Metrics - Patient Response Button Fix
A Patient Response Button (aka "The Clicker") for our Zeiss FDT went out again at our office and I decided to see what the problem was. When I took it apart, I found that it was a very simple fix. In this post, I will show a quick fix to get your Patient Response Button back up and running. A quick fix if you’re waiting for the replacement from Zeiss ($35 plus shipping). Disclaimer: Although this is a VERY simple electronic fix, please do so at your own risk. I will not be held responsible for any damage caused by using this fix.
The Problem: the most common failure of the button is caused from normal wear and tear and occurs when the rubber end-piece separates and causes the jumper to separate from the jumper cable (displayed below).
What you need
- Heatshrink (works wonders on temporary frame repairs also) - a half inch piece of the second from the biggest size should be perfect
- Lighter or other heatsource
- A Phillips Screwdriver
What to do
- Unscrew the Patient Response Button (this will create a hole behind your device). The screw is found at the midpoint of the button.
- The most common failure is the disconnection of the jumper cable to the circuit board (seen below)
- Ensure that you do not lose the four compenents (1 screw, 2 housing pieces, 1 spring).
- Super glue the rubber cable back together
- Cover the glued pieces with heatshrink and heat to securely wrap the rubber pieces back together.
- Slip the cord back into the bottom slot and use the housing and reconnect the cable to the jumper.
- Align the spring with the button mechanism, reassemble, and screw to secure. Ensure you holding the housing together when you screw it in. And that's it!
This only took about 5 minutes to do. I've done it twice and both remotes were tested and working properly. Let me know if this helps!
