When does which LED light up/flash and why?

Why doesn't my ROCKSTER seem to be working?

Check the power supply:
- What is the charge level of the battery? If it is almost empty, connect your ROCKSTER to a mains socket immediately.
- Is your ROCKSTER switched off or without power?
- Check the power cable and the socket.
- If everything is OK with the battery, mains cable and socket, but the ROCKSTER still remains switched off, then check the mains fuse:
  
  Fig. 1: Remove the mains cable. Carefully pull out the fuse switch on the mains connection socket.
  Fig. 2: Push out the old fuse downwards. A replacement fuse is located in the removed compartment and is inserted and the holder is pushed back.
Check the volume:
- As a test, increase the volume with the MAIN VOLUME control on the rear panel and the mixer (on the top panel) with the VOLUME controls for channel 1 and VOLUME for channel 2.
- If your source device is connected via Line In, then carefully increase the volume on this device.
Check the Bluetooth connection
- Is the ROCKSTER selected as the output device on your source device/smartphone/player? Have you selected the correct connection, i.e. the channel used? If you want to play your music via Bluetooth® on Channel 1, select" ROCKSTER-1", for Channel 2 select "ROCKSTER-2" as the output device.
- Is the Bluetooth® connection disturbed? Other wireless systems (e.g. cordless phone or microphone, Wi-Fi), but also crowds of people can interfere with the connection. Place the ROCKSTER and/or source device in a different location for testing purposes.
Check the INPUT:
- If no sound comes out of the ROCKSTER even though all the controls on the mixing console are set correctly, it may still be because the Input Select switch is set to Master IN. In single mode, this should be set to Channel 1/2

What can I do if the ROCKSTER is humming?

Cause: The ROCKSTER is connected to a different circuit to the rest of the system.

Solution: Connect the ROCKSTER and source device/preamplifier to the same circuit.

Cause: The humming is caused by electrical interference.

Solution: Connect all devices via a power strip.

Cause: The humming is caused by a multiple socket outlet.

Solution: Use another multiple socket or connect the ROCKSTER directly to the wall socket.

Can the ROCKSTER also be operated from a car socket (12 V)?

The ROCKSTER can be operated indirectly via a car socket by connecting a standard 12V to 230V voltage converter between the car socket and the ROCKSTER power cable.

How can I install/remove/replace the ROCKSTER battery?

You can find instructions for installing/removing or replacing the ROCKSTER's internal battery here.

What is the best way to store the ROCKSTER?

If you are storing your ROCKSTER for a longer period without a mains connection (e.g. in winter), prepare it accordingly:

Connect your ROCKSTER to the mains and allow the battery to charge fully (see "The battery" on page 27 in the operating instructions).
Remove the battery from the battery compartment and store it in a cool, dry place at 10 to 20 °C. Protect the battery from humidity and direct sunlight.
Store the ROCKSTER in a dry place at a storage temperature of +10 to +40 °C. Protect your ROCKSTER from direct sunlight.

For longer periods of storage without use, we recommend fully charging the device at least once a month.

What can I do if the battery does not charge and/or discharges very quickly?

Instructions for resetting the internal central control unit (MCU reset) of the ROCKSTER can be found here.

What can I do if the wheels are broken?

If necessary, we can repair the damage by installing a new base plate for a fee. You can find more information here: ROCKSTER: Casters broken off - what now?
