SAFETY PRECAUTIONS
The AVTRONICS PPA-300 sound system is supplied with a detachable power cable with an lEG
female connector and a male AC connector. Depending on the territory in which the PPA-300 system
is purchased, the power cable will be supplied with one of a number of male AC connectors in order to
accommodate the different safety and code requirements of specific countries. All AC cables supplied
with PPA-300 products are three pin grounded type.
Under no circumstances should the ground pin be disconnected or removed.
Your PPA-300 System converts voltage 115V and 230V by switch. When travelling abroad with the PPA-300 system,
as a standard precaution, always check the local voltage and set the voltage selector switch located adjacent to the
socket on the rear of the mixer amplifier to the appropriate operating range. This check must be performed before
connecting the power cable. The AVTRONICS PPA-300 has two range settings: 115V or 230V.
Failure to select the appropriate voltage range will cause the unit to go into protect mode, void any warranty and
may cause damage to the unit. For example, The United States of America is standardized at 120 V / 60 Hz, Japan
operates on 100 V / 50 Hz. For both of these countries the range selector must be set to 115V. Countries in the EEC
have standardized at 230 V / 50 Hz, however, there are different types of AC plugs used. For all the EEC countries
the selector should be in the 230V position. When using plug adapters or operating in a territory other than the one
in which the unit was purchased, take great care to comply with local safety requirements and electrical codes of
practice.
If you are not sure of the local voltage, wiring codes & colors, AC grounding, or correct procedures for
connection, consult a qualified technician.
Warning
Under no circumstances should the ground pin on the PPA-300 or on any of your electrical equipment
be removed (cut off or disconnected). By following the correct procedures and safety precautions, risks
of severe shock hazard can be minimized. Avoid operating the system in conjunction with ungrounded or
improperly grounded electrical equipment.
TRANSPORTATION LATCHES
To open and close your PPA-300 system, simply follow these guidelines:
I.
Place your finger tip under the safety latch and gently lift. When the safety latch has disengaged, lift the main
latch to remove the speaker.
2.
To replace, position the speaker on the tower foot and bring the speaker in to close the engagement with
the tower and latch. Position the latch hook over the speaker notch and close the latch. The safety latch will
automatically engage.
Note: These parts are precision engineered and no force is needed to secure them. Careful alignment of parts will
ensure easy operation.
