FAQs

1. What type of battery does my Acumen Heart Rate Monitor use?

Most of current models use battery CR2032. Also, the battery type is written on the back cover of each watch.

2. I changed the battery in the watch. Now the watch is frozen. What should I do?

You could press and hold all buttons on your watch at the same time until the display goes blank. Then release to reset the circuitry. (This is how you perform the “Global Reset” on your watch.)

3. After putting on my chest belt, I didn’t get the heart rate reading immediately.

Putting a few drops of water between the rubber straps and your skin for best operation.

4. My Heart Rate Monitor failed to work after changing the battery.

Please check to see if the battery is in correct with positive sign (+) facing out. Also make sure that back cover for the Watch is placed with word “Acumen” showing at the top.

5. My heart rate monitor is giving an abnormal heart rate reading during exercise?

There are several reasons for an abnormal reading:
- The contact between the skin and the electrodes of the transmitter is not strong. Improve contact by moistening the electrodes/skin before beginning your exercise. As you exercise, your body produces sweat which will help to ensure a good signal. Make sure that the elastic strap for your transmitter is not too loose. A secure strap will ensure good contact.
- Scaring (chest scars) can also cause a poor signal. Adjust the transmitter into a position where the signal improves.
- Wear and tear of your transmitter can also prevent good contact. You can purchase a new transmitter by giving us a call at 1-800-852-7823 or by sending an e-mail to customerservice@acumeninc.com.

6. I had the watch for 1 to 2 years and this is my second time changing the battery in the unit. How long shall the battery last?

Estimated battery life with normal use (1 hr / day, 7 days / week):
- Lithium CR2050 battery – 2 years
- Lithium CR2032 battery – 1.5 years
Over use of the backlight can also shorten the battery life.
