Frequently Asked Questions

How do I use ErgStick?

ErgStick is a dongle that plugs into the USB Plug on PM3 / PM4 & PM5 monitors and allows you to transmit via Bluetooth the data you create whilst rowing on the Concept2 Rowing Machine.

What apps work with ErgStick?

At the moment the only app that works with ErgStick is Float on iOS.

How do I turn the ErgStick on?

The LED will only come on if the ErgStick is charged. Every 15s the ErgStick checks if it is plugged into a Concept 2 display. If the display is on then after a while the Green LED will flash.

You can then connect the app.

The LED light does not come on?

Your ErgStick is not charged. The battery will last for 6-7 days on standby. Use the adapter provided and plug it into a USB plug.

When you plug it in a green red light will come on. When the battery is fully charged then it will turn green. If you leave the ErgStick plugged in for a long time then the green light will switch off.

What happens if my phone runs out of battery during the session?

The session will not be recorded as the phone is required to store the data. Please ensure that your phone is sufficiently charged for the session.

Do I need to charge the ErgStick?

The ErgStick does not get any power from the Concept2 displays. The USB is a peripheral and as such we can not charge the device from the PM monitor. Use the USB adapter provided to plug into any USB plug.

It should take about 6  hours to gain a full charge. The battery lasts for 6-7 days on standby and should give 6-8 hours of use depending on the monitor you use.
