Question about Polar F11 Heart Rate Monitor

1 Answer

How to change battery on Sports Instruments ECG 3? Not the chest strap battery but the unit that fits on the wrist. Sports Instruments recommends sending it to them or it can be changed by or jeweler but I want to do it my self, save the $15-20 plus possible shipping (to SI), and wait for SI to send it back in two or three weeks.

I just replaced my ECG 3 battery. It's a CR2025 battery for the watch. You have to remove the watchband first, by pushing in on the pins that attach the band to the watch case. It helps to have a very small screwdriver because you have to push on a tiny ring. Once the pin is out of the hole in the watch case, wiggle the band a little until the pin comes all the way out. Don't let it pop out across the room! Remove the other side of the band the same way.

The back is held on with 4 small Phillips screws. Take them all out and remove the back. You'll see the battery which is held by a stainless retainer clip. Removing this clip is tricky: you have to stick a pin or needle in the middle of one end of the clip and very gently pry the clip out by moving the needle toward the middle of the battery. It's hard to even see what you're doing without a magnifying glass. The remaining side of the battery retainer clip should come off easily. Remove the battery and put the new CR2025 in with the + side facing out. Replace the battery retainer clip. Replace the back, being sure that it's positioned so the tiny gold spring on the back of the watch will contact the uninsulated spot on the stainless back. Also be sure you haven't somehow moved the black O-ring seal out of position, which would let water in. Screw the 4 Phillips screws back in and reattach the band. Your watch should be running again!

How do you reset cardio track watch


u may have started wearing a Polar F11 Fitness heart rate monitor to help you keep track of your pulse during cardiovascular exercise. The monitor consists of a strap with electrodes that you attach to your chest, which transmit heart rate data to a receiver worn on your wrist like a watch. The wrist unit stores data and settings that you can customize, such as your weight, height and target heart rates. However, you may wish to reset the unit and start over with new settings. You can reset your Polar F11 by following a few easy steps.
Instructions

    • 1 Press any button to activate the Polar F11 Fitness heart monitor unit.
    • 2 Press all buttons on the Polar F11 Fitness heart monitor simultaneously, except the "Light" button. There are five buttons and the "Light" button is at the top left side of the unit. Continue to hold the buttons until the display fills with digits.
    • 3 Press the "OK" button, which is located on the right side of the unit in the middle of the up and down buttons. The Polar F11 Fitness heart monitor will reset.

Can you change the battery in the chest strap for polar f6


There are two types of straps for Polar:

1) hard rubber/ solid - These can not have the battery changed.

2) soft strap with connector in middle - these you can change the battery.

If you have the soft strap, it will have a small hard around 3 inch long block that "snaps" onto the strap to connect it. These have a battery compartment. Turn it around and you will see the outline for the battery compartment. These are not always easy to open, and the batteries are a little harder to find. Take it into any watch repair and they should be able to pop a new battery in for you pretty easy.

There is a link on my tips and tricks page to get manuals for Polar products, the T-31 wearlink is the product we are talking about, it has the how to change the battery and battery type.

Doesn't synch with heart monitor


Hmmm. Trick one without seeing the unit.. The most obvious is that the battery in the chest strap is dead. If it's one of the sealed ones then the whole chest strap will need to be replaced, if not then it'll be a standard watch battery. I should be clear from the chest strap if the battery can be replaced.
If both batteries are ok then try to turn on the Forerunner, put on the chest strap(make sure to lick the back of the sensor or dip it in water to make a solid connection, strange I know but that's what they reccomend). Then hold your wrist wearing the Forerunner a couple of inches from the sensor on your chest, sometimes needs to be for 30 seconds or so.. All going well that should do it.. Beyond that you're into the software in the Forerunner itself and that has to go back to Garmin..

Sports instruments pro9 watch strap problem


The half that goes into the buckle (ie the half with the holes) broke in two, leaving about 5 holes on the intact part--too short to fit my wrist. I extended the remaining portion with a strip of nylon webbing that I had on hand (it pays to be a pack rat!), sewing it on using the existing holes. I used a soldering iron to make holes in the webbing.

Sportsline SX Combo heart rate monitor not connecting


How old is the unit? Make sure you are wetting the electrodes on the strap and it is snug around your body and in contact with skin just below your chest if female under your sports bra. If that doesn't work the battery in your strap may not be good.

HRM troubleshoot


A HRM is a training tool that helps you do cardiovascular (CV) training correctly, neither too hard, nor too easy. It’s almost like having a personal coach on your wrist! Every HRM comes in two parts: 1. An elasticated chest strap which contains a pair of sensors that detect and transmit your heart rate. 2. A wrist worn receiver that receives the signal from the chest strap and displays your heart rate. The receiver may also have additional functions and display other information depending upon the HRM model chosen. Both the chest strap and receiver are battery operated.

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!

Can Link watch with Heart Monitor


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. 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 (5) put the battery back in the chest strap (if it's not already in - it's possible to push the button without removing the battery) (6) hold both of the electrode to create a signal (probably not necessary - it usually links immediately). 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.
