Steve – not sure if the 305 is considered old technology now but I still like it a lot. My HRM quit working – changed battery – didn’t work. Then checked google before I tried anything else. The bending of gold tab did the trick for me. Thanks!

YEAH!!
thanks for this thread. I am here in South Africa, from Holland and my 305 HR died on me. Watch was fine. Took a new battery, no luck. Bending the gold helped! Very excited to go out for my pm workout later!

Another poorly heart rate strap here!! I’ve tried all the above and still no luck. I have borrowed another strap which works with the watch so it is defo the strap that is poorly.

It was working fine until this morning and then after 400m it gave up. If I take out and replace the battery it has occassionally looked like it is going to work and always shows 72 for a few seconds before giving up again.

Any Ideas?

Amazing! I got the 305 for Christmas and the HR was flashing an X over the icon. I tried so many trouble shooting things and decided to see if there was something on the web. I read your post, adjusted the medal prong out just a bit and immediately the monitor starting working. THANK YOU SO MUCH!!

Another in a long line of thank you’s. Mine stopped working about 2 months ago and I finally sat down to see if I could fix it. Did a quick search, found your write-up, and my HRM is back up and running. Thanks!

Got the 305 two days ago. Worked brilliantly – except for the HRM. This was rather upsetting as I need to monitor my heart rate. Thankfully, I came across this site. I am not absolutely certain what I did, but slight fiddling with the pin seems to work!

Will be able to check it thoroughly two days hence when I go for my run.

But thanks a ton!!

Thanks heaps! Worked like a charm, bend the gold thing and reset the unit. Easy! I’ve been without for so long…. Can’t believe it was such an easy fix. Thanks for the post!

Haven’t used 305 for a while so decided to fit a new battery but the HR monitor failed to work. Having read all posts here gave new battery a good rub with a paper towel, as Ronan recommends above, fitted battery in the monitor + side up, fitted monitor to chest, started 305 and BINGO all started working again! Thanks to all for their tips.
