4. SAFETY AND MAINTENANCE
PRECAUTIONS
Never operate the player with either the bottom or top covers removed.
Do not open the amplifier !
There are no user serviceable parts inside. For technical assistance or
product service please refer to your Authorised Dealer or to a Unison
Research authorised Service Centre.
Do not spill liquid into the amplifier !
If liquid should be accidentally spilled into the amplifier remove the mains
plug from the wall socket immediately and seek assistance from an
authorised Service Centre before attempting to operate it again.
Before inserting the mains plug into the wall socket ensure that the
switch on the amplifier is in the “OFF” position.
If you do not intend to use the amplifier for a long period of time we
strongly recommend you unplug from the mains at the wall socket.
Valve replacement should be carried out using only valves of the same
type and matched in pairs.
The
Unico CDPrimo
uses one valve type ECC82 (12AU7). The amplifier
has been designed for maximum valve life: in laboratory tests 1500 hours
life have been exceeded.
IMPORTANT!
Before attempting valve replacement make sure that the amplifier is
switched off and allow sufficient time for the valves to cool. Remove the
mains power cord from the amplifier. If in doubt your Authorised
Dealer or Service Centre will be able to assist with this operation.

.
Cleaning has to be done after switching off the device and allowing the
amplifier to cool down.
Use a soft dry cloth.
Do not use solvents or alcohol-based detergents.
Do not rub hard on the screen-printed legends on the top cover.
Never operate the amplifier when covered! Adequate ventilation is
essential at all times!
