AUSTRALIAN MONITOR ACM250 Operating Manual Download Page 6

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

2. Read all documentation before operating your
equipment. 
Retain all documentation for future refer-
ence.

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 operate the 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 re-
ceptacles, 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.

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

10. Power down & disconnect units from mains volt-
age 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 other 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 com-
pletely enclosed rack. If the unit is used in an extremely
dusty or smoky environment, the unit should be peri-
odically “blown free” of foreign matter.

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 paral-
lel- or series-connect an amplifier output with any
other amplifier output.

Audio Telex Communications Pty Ltd is not respon-
sible 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 an-
other “hot” (red) output!

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

20. Service Information Equipment should be ser-
viced 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
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.
