen under the housing lip and aligning the IR LEDS so as not to break them off.

- Slide on the aluminum housing and snug into the top part being VERY CAREFUL that the screen slides under the housing lip.

- Slide on the bottom part being VERY CAREFUL that the screen slides under the housing lip.

- install the batteries, screw on the battery door and confirm that everything works.

- reinstall the 4 body screws and your done!

Note: Some people may not have have a soldering iron or even the desire to slolder in their remote. You can just try to cut the wire with a close cutter but this will be really hard because if your unit is like mine, there will be a lot of solder on it.

Has anyone been able to adjust or disable the keypad sensor for the URC-9960? I am hoping someone can share tips on how to open up the remote. I am willing to disable the auto-sensing feature entirely to save on batteries. A step-by-step, just like skripo's topic "Kameleon (2133) over sensitivity fixed!", will be greatly appreciated!

The URC-9960 opens up in the same manner as all other OFA remotes, but it's very tight, I think it's the hardest OFA remote to open out of all of them.

Here's the procedure:

Thanks Robman, this was exactly what I was hoping for. We got the remote open, and clipped the wire connected to the sensor. Now, I am happy to report that the remote is working much better now and I imagine that battery life will be longer.

While you have it open you should solder in a 6-pin JP1 connector. Unlike regular OFA remotes, there aren't any holes in the PCB on the URC-9960, there are just pads, so what I do is: put some flux on the pads, then stand a 6-pin connector on the pads, then solder them in place. Finally, I put a load of hot glue around the connector to make sure it stays put.

Is the URC-9960 worth buying?

Most "power users" don't think so. But then some people have actually bought them and use them. It does have a lot of restrictions, and there have been many complaints about over-sensitivity and quick battery drain.

I guess it's kinda like manure. Anyone can buy manure, but not everyone has a perfect use for it. For some it's a unwanted byproduct, so they hope to sell it, or find some other means of disposal. So, those sellers need and hope for buyers.

Whether it's "worth buying" is very personal and subjective, something only YOU can determine or decide. For me it might be a worthless POS, However for you it may well be the best thing since peanut-butter.
