I found this on the internet......

In the battery compartment there’s a gold contact that touches the top of the battery (+ve) which was in a position that would never make contact with the battery. I bent it out slightly, made sure the battery was seated correctly (i.e. flat) and as if by magic my heart rate appeared on the large Garmin display!


Also found this..........

I Have had the same problem couple of times (and forgotten each time how I solved it). I figured it out just now and this is what I did.

1) turn on unit and put on heart monitor (make sure battery is good and wet heart strap)
2) using the mode button navigate the menus to: Settings: General: Accessories: Heart Rate Monitor
3) Once in the Heart Rate Monitor option make sure "Yes" is selected and then use the arrow buttons to highlight "Restart Scan" . Press the enter button to rescan for your heart monitor. (I had to rescan twice)
Go back to the main monitor screen to see if you are recieving heart rate signals.

I am not sure why a manual rescan needs to be done every time but it would be nice if Garmin fixed this issues in a unit software update (my unit has software version 2.80

Hope this helps......

How do i change a battery in a garmin 305
Hi David!

From your Owners Manual (Page 54)
http://www8.garmin.com/manuals/984_OwnersManual.pdf

REPLACE THE HEART RATE MONITOR BATTERY

"The heart rate monitor contains a user replaceable CR 2032 battery...
Locate the circular battery cover on the back of the heart rate monitor. Use a coin to twist the cover counter-clockwise until it is loose enough to remove. Remove the cover and replace the battery. Be careful not to lose or damage the o-ring gasket on the cover. Then use a coin to twist the cover back into place."

Hope this helps.

How do I enable my EFX 544 to give my heart rate while wearing my polar heart rate chest strap?
If the EFX 544 has polar Heart Rate attach to the upper electronics your chest strap should be transmitting and the unit should be receiving. If your chest strap is more than 3 yrs old usually the battery will die and needs to be replaced or you have a defective receiver and will have to be replaced

Heart rate writst watch won't work
Hi,
Here is the manual for your heart rate monitor:
http://www.omronhealthcare.com/img/shop/hr-100c---2003-hr100cinst-rev-a.pdf
The size of your wrist shouldn't matter, because you can actually mount the monitor to a bike handle, so you don't have to be wearing it at all. It's just acting as a receiver, displaying the info. Are you wearing the transmitter belt, is it positioned correctly, and tight enough? Are you putting water or gel on the backside of the transmitter so that you get good conduction and contact? Is the transmitter belt within 20 inches of the monitor receiver display?
The transmitter battery might be low. If so, the symptom would be that your readings can be erratic. I know you said that you just bought it, but batteries can be low in new products. ..How many times have you bought a new digital watch only to find that it had a low battery...You can replace the battery in the transmitter with a lithium 3v battery #CR2032. Do you see a low battery indicator? If so, the display (receiver) battery also needs replacing and it uses the same battery as the transmitter.
Hope it helps, please let me know.
Thanks

MY heart rate is way off in the wind on my edge 305. It works fine on the trainer and at low speeds. But on a windy day or when going downhill it picks up 50-75 bpm.
Maybe change the battery of your heart device. When going weak, the heart rate is not correct

Isn't receiving/showing my heart rate
Hi there,

First thought is the battery in the wearlink is dead if you're getting no icons or lights flashing. Luckily the wearlink is designed to have the user change the battery. Ideally your local Polar outlet will sell battery kits (app €12), these come with a new battery, seal and door and take a minute to change. Here in the shop we routinely offer to change it 'cos customers can be a bit wary of taking it apart, but it's easy.
If the shop doesn't stock them they should be able to order it for you..

Timex heart rate monitor does not keep correct BPM. I changed the battery, now the heart rate hovers in the 30' and 40's, never getting to the correct BPM
Make sure the back of the watch is spotless and your skin isn't too dry.
