- Upgrade OP-Z to the latest firmware, here.
- Plug in the unit to a computer with the OP-Z usb cord.
- With the unit plugged in and turned off, you should now be able to see the track 16 LED blinking yellow. This means that the OP-Z is trying to wake up the battery.
- Once the LED starts blinking green, the battery has successfully been waken up.
- Please leave the OP-Z charging until full, this may take a while since the battery is very low.
Q: What if yellow LED does not turn green?
Wait for 20 minutes. If it has not waken up after 20 minutes, it may help to try again. Plug out the cable and plug it in again. It may also help to remove the battery, plug in the cable and then insert the battery. This may take a few tries.
Q: Can I turn on the unit while it is trying to wake up the battery?
Yes, you can turn it on and off as much as you want.
Q: Can I pull out the usb cord as soon as the LED is flashing green?
No, it will probably take at least an hour before the battery is back to normal charge. If you plug it out too early, you may have to start over again.
Q: Does it matter how I charge the unit?
Yes, whatever you plug it into needs to have sufficient power. Plugging it straight into your laptop's USB-A or USB-C outlet is verified to work. Using USB-hubs may reduce the power.
We recommend to use our own 75cm USB-C or USB-A cables, since we know they are working. Long cables may not work.
Q: What if the LED is solid green, and the battery indicator is 100%, but still the unit can not run on battery?
- Make sure you are on the latest firmware.
- Try plugging the battery in and out a few times.
