Ensure that children do not detach any small parts (e.g. knobs or the like) from the product. They could swallow the pieces and choke! Never let children play unattended with the product.

CAUTION!
Possible hearing damage.
Making music for a prolonged period and at high volume can cause hearing damage. Avoid playing the unit at full volume, especially when using headphones.

NOTICE!
Operating conditions
This device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and strong vibrations.
Only operate the device within the ambient conditions specified in the chapter ‘Technical specifications’ of this user manual. Avoid heavy temperature fluctuations and do not switch the device on immediately after it was exposed to temperature fluctuations (for example after transport at low outside temperatures).
Dust and dirt inside can damage the unit. When operated in harmful ambient conditions (dust, smoke, nicotine, fog, etc.), the unit should be maintained by qualified service personnel at regular intervals to prevent overheating and other malfunction.

NOTICE!
Possible damage by leaking batteries.
Leaking batteries can cause permanent damage to the device. Take batteries out of the device if it is not going to be used for a longer period.

NOTICE!
Possible property damage by magnetic fields.
Loudspeakers produce a static magnetic field. Therefore, maintain an appropriate distance to devices that can be adversely affected or dam‐ aged by an external magnetic field.

NOTICE!
Possible staining
The plasticizer contained in the rubber feet of this product may possibly react with the coating of your parquet, linoleum, laminate or PVC floor and after some time cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the floor, but use felt-pad floor protectors or a carpet.

Scope of delivery

Setting the height

The endpin to adjust the height of the instrument is fully retracted in delivery condition and fixed with wing screws. Turn the wing screws counterclockwise to loosen the fixation and the endpin.

Drag out the endpin so far that the instrument can be played at the desired and for you ergonomically correct and comfortable height. Then tighten the wing screws clockwise to fix the endpin in this position.

Tuning the strings

Now tune all strings with the pegs using a tuner device to the correct pitch (usually C-G-D-A from low to high).

Connections and controls

CAUTION!
Possible hearing damage
Making music for a prolonged period and at high volume can cause hearing damage. Avoid playing the unit at full volume, especially when using head‐ phones.

NOTICE!
Risk of breakage, possible deformation
When placing the instrument with the fret board down, there is a risk of damaging the fingerboard and the tailpiece. Avoid any compressive load on the rear of the instrument, if it is placed for the assembly or for service work with the fret board down on a solid surface.

Before connecting amplifiers or headphones, the volume controls of the cello and the equipment to be connected must be set to “minimum”. This avoids loud crack noises when switching on.

Connecting and inserting the battery

The instrument is operated with a 9 V block battery. The battery is not included in the scope of delivery. Open the battery compartment cover on the back of the instrument. Clamp the power cable with the correct polarity to the battery. Insert the battery into the battery compartment and close the battery compartment cover. It must audibly click into position.

NOTICE!
Risk of fire due to incorrect polarity.
Incorrectly inserted batteries may destroy the device or the batteries. Ensure that proper polarity is observed when inserting batteries.

NOTICE!
Possible damage by leaking batteries.
Leaking batteries can cause permanent damage to the device. Take batteries out of the device if it is not going to be used for a longer period.

Connecting audio devices

The connector for audio devices (3.5 mm jack socket) is located on the rear side of the instrument.

Connecting headphones

The connector for head phones (1/4″ jack socket) is located on the rear side of the instrument.
When using headphones with 3.5 mm mini jack, you need an appropriate adapter.

Adjusting Volume and Tone

The controls to adjust the volume [Volume] and the tone ([Treble] and [Bass]) are located on the back of the instrument.

Maintenance

Changing strings

Strings are subject to a natural aging process, which is also affected by the frequency of use of the instrument. Changing the strings is recommended if the sound quality of the instrument decreases audibly. Always replace the complete set of strings (strings of 4/4 length) and always go string by string. In this way you avoid a strong temporary bending of the neck due to reduced string tension. The bridge also remains in the correct position and does not have to be readjusted.

Proceed as follows to change the strings:

1. For example, loosen the run-down C string from the capstan of the machine head and from the tailpiece.
2. Thread the new C string into the tailpiece, pull it over the bridge into the capstan bore of the machine head.
3. Hook the string end to the capstan and tighten the string tension slowly. At the first windings, pay particular attention that the string is taut to the mechanics.
4. Make sure that the string is running correctly through the grooves of bridge and nut at the upper end of the neck.
5. Slowly increase the string tension until the correct pitch is reached. Use a tuner or a pitch pipe for reference.
6. Proceed in the same way with the G, D and A strings and then tune all strings again successively to the correct pitch. Note that the string tension will drop a little and the instrument needs to be retuned several times until the strings stay in tune.

Battery change

1. Replace the inserted battery if necessary (weak output signal) or at regular intervals.
2. Open the battery compartment cover on the back of the instrument. Remove the battery and unplug the connection cable from the battery terminals.
3. Clamp the power cable with the correct polarity to the new battery. Insert the battery into the battery compartment and close the battery compartment cover. It must audibly click into position.

NOTICE!
Risk of fire due to incorrect polarity
Incorrectly inserted batteries may destroy the device or the batteries. Ensure that proper polarity is observed when inserting batteries.

Plug and connection assignment

Introduction

This chapter will help you select the right cables and plugs to connec t your valuable equipment in such a way that a perfect sound experience is ensured. Please note these advices, because especially in ‘Sound & Light’ caution is indicated: Even if a plug fits into the socket, an incorrect connection may result in a destroyed power amp, a short circuit or ‘just’ in poor transmission quality!

Unbalanced transmission

Unbalanced transmission is mainly used in semi-professional environment and in hi fi use. Instrument cables with two conductors (one core plus shielding) are typical representatives of the unbalanced transmission. One conductor is ground and shielding while the signal is transmitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference, especially at low levels, such as microphone signals and when using long cables.

1/4″ TS phone plug (mono, unbalanced)

1/4″ TRS phone plug (stereo, unbalanced)

Three-pole 1/8″ mini phone jack (stereo, unbalanced)

Cleaning

Clean the instrument and especially the strings after playin g with a dry, soft, lint-free cloth. Stubborn dirt can be removed with a slightly dampened cloth.
Never use cleaners containing alcohol or thinner.

Protecting the environment

Disposal of the packaging material

For the packaging, environmentally friendly materials have been chosen that can be supplied to normal recycling.
