Low battery symptoms
- The red light blinks rapidly followed by the trainer turning off.
The red light does not come on, even though the Spoke Magnet is properly aligned with the Speed Sensor.
- The Bluetooth or ANT+ signal drops repeatedly, despite being in range.
Charging the Halcyon
When fully charged, the STAC Zero Halcyon’s powerful battery provides power for:
- 10 hours wireless riding.
- 1 year on standby.
To prolong the life of the battery we recommend you charge your trainer using a micro-USB cable regularly, or leave it plugged in during use. Unplug the cable gently.
Tip: the little prongs on the USB cable face down (away from the calipers) when plugged in.
You can view your battery life in STAC Control Panel. It will appear in the top left portion of your screen when your trainer is connected.
When batteries are very low, the red light will flash and the trainer will auto-power off. 10-15 minutes of charging a low battery should allow you to finish a workout. To fully re-charge the trainer (recommended), plug in overnight.
When charging, a red light near the charging port will turn on. It will turn off again to indicate the trainer is fully charged.
Charging the Powermeter
How often should I charge my Powermeter?The Powermeter has a powerful battery, and should only need to be charged every 4 or 5 months. Just make sure you charge it fully before you put it away for the season, because fully draining the battery isn't good for its longevity.
How can I see my the battery level?Connect to the trainer with the STAC Control Panel app, available for free on App Store or Play Store, to see the battery level.
Powermeter charging instructions
Charging port location
Charge for 8 hours or overnight, using a standard Micro USB cable. Remove the cable gently.
You can charge the powermeter from a computer or laptop, or from an outlet using an adaptor. An outlet is preferable, as laptops will generally stop providing charge to other devices when they go to sleep.
