Hi all,
I got an FR 965 along with the HRM Pro-Plus chest strap a couple of months back. From time to time, I notice that the watch connects to the chest strap, even when I'm not wearing the strap! When this happens the strap is usually about 10-15 feet away from me. I notice this easily as the watch starts displaying hilariously high heart rate between 215-220!
Recently the watch started complaining about "Heart rate monitor battery is low" (again when I wasn't wearing the strap). This would happen around frequently enough to bother me (say around every 15 min?). Exasperated, I finally turned off the strap under "Sensors and Accessories" on the watch.
Is there an issue with the strap or even the watch?
As a side note - I thought the strap battery were generally expected to last at least a year :( . I workout ~6 times/week (for about an hour each session), so I'm definitely not a power user.
