Using the  Silver Cube

Do not touch the Silver Cube under the following circumstances:

- If you hear thunder, remove the power plug from the AC outlet as soon as possible. If you fear a lightning hit and 
the Silver Cube has been connected to an AC outlet, do not touch the power plug. Otherwise you may receive an 
electrical

 

shock.

- Do not attempt to modify this equipment. Otherwise, fire or electrical shock may result. Warranty is void on 
modified devices. Exceptions: dip switch settings, fitting of custom input load when done carefully by a skilled 
person (trained technician). Normally this is your dealer.

- If you think the Silver Cube needs to be checked for maintenance or repair, consult your dealer.

- Do not place a container of water or any small metal object on top of the Silver Cube or the external power 
supply. If water is spilled or if the metal object gets inside, fire or electrical shock may result. This applies to vases,  
pottet plants, glasses, cosmetic bottles, medicine, etc. Do not change the setting of the dipswitches with any tools 
that consist of metal.

- Do not damage, process, bend, twist, stretch or heat the power cord. If the cord is damaged,fire or electrical 
shock may result.

- When you are connecting other audio devices to the Silver Cube make sure that you first turn off the power to all  
devices to be connected. Refer to the user´s guide for each device and use the specific cable for connection.

- Set the volume levels of all devices to minimum before connecting the Silver Cube to your actual setup and to the  
AC outlet. Otherwise, an extremely loud noise could damage your loudspeakers or even your hearing.

- If you plan not to use the Silver Cube for a long period of time (such as when you are on vacation), remove the  
power plug from the AC outlet. Otherwise, a fire could possibly result.

- If any abnormality occurs while using the Silver Cube, remove the plug from the AC outlet. In this case first shut  
off the power amplifiers or turn down the volume controls and so on to avoid possibly damaging transients

- If you notice any abnormality - such as smoke, smell, noise, etc. - remove the plug from the AC outlet. Confirm  
that the abnormality is no longer present, then consult your dealer for repair. If you continue using the Silver Cube 
under abnormal conditions, fire or electrical shock may result.

- If a foreign object or water enters inside the equipment, remove the Plug from the AC outlet and consult your 
dealer for repair. If you continue using the Silver Cube under this condition, fire or electrical shock may result.

- If the power cord is damaged (for example if it is cut or if the core wire is exposed), ask your dealer for a  
replacement. If you continue using the Silver Cube under this conditions, fire or electrical shock may result.

- If the Silver Cube or the external power supply is dropped, or if the case is damaged, remove the plug from the AC  
outlet and consult your dealer. If you continue using the Silver Cube under abnormal conditions, fire or electrical 
shock may result.
