CAUTION

There are no user serviceable parts inside this amplifier. Removal of
the cover by unauthorised personnel may invalidate warranty and will
result in exposure to lethal high voltage and current. In the unlikely
event of a fault developing within the E1300 refer servicing to qualified
personnel only.

USER RESPONSIBILITY

Loudspeaker Damage

Many loudspeakers can be easily damaged or destroyed by overpowering,
especially with the high power available from a bridged amplifier. Always
check the loudspeaker continuous and peak power capability. Even if the
gain is reduced by using the amplifier front panel attenuators, it is still
possible to reach full power output, if the input signal level is high enough.

Shock Hazard

Power amplifiers are capable of producing hazardous output voltages. To
avoid electrical shock, do not touch any exposed loudspeaker wiring when
the amplifier is operational. See page 15 for correct connection of
loudspeakers.

Radio Interference

A sample of this product has been tested and complies with the limits for
the European Electro Magnetic Compatibility (EMC) directive. These limits
are designed to provide reasonable protection against harmful interference
from electrical equipment. This amplifier uses radio frequency energy and if
not used or installed in accordance with these operating instructions, may
cause interference to other equipment. Compliance with the (EMC)
directive does not automatically guarantee non-disturbance of susceptible
equipment in close proximity to this amplifier.

If the amplifier is suspected of causing interference, this can be easily checked
by powering the unit "ON" and "OFF", and observing the disturbance. The
user can correct the interference by one or more of the following steps:

1. Increase the distance between the equipment.

2.  Connect the power cable to a socket on a different circuit from that to

which the affected unit is connected.

3. If a radio receiver is affected (normally only AM receivers are affected);

Re-orientate the antenna.

4.  Check if the affected equipment complies with the EMC limits for

immunity, (CE-labelled). If not, address the problem with the
manufacturer or supplier. All electrical products sold in the EC must be
approved for immunity against electromagnetic fields, high voltage
flashes and radio interference.
