Precautions
Danger
This sign reminds users of “dangerous voltage” on the
product.
Caution
This sign reminds users of important instructions
attached to the product.
Safety
guideline
In order to prevent electric shock, this equipment plug
shall not be used as conductor to extend power supply
line.
Do not block the equipment’s ventilation opening or put
other equipment on it.
Safety
guideline
Protect this equipment against rainwater or moisture so
as to avoid fire or electric shock.
Unpacking
After removing the amplifier from the carton, inspect for any exterior
damage to the unit. If damage is noted, notify the carrier at once so that a
claim can be justified. Save all packing material. This is important when
the claim is processed.

2
Ventilation
To offset heat generated by the unit, it is necessary to provide ample
ventilation around the unit. Avoid blocking or impeding the ventilation holes
on the unit. To prevent unnecessary problems, install the unit in a place
free from any vibrations, direct sunlight, humidity or dust circulation.
Prevent liquids or other materials to enter cabinet
If the unit gets wet or any foreign material enters the amplifier cabinet,
immediately disconnect the AC power cord and consult your dealer or
qualified technician.

when the apparatus has been damaged in any way such as power
supply cord or plug is damaged, liquid has been spilled or objects have
fallen into the apparatus, the apparatus has been exposed to rain or
moisture, does not operate normally, or has been dropped.
Apparatus shall not be exposed to dripping or splashing and no objects
filled with liquids, such as vases, shall be placed on the apparatus.
WARNING –To reduce the risk of fire or electric shock, do not expose
this apparatus to rain or moisture.

This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
Network Security
Placement
Please put the device in a safe place, lock the cabinet and keep the
keys well.
The access control system of the central control room should be under
strict management.
Any person except authorized maintainer is forbidden to disassemble
or change parts of device.
