• Exposure to extremely high noise levels may cause a permanent hearing loss.
• Individuals vary considerably in susceptibility to noise induced hearing loss, but nearly
everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient
time. The U.S. Government´s Occupational Safety and Health Administration (OSHA) has
specified the following permissible noise level exposures:
Duration Per Day In Hours Sound LeveldBA, Slow Response
8
6
4
3
2
11/2
1
1/2
1/4 or less
• According to OSHA, any exposure in excess of the above permissible limits could result in
some hearing loss.
• Ear plug protectors in the ear canals or over the ears must be worn when operating this
amplification system in order to prevent a permanent hearing loss if exposure is in excess of
the limits as set forth above. To ensure against potentially dangerous exposure to high
sound pressure levels, it is recommended that all persons exposed to equipment capable
of producing high sound pressure levels such as this amplification system be protected by
hearing protectors while this unit is in operation.
• Fuses: Replace with IEC 127 (5x 20 mms) type and rated fuse for best

• The unit has been built by HK AUDIO
in safe working order. To maintain this condition and ensure non-risk operation, the user
must follow the advice and warning comments found in the operating instructions. The
unit conforms to Protection Class 1 (protectively earthed).
• HK AUDIO ® ONLY GUARANTEE THE SAFETY, RELIABILITY AND EFFICIENCY OF THE
UNIT IF:
• Assembly, extension, re-adjustment, modifications or repairs are carried out by
®
HK AUDIO or by persons authorized to do so.
• The electrical installation of the relevant area complies with the requirements of IEC
(ANSI) specifications.
• The unit is used in accordance with the operating instructions.
• The unit is regularly checked and tested for electrical safety by a competent technician.
WARNING:
• If covers are opened or sections of casing are removed, except where this can be done
manually, live parts can become exposed.
• If it is necessary to open the unit this must be insulated from all power sources. Please
take this into account before carrying out adjustments, maintenance, repairs and before
replacing parts.
• The appliance can only be insulated from all power sources if the mains connection is
unplugged.
• Adjustment, maintenance and repairs carried out when the unit has been opened and is
still live may only be performed by specialist personnel who are authorized by the
manufacturer (in accordance with VBG 4) and who are aware of the associated hazards.
• Loudspeaker outputs which have the IEC 417/5036 symbol (Diagram 1, below) can carry
voltages which are hazardous if they are made contact with. Before the unit is switched
on, the loudspeaker should therefore only be connected using the lead recommended by
the manufacturer.
• Where possible, all plugs on connection cables must be screwed or locked onto the
casing.
• Replace fuses only with IEC127 type and specified ratings.
• It is not permitted to use repaired fuses or to short-circuit the fuse holder.
• Never interrupt the protective conductor connection.
• Surfaces which are equipped with the "HOT" mark (Diagram 2, below), rear panels or
covers with cooling slits, cooling bodies and their covers, as well as tubes and their covers
are purposely designed to dissipate high temperatures and should therefore not be
touched.
• High loudspeaker levels can cause permanent hearing damage. You should
therefore avoid the direct vicinity of loudspeakers operating at high levels.
Wear hearing protection if continuously exposed to high levels.

MAINS CONNECTION:

• The unit is designed for continuous operation.
• The set operating voltage must match the local mains supply voltage.
• The unit is connected to the mains via the supplied power unit or power cable.
• Power unit: Never use a damaged connection lead. Any damage must be rectified by a
competent technician.
• Avoid connection to the mains supply in distributor boxes together with several other
power consumers.
• The plug socket for the power supply must be positioned near the unit and must be easily
accessible.
PLACE OF INSTALLATION:
• The unit should stand only on a clean, horizontal working surface.
• The unit must not be exposed to vibrations during operation.
• Keep away from moisture and dust where possible.
• Do not place the unit near water, baths, wash basins, kitchen sinks, wet areas, swimming
pools or damp rooms. Do not place objects containing liquid on the unit - vases, glasses,
bottles etc.
• Ensure that the unit is well ventilated.
• Any ventilation openings must never be blocked or covered. The unit must be positioned
at least 20 cm away from walls. The unit may only be fitted in a rack if adequate
ventilation is ensured and if the manufacturer's installation instructions are followed.
• Keep away from direct sunlight and the immediate vicinity of heating elements and
radiant heaters or similar devices.
• If the unit is suddenly moved from a cold to a warm location, condensation can form
inside it. This must be taken into account particularly in the case of tube units. Before
switching on, wait until the unit has reached room temperature.
• Accessories: Do not place the unit on an unsteady trolley, stand, tripod, base or table. If
the unit falls down, it can cause personal injury and itself become damaged. Use the unit
