CARE AND MAINTENANCE
POWER DOWN
The APERIO amplifier / DAC generates high-voltages and runs warm in normal use. Given this,
it should be powered down when not in use for extended periods or left unattended.
CLEANING
The amplifier / DAC unit should be cleaned with a soft, dry cloth. Never use anything abrasive
as this may damage the metal finish. Do NOT use liquid / aerosol cleaners.
The headphones should be cleaned with a soft, dry, micro-fiber cloth. This is also the case for
the leather parts. Do NOT use any liquid / aerosol cleaners as they may damage the leather
and cause failure of the pads.
Failure to follow these instructions will invalidate your warranty.
REPLACING EAR PADS
Ear pads may need replacement after years of extended
use or if inadvertently damaged. Replacement pads are
available from your dealer or via the Warwick Acoustics
website.
To remove the old pads, carefully insert a finger into the
ear cup so that it is behind the ear pad as much as
possible. Take care not to damage the webbing or
electrostatic panel! Then, with your thumb, firmly grasp
the ear pad, and pull it away from the ear cup.
Place the new pad on the ear cup with the seam in the
leather at the BOTTOM of the ear cup. Then, carefully,
press firmly all around the pad to attach it. Check that
the ear pad is firmly seated and tight to the ear cup all
around its perimeter. This is essential to ensure an air-
tight seal and correct bass response.
Note: If your headphones are under warranty, we are more than happy for you to send your
headphones back to us and we will replace the pads and return to you within an agreed
timeframe.
