1. Save the carton and packing material even if the
equipment has arrived in good condition. Should you ever
need to ship the unit, use only the original factory
packing.

2. Read all documentation before operating your equipment.
Retain all documentation for future reference.

3. Follow all instructions printed on unit chassis for
proper operation.

4. Do not spill water or other liquids into or on the unit,
or operatethe unit while standing in liquid.

5. Make sure power outlets conform to the power
requirements listed on the back of the unit.

6. Do not use the unit if the electrical power cord is frayed
or broken. The power supply cords should be routed so
that they are not likely to be walked on or pinched by
items placed upon or against them, paying particular
attention to cords and plugs, convenience receptacles,
and the point where they exit from the appliance.

7. Always operate the unit with the AC ground wire
connected to the electrical system ground. Precautions
should be taken so that the means of grounding of a piece
of equipment is not defeated.

8. Mains voltage must be correct and the same as that
printed on the rear of the unit. Damage caused by
connection to improper AC voltage is not covered by
any warranty.

14. Do not remove the cover. Removing the cover will expose
you to potentially dangerous voltages. There are no user
serviceable parts inside.

15. Do not drive the inputs with a signal level greater than
that required to drive equipment to full output.

16. Do not connect the inputs / outputs of amplifiers or
consoles to any other voltage source, such as a battery,
mains source, or power supply, regardless of whether the
amplifier or console is turned on or off.

17. Do not run the output of any amplifier channel back into
another channel’s input. Do not parallel- or series-connect
an amplifier output with any other amplifier output.
Australian Monitor Inc is not responsible for damage to
loudspeakers for any reason.

18. Do not ground any red (“hot”) terminal. Never connect a
“hot” (red) output to ground or to another “hot” (red)
output!

19. Non-use periods. The power cord of equipment should be
unplugged from the outlet when left unused for a long
period of time.

20. Service Information Equipment should be serviced by
qualified service personnel when:

A. The power supply cord or the plug has been damaged.

B. Objects have fallen, or liquid has been spilled into the
equipment

9. Have gain controls on amplifiers turned down during
power-up to prevent speaker damage if there are high
signal levels at the inputs.

10 Power down & disconnect units from mains voltage
before making connections.

11. Never hold a power switch in the “ON” position if it
won’t stay there itself!

12. Do not use the unit near stoves, heat registers,
radiators, or ther heat producing devices.

13. Do not block fan intake or exhaust ports. Do not operate
equipment on a surface or in an environment which may
impede the normal flow of air around the unit, such as a
bed, rug, weathersheet, carpet, or completely enclosed
rack. If the unit is used in an extremely dusty or smoky
environment, the unit should be periodically “blown free”
of foreign matter.

THIS SAFETY INFORMATION IS OF A GENERAL NATURE AND MAY BE SUPERSEDED BY INSTRUCTIONS CONTAINED WITHIN THIS MANUAL

C. The equipment has been exposed to rain

D. The equipment does not appear to operate normally, or
exhibits a marked change in performance

E. The equipment has been dropped, or the enclosure
damaged.

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,

DO NOT REMOVE COVER (OR BACK),

NO USER SERVICEABLE PARTS INSIDE,

REFER SERVICING TO QUALIFIED SERVICE PERSONAL.

WARNING!

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK

DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE.

Caution:

This symbol is intended to alert the user to the presence
of uninsulated “dangerous voltage” within the products
enclosure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.

This symbol is intended to alert the user to the presence
of important operational and maintenance (servicing)
instructions in the literature accompanying the
appliance.

To prevent electric shock do not use this (polarised) plug
with an extension cord, receptacle or other outlet unless
the blades can be fully inserted to prevent blade exposure.
To prevent electric shock, match wide blade of plug to
wide slot, fully insert.
