vetrik-Who told you you had to have an unused test stick to reset the monitor? I've never had to do that. I just reset mine with no stick involved.
I bought mine from ebay, so I wanted to reset the monitor completely to "like new" and wipe off any previous information it had on it, which is different than resetting it for a new cycle. I used these instructions to do that, and they called for an unused test stick. It was a waste of a stick though, considering how expensive they are - I'm glad you don't have to use one every month! I read afterwards that some people used that stick for the first testing day, which doesn't really matter that much anyway - unfortunately, I read that too late!
1. Remove the plastic cap from one end of a clean-unused-test-stick and snap the cap onto the other end of stick. Insert the test stick into the test stick slot of the monitor. The beveled corner on the insertion end of the stick must face in toward the monitor. THE STICK MUST SNAP INTO PLACE TO PERFORM PROPERLY. THE MONITOR SHOULD NOT BE TUNRED ON UNTIL STEP 2.
2. Press and hold the "M" button. Continue pressing the "M" button while turning the monitor on. NOTE: Do not take finger off the "M" button until these directions say to to do so in Step 5.
3. The screen will show the "remove the test stick" symbol(a flashing test stick with an arrow pointing right). Conitnue pressing "M".
4. Keep pressing the "M" button and in about 20 seconds, you will see a screen full of symbols. The screen will also display these symbols when you initially turn the montior on for the FIRST time. This indicates the memory is now cleared of all prior data.
5. Remove test stick first and then QUICKLY release your finger from the "M" button. The memory should now be cleared.
6. Your screen should display a flashing "M" and one or two dashes. If it does not, it will probably show a "1" and an "M" in a non-flashing mode. If so, you will need to repeat all steps of this process. This procedure may take several times before you successfully reset the unit to its"new" state.
7. Start using the monitor on CD 1 as per the instruction booklet.
