Safety Information  

 

 

IMPORTANT SAFETY INFORMATION 

Read Information

 — All the safety and operating information should be read before the amplifier 

is plugged in. 

Follow Information

 — All operating and use information should be followed. 

Retain Information

 — Retain the safety and operating information for future reference. 

Heed Warnings 

— All warnings on the amplifier & in the operating instructions should be heeded. 

Ventilation

 — The amplifier should be situated so that its location or position does not interfere 

with its proper ventilation.  The amplifier should never be placed near or over a radiator or heat 
register.  The amplifier should not be placed in a built-in installation such as a bookcase or cabinet 
that may impede the flow of air through the ventilation openings. Do not place this amplifier 
directly on carpeted floors. 
 

Non-Use Periods

 — Amplifiers that are left unattended should be turned off via the rear panel 

switch to extend the life of the tubes and conserve energy. 

Grounding or Polarization

 — Do not defeat the safety purpose of the polarized or grounding-type 

plug.  A polarized plug has two blades with one blade wider than the other blade.  A grounding 
type plug has two blades and a third grounding prong.  The polarized wide blade and the third 
prong are provided for your safety.  If the provided plug does not fit your outlet, consult an 
electrician for replacement of the obsolete outlet. 

Power Cord Protection

 — Protect the power cord from being walked on or pinched particularly at 

plugs, convenience receptacles and the point where they exit from the amplifier. 

Water

— Do not use the amplifier near water. 

Cleaning

 — Unplug the amplifier from the AC outlet before cleaning.  Use only a dry cloth to clean. 

Object and Liquid Entry 

— Never insert objects of any kind through the openings of these 

amplifiers, as they may touch dangerous voltage points or short-out parts that could result in a fire 
or electric shock.  Care should be taken so that objects do not fall and liquids are not spilled into 
the amplifier through openings in the enclosure. 

Servicing 

— Do not attempt to service these amplifiers yourself, as opening or removing the 

bottom cover WILL expose you to dangerous high voltages.  Refer all servicing to Bob Carver LLC. 

Damage Requiring Service 

— These Amplifiers should be serviced by Bob Carver LLC when: 

 

A power supply connection or a plug has been damaged or 

 

If liquid has been spilled into the amplifier or objects have fallen into the amplifier or 

 

The amplifier has been exposed to water or moisture or 

 

The amplifier does not appear to operate normally or exhibits a marked change in 
performance or 

 

The amplifier has been dropped or the enclosure damaged.
