Concept2 Forum

I have a Model B and just upgraded to a PM5. Was so excited to get my workout in. I attached the monitor and got a message that said :

Tach Cable Message : Ground Wire

Attention
The sensor wire is damaged. Please contact Concept2 for repair or replacement.

Since I can’t really do anything until Monday - can someone confirm that the part they are talking about is the pickup wire? Seems to me that’s the only “wire” - it plugs into the PM.

Thanks for any input.

First thing to do is check the firmware version and date code.

If the firmware isn't V168 (or V30 if you didn't get it direct from Concept2).

If its date code is before 14th April 2014 then it may need the battery cover replacing.

If it's not firmware or battery cover then pick up the phone on Monday and call Concept2 at 1-800 245 5676.

Thanks for the reply.
Firmware version is 168 and Hardware version is 634.
Will make the call first thing on Monday.
