In addition, the transformer base plate must be secured for transportation to avoid excessive constraints on the silent blocks
isolating the chassis from transformer vibrations. This is done by the insertion of three security screws on the bottom of the unit.
Failure to do so will void the warranty as it may cause the silent blocks to tear up and the heavy transformer module to move
inside the A1, resulting in severe damages to all A1 components. Do not forget to install these screws for transportation and to
remove them at installation of the unit in its new location.
Finally we recommend to remove the adjustment spikes and to put them into the A1 box for transportation. Indeed, vibrations
during transport may cause the adjustment spikes to move from their fully retracted position. There is risk of scratching the
installation base if the spikes are not fully retracted when installing the unit.
2.6 Cleaning
Use a soft, dry towel or cloth for cleaning. Never use any solvent or liquids as they may damage the surface treatment or
penetrate inside the unit.
2.7 Maintenance and service
The A1 power amplifier contains no user serviceable parts. Do not try to open, modify or repair your A1 by yourself. This will void
any warranty. Your A1 power amplifier must be checked by a qualified technician in any of the following cases:
• The unit is not functioning properly
• The mains cable or the power cord receptacle is damaged
• The unit has been dropped to the floor or presents external damage
• The A1 power amplifier has been exposed to liquids (such as rain) or unknown substances
