NIKE wa0056-002 battery - Rio Nike PSC Communicate (14 Channels) 2-Way Radio

I am very sorry to hear that news, just dreadful :>(

I was trying to find out who actually makes this watch, but there is no data. Normally you send to the maker and they repair it. My late wife bought me a Seiko, and although I live in Canada, I send it to the UK where it was purchased and where the service centre is for servicing. you could ask Nike who was contracted to produce it? My guess is Casio, because it has the Casio look to it.

One thought I have is that the battery that was put in it was the wrong type or it was inadvertently replaced with a battery out of another watch that came in for repair. I would have another battery put in it and see what happens. It is actually a collectible watch.

There are a few ideas which battery is the correct one

contact your local jeweler they may be able to determine size and voltage by measurement of battery compartment.

I’m happy to assist further over the phone at https://www.6ya.com/expert/howard_977676954994c5b2

Yes you need to replace the battery. I had the same problem. Replaced the battery on mine and everything is fine now.

You can't change it yourself without doing damage. You will need to send into Nike or more accurately an authorized nike watch repair center that is close to you hopefully.

Nike customer service or a google search for authorized nike watch repair in XXX-city will get one close to you.

does it have a slot on the back ? usually Nike watches are made to easily replace the battery usually with a nickle slot on the back or screws on the corners. The batteries they have are usually common 2806 or similar coin sized batteries. It will say on the back of the battery .

Most jewelry or watch repair shops can easily replace these batteries. if you bought the watch within a year , have receipt and something is broken. You can send it back to nike to be repair for free. It is done by parsec located here http://www.nikewatchrepair.com/.

Thank you for contacting FIxYa.
I would read the NIKE support site before deciding to do any battery changes on your own. As a retail jeweler/watch service tech I would HIGHLY recommend you doing what they suggest:

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!
