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

  1. Unscrew the Patient Response Button (this will create a hole behind your device).  The screw is found at the midpoint of the button.20150709_154441.jpg
  2. The most common failure is the disconnection of the jumper cable to the circuit board (seen below) 20150709_154452.jpg
  3. Ensure that you do not lose the four compenents (1 screw, 2 housing pieces, 1 spring).
  4. Super glue the rubber cable back togethermaa4e0
  5. Cover the glued pieces with heatshrink and heat to securely wrap the rubber pieces back together.MQ9F82
  6. Slip the cord back into the bottom slot and use the housing and reconnect the cable to the jumper.
  7. 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! 4zNgBMzm1Qi4

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!


  1. THANK YOU SO MUCH FOR THIS SIMPLE FIX!!! Patient response buttons have surged in price (thanks, Zeiss), so this will help us a lot.

  2. Amazing. Just fixed two of these bad boys with the advice on this page. Saved me a load of time and money.

  3. This just saved my day! I had spent 20 minutes trying to get the clicker apart. There was a piece of plastic covering the screw so we did not know there was a screw to take it apart! There were no instructions in the manual either! So frustrating! Thank you so much!! I appreciate you taking the time to make this post!
