Troubleshooting
Find your problem below — device first, then the firmware updater.
The device
Section titled “The device”The status lights double-blink red fast
Section titled “The status lights double-blink red fast”The self-calibration after switch-on didn’t succeed. The usual cause is the device being moved, rocked or turned while the status lights pulsed blue — movement disturbs the measurement it uses to find its balance point.
Fix: switch the device off, place it on its holder on the cradle, and turn it on again. Leave it still until the blue calibration pulse ends.
The rocking assist doesn’t kick in
Section titled “The rocking assist doesn’t kick in”The device waits for about five steady swings at a normal rocking pace before joining in.
Fix: rock the cradle evenly and not too fast or too slow. The green blinking speeds up as it counts your swings. It also won’t start while the device is being carried or the motion is jerky.
The rocking stops by itself
Section titled “The rocking stops by itself”That’s a safety feature, not a defect: the motor stops when the motion fades or stops, or the device is bumped or picked up.
Fix: give the cradle a fresh push to start again.
Pro tip: some combinations of cradle and surface work better with the rocking mode, some with the continuous mode. Try what works best for your case.
A button press only makes the lights flash red
Section titled “A button press only makes the lights flash red”The device is telling you that press can’t work right now — you’re already at the highest/lowest level, or it’s busy switching modes.
Fix: wait a moment, or check which level you’re on via the button lights.
No music plays
Section titled “No music plays”Check:
- Are there any songs on the device at all? Put new songs on with the music manager.
- Tap Music once — playback doesn’t start on its own.
- Turn the volume up: hold Music and tap Plus.
The firmware updater
Section titled “The firmware updater”Whatever went wrong: your device is safe. Unplugging it never causes damage, even in the middle of an update.
The updater page is available in English and German (“EN”/“DE” toggle at the top right); here we quote the English messages.
“Please use Chrome or Edge on a computer”
Section titled ““Please use Chrome or Edge on a computer””Your browser can’t talk to the device. Open the updater in Google Chrome or Microsoft Edge on a Windows, Mac or Linux computer — phones, tablets, Safari and Firefox won’t work.
The device isn’t in the browser’s list
Section titled “The device isn’t in the browser’s list”- Check the USB cable is fully plugged in at both ends.
- Try a different USB port or cable (some cables are charge-only and carry no data).
“Couldn’t read the device”
Section titled ““Couldn’t read the device””The browser found a device but couldn’t talk to it. Unplug the device, plug it back in, and click “Try again”.
“That doesn’t look like a ROCK your BABY”
Section titled ““That doesn’t look like a ROCK your BABY””You may have picked the wrong entry in the browser’s list. Click “Try again” and make sure you select your ROCK your BABY.
“No firmware available yet”
Section titled ““No firmware available yet””The newest firmware isn’t ready on the server right now. Try again in a few minutes.
“Couldn’t reach the update server”
Section titled ““Couldn’t reach the update server””Your computer couldn’t contact the update server. Check your internet connection and try again.
“The update did not finish”
Section titled ““The update did not finish””Something interrupted the update — a wobbly cable is the usual cause. Your device is safe: unplug it, plug it back in firmly, and start over.
The page suddenly shows “One more step”
Section titled “The page suddenly shows “One more step””Not an error: on devices with very old firmware, the update can’t be sent directly over the USB cable yet. Just follow the instructions on the page. After that one update, future updates run without the extra step.
The music manager
Section titled “The music manager”The same applies to updater.cullatecinternal.com/music/ as to the updater: Chrome or Edge on a computer, and unplugging never causes damage.
“Firmware update needed”
Section titled ““Firmware update needed””Your device’s firmware is too old to receive music over USB. Do a firmware update first, then open the music manager again.
“Lost the connection to the device”
Section titled ““Lost the connection to the device””The device stopped responding — a wobbly cable is the usual cause. Unplug it, plug it back in, and click “Try again”.
“… was skipped”
Section titled ““… was skipped””The page didn’t transfer a file and tells you why:
- “… only MP3 files can be played” — convert the song to an MP3 file first.
- “… not enough free space on the device” — remove another song first.
- “… the device already holds the maximum of 6 songs” — more than 6 songs don’t fit; remove another song first.
Still stuck?
