PM4 Frequently Asked Questions

Rower/Monitor Interchangeability

Does the PM4 use the same formulas as the PM3?

Yes, the PM4 uses exactly the same math to determine pace and output, and the internal metal flywheel design itself is unchanged—so the times are interchangeable with that of the PM3.

Can a PM4 be installed on a Model D, C, B or A Indoor Rower?

Yes, it is possible to retrofit a PM4 to a Model D, C, B, or A Indoor Rower. These are available as retrofits. To order, click Shop above or call 800.245.5676 (U.S./Canada only).

Can the same PM4 unit be used on all Model rowers?

No. Each PM4 is configured to work on the specific model of indoor rower on which it will be installed. Additionally, Concept2 has set up specific kits for each scenario to ensure you receive any additional hardware necessary for mounting a new style monitor to the flywheel on your model indoor rower. Please contact Concept2 or the authorized dealer in your country for more information.

Getting Help with Your PM4

I have a problem with my PM4. What do I do?

Please refer to the PM4 Troubleshooting page, which contains answers to many common problems. If the problem persists, or if you did not find the answer, please contact us by phone at 800.245.5676 or email at rowing@concept2.com (US and Canadian customers only. All other customers should contact their dealer.)

PM4 Batteries

What type of batteries does the PM4 use?

The PM4, when purchased with a Model D or Model E Indoor Rower, comes equipped with a rechargeable battery pack. The recharge rate depends on the usage pattern of the rower: the more and harder you row, the more quickly the PM4 charges. The rechargeable battery pack works only when a PM4 is installed on a Model E Indoor Rower or a Model D Indoor Rower manufactured from December 1, 2006–present. All PM4s are also equipped to use two D-Cell (IEC LR20) batteries. Retrofit PM4s for Model D/C/B/A will come shipped with D Cell batteries.

If I choose to use batteries, how long will the D cell batteries last using a PM4 on my Model D?

The D cell batteries have about 300 hours of life.

I would like to retrofit the PM4 to my Model C/B/A Indoor Rower. How long will my D cell batteries last using a PM4 on my model rower?

Approximately 300 hours.

Is there a way to find out how much battery power I have left?

Yes. On the PM4, go to More Options, Utilities, and then Battery. The amount of power left will be displayed as a percentage for D Cells. It is hard to determine the capacity left in a rechargeable battery, so the indications will be “Low”, “Very Full” or anywhere in between.

Is there any way to get better battery life from the PM4 on older model indoor rowers?

Yes. You can power your PM4 from your PC or Mac's USB port. Alternatively, you can use the AC Adapter available for the PM4.

Third Party Software and Computer Compatibility

Is there third party software available for the PM4?

The software company Digital Rowing has developed a Windows based program called RowPro that works with the PM4. For more information about this product and what it does, please visit digitalrowing.com. Please use their most recent release, Ver 2.003 or higher. This is not a Concept2 product.

Can I develop software for the PM4?

You cannot develop software for the PM4; however, you can develop software for your computer that will talk to the PM4 from your computer. A Windows programmer's interface guide is now available. To obtain a copy of the programming materials, please visit the Concept2 Forum and become a member. Once you become a member, you will find some forums for software development. Information about downloading the software development kit can be found on the PM Software Development page.

I have a Macintosh computer. Is there software available for me?

Yes. Starting with Version 4.0, the Concept2 Utility is PM4 and Mac-compatible.

I have a Linux computer. Is there software available for me?

Not at this time. The Linux drivers do not currently operate properly for the PM4 to communicate with these systems. If you are a software developer, please go to our Software Developer Forum.

Wireless Features

I’m installing PM4’s near WiFi: How do I prevent them from interfering?
  1. Try to configure your networks with the lowest 802.11b/g channel numbers available (that is, Channel 1–6). The ANT transmissions overlap around channel 10–13, and to a lesser extent channel 7–9.
  2. Keep access point antennas as far away as is conveniently possible.
