I changed the battery in the watch. The watch works fine, however the watch dosn't pick up the pulse from the belt. I know the belt is oK because I have a Polar pickup on my treadmill and it picks pulse up fine from the belt

Try manualslib.com or MFG website, or email their customer service.

Is the sensor properly spaced from the magnet on the spoke? Will the sensor pick up slow revolutions but not fast ones. Do you know that some of the sensors have two batteries in them, one on the top and one on the bottom, and both need to be changed at the same time?

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.

If Heart Rate is being displayed on the equipment in the gym, but not your watch, then your chest strap is transmitting fine, but the watch is not recieving the signal.

It is not uncommon that when a battery is changed outside of a polar authorized service center that something can happen to the internal electronics. I would suggest you send the watch into Polar and have them take a look. if you have had the watch less than 2 years they will most likely take it under warranty and correct the issue, at the very least they have equipment to test and diagnose both the watch and strap, although it sounds like your HR strap is fine since you are getting HR on the machines.

ok place watch on window ledge inside house ..when you go to bed make sure its sat on a book with nothing else in its way except the glass window, the signal should be picked up by your watch between midnite and 3am that is sent from one of 5 world wide beacons.if this does not work have battery refitted and make sure the repairer AC's the watch this has to be done any repairer will know what you mean..

pulse reader will not work after battery change

Try re-pairing the belt pod with the wrist-watch computer. Below text comes from page 37 of the T6c users manual.

If you replace the belt battery or are having troubles with the signal reception, you need to re-pair your belt with your Suunto t6c.

To re-pair the belt:
1. Remove the belt battery
2. Push the (new) battery into the compartment positive side down.
3. In your Suunto t6c, enter the settings menu and enter GENERAL.
4. Scroll to PAIR with [Lap +] and [Light -] and enter with [Mode].
5. Scroll to HR BELT with [Lap +] and [Light -].
6. Activate pairing with [Mode].
7. Put the battery in with the positive side up and close the cover.

The really nice thing about your watch is that when you need a battery, the watch gives you a 30 day notice by having the second hand do what I call " a triple step" where the watch keeps time, but youe second hand goes 3-4 steps real fast and then stops. Please take your watch to a reputable watch repairman, because your watch has a Cartier movement , and NOBODY but Cartier has the parts for your watch if somebody who dosn.t know what they are doing messes it up. If you have anymore problems feel free to ask me anytime . I LOVE EBELS!!!!

Even you change a new battery with desame size and volts not working.The problem is in the terminal where going to put the battery.The terminal had a dirt or a film residue that comes out from the battery,you better clean terminal by scratching the old film,the lying down terminal is negative,,the side terminal is positive you better observed polarity if happen inter change the battery side it will not works.If not working, even you clean already terminal,short the terminal connection for 3 seconds,If you have a flourescent with a ballast,put your watch lying where there is strong vibration for five minutes, your watch works 100% txt me whatever the result so i know it's ok.
