- Your Performance Monitor (PM) is warning you that the batteries are too low, but you think the batteries are OK.
- You’re using D cell batteries in your PM, and the battery life seems short.
This resolution applies to PMs installed on the following equipment:
- Model D Indoor Rower
- Model E Indoor Rower
- Dynamic Indoor Rower
Take the following steps to determine whether the problem is with the generator cable or the battery.
- Remove all batteries from the PM.
- Ensure the “tach” (generator) cable is plugged in firmly and all the way.
- Row/ski hard on your machine.
- If the PM comes on and stays on while you are rowing/skiing, then at least part of the generator is working. Proceed to step 4.
- If the PM does not come on, then generator cable needs to be replaced, and you can stop following this diagnostic procedure.
- Install fresh D cell batteries in the PM. The PM should power up.
- Set the language and date (the year, at minimum).
- On the PM Main Menu select More Options, then Utilities, then Product ID.
- Look at the Model type. Make sure it is set to D or D/E.
- If using a PM4, look at the firmware version and ensure your PM is running the most current version. If you have old firmware, the rechargeable battery will not work at all after a while. Your PM4 will work fine after updating the firmware and fully charging the battery pack.
- Press Menu | Back until you reach the Main Menu.
- Select Just Row/Ski.
- Start rowing/skiing:
- If the numbers begin counting, then the generator appears to be working. Proceed to step 10.
- If the numbers do not begin counting, stop this diagnostic procedure and replace the generator before proceeding.
- Stop, press Menu|Back while the flywheel is still spinning, and wait for 30–60 seconds. If you receive a low battery message, stop this diagnostic procedure and replace the generator.
- If using a PM4, remove the D cell batteries and install the rechargeable battery pack.
- If using a PM4, plug the PM into a USB port of a computer overnight to charge battery. Note: Concept2 recommends turning off your computer’s Hibernate or Sleep modes; otherwise, you may not get a good charge.
This resolution applies only to monitors in use with Model A, B, or C Indoor Rowers.
Under normal circumstances, a set of Alkaline D cell batteries should last for about 350 hours of operational time. If you find this is not the case, take the following steps:
- Check your firmware version: On the Main Menu select More Options > Utilities > Product ID. Running the latest version of the firmware may extend the life of batteries, as newer firmware uses the microprocessor more efficiently.
- Observe the performance monitor after rowing/skiing. The monitor should turn off within six minutes of the time you stop rowing (except when plugged into a computer, using PM4 racing, or during certain types of intervals). If it is not turning off within that timeframe, please contact Concept2 for assistance.
- Check the battery level: On the Main Menu select More Options > Utilities > Battery. Once the battery level gets down to about 80%, the battery percentage should not go down by more than 1% per day. If it does, there is probably damage to the circuit board and the unit should be replaced. In a health club, the most likely cause of this is spraying the monitor with cleaning chemicals.
