I would think it is the sensor circuit in the watch. When you replaced the battery did you activate the processor all reset for the watch? I do not know on your model where or how this would be activated.

Electronic watches normally have a reset procedure for when the battery is changed. Very important the watch's processor reset is performed after changing the battery. This is not any of the user readings reset. This is a reset for the watch's processor and system. It is sometimes a contact that has to be shorted out with the jeweler's screwdriver, or it is a contact that has to be shunted, or etc., depending on the model. Maybe if you call the support for the watch they will tell you this. Normally they do not like the user opening the watch.

did u ever figure out how to get the retaining clip?

I haven't seen this watch but I suspect the thin metal peice is the battery retainer. If so look carefully to see if it clips over the module at provably several points. If so gently prise them up to release the retainer. Wipe off new battery and install the correct way up. Replace retainer ensure it is correctly clipped in at all points. Set about recalibration process. If it doesn't have clips perhaps it has screws. If so remove them etc. Pleae rate this solution.

First you have to assume the battery that comes with your HRM would be new - keep in mind that it may be stored in the warehouse for many moons.
Given that, open and take out the battery - that should make a hard reset on the HRM itself. Restore the battery and try the manual pairing again.
The heart icon should pop up again.

Otherwise, you have to suspect the battery is low and need to be replaced.

Good luck

Hi,

I've been having the same problem. I couldn't pair my footpod, but my heart rate monitor was working. I've only had the 50 for about eight weeks.

I reset the watch, holding view mode and Start/Stop at the same time.
This didn't do any good.

I swapped the battery in the HRM with that in the foot pod. The foot pod synched the HRM didn't.

Solution duff battery. I'd change yours it will probably do the trick.

Hope it helps

The Timex Ironman manual and website says to take the watch to a repair facility. Nope! Do it yourself!

How to replace the battery in a Timex Ironman watch:

This is easier if you remove one of the rubbery wrist bands.

1. Take note of the position of the metal back cover. You'll need to reinstall it exactly as you see it in order to hear the alarm.

2. Remove the four screws that hold the metal back cover, and pry off the cover.

3. There is a round metal clip that holds the battery in place, covered with a transparent plastic cover which likely says, "Unlatch to remove battery". Within the center of each clip, there's a small opening just large enough for a straight pin to be inserted. A jewelers screwdrive won't work - use a straight pin. Insert a straight pin into the tiny opening at the edge of the clip, and wiggle it. The clip should release. You'll only need to unlatch one side of the battery retaining ring.

4. Gently pry up the batter retaining clip, then pry up the battery. Insert new battery.

5. Replace the clip.

6. Insert a flat blade screwdriver into a slot which has two "electrodes" or pins - they need to be shorted with the screwdriver to reset the watch. Just touch the screwdriver blade across the two pins to short it.

7. Reinstall the back cover but be sure to position the cover so the alarm sounding place ( a small disc attached to the inside back cover) will reside over the sounding spring.

8. Insert screws.

Nike Triax CV10 - Successful HRM reset 7 November 2008
 
I had real problems too. Even after repeatedly following the known reset steps everyone else is posting up. Here’s how I got mine going, please forgive the mind bogglingly tedious detail…
 
First make sure you’re using new good quality batteries. I used Maxell’s, bought in 10’s from Hong Kong on ebay – no problem.
 
Second, and this is the ESSENTIAL bit…move right away from the computer and any other electromagnetic sources before carrying out the known reset…
 
Third, follow the known reset steps below, adjusted to what worked for me…
 
If you press all four buttons of your Nike HRM it will reset. Next time you go to "RUN" mode, it will show "HRM LINK" error. You will now need to "hard reset" the unit.
 
Nike made a late change to add a "hard reset" to the chest strap. To re-link (re-initialise) the watch you'll need to open the battery door on the chest strap, and use a paper clip (or the equivalent) to push the small gold button in the battery area. There should be a small sticker in the battery compartment that points to the reset button.
 
The re-initialisation steps for the Nike C10 and CV10 digital HRM's is:
 
(1) reset the watch
(2) open the battery door on the chest strap
(3) move the watch to RUN mode
(4) press the reset button in the chest strap battery area without removing the battery
 
Tip - I agree with the suggestion to use a pin or needle and definitely do it with the battery in the hrm.
Tip – Thumb holds battery to stop it from pinging out, other hand performs jiggle with pin until the link is made (it links straightaway if you jiggle it just right!)
 
(5) replace chest strap battery cover…and smile!

If you can't link the hrm do as detailed in the following link If you press all four buttons of your Nike HRM it will reset. Next time you go to "RUN" mode, it will show "HRM LINK" error.

My suggestion is to use a very thin needle and do it with the battery in the hrm. Eventually, Nike will either eliminate the hard reset or update the manual to include this info.
