Just bought a ScubaPro M2 (mantis 2)

My M2 arrived yesterday. It included a wireless transmitter and wireless Heart Rate Monitor. I will be using for the first time starting on Tuesday in an 8 week NAUI advanced scuba course. Anybody have any helpful tips or knowledge about the M2? I can’t seem to get the heart rate monitor to connect to the computer.

It should be the same as in the Galileo. Make sure the HR is turned on in the settings, and that the chest strap is tight.

Thanks. I figured out how to turn it on in the setting still no go. So I decided to replace the HRM battery, it was a basic cr2032. After that it worked perfect. I assume it must have just died sitting on the shelf.
