Rechargeable Batteries
Rechargeable lead-acid batteries are the same type used in automobiles. As with your car
battery, how you use this battery has a significant impact on its lifespan. With proper use and
treatment, a lead-acid battery can last for years. Here are some recommendations for getting
the longest life from the internal battery.
General
Usage
Fully charge the battery before using the loudspeaker.
Charge the battery completely after each use.
Storage
For best product longevity, do not store at exceedingly hot (greater than
90 °F / 32 °C) or exceedingly cold (less than 32 °F / 0 °C) temperatures.
It is acceptable to leave your loudspeaker plugged in. This will not overcharge
the battery.
If you leave the battery level low and do not charge it for 6 months, the
battery may permanently lose capacity.
Repair
If the battery fails to charge, contact Alto Professional at
.
Disposal
Bring the unit to a recycling center or dispose of in accordance with local
ordinances.
Stand-Mounting
Presenter PA features a 1-3/8" (3.5 cm) diameter pole socket for mounting on a stand. We
recommend using a stand that is adjustable between 30–36" (76–91 cm) in height for best
results. When using a stand with Presenter PA, make sure to follow these guidelines:
•
Always install loudspeakers in accordance with applicable electrical and building codes.
•
Install the loudspeaker according to its maximum weight. Check the specifications of your
stand or pole to ensure it can support the loudspeaker’s weight. Also, observe all safety
precautions specified by the manufacturer.
•
Do
not
mount multiple loudspeakers on the same stand or pole.
•
Always verify that the stand or pole is on a flat, level, and stable surface. Also, fully extend
the legs of tripod-style stands, and ensure its legs do not present a trip hazard.
•
Inspect the stand (or pole and associated hardware) before each use and do not use
equipment with worn, damaged, or missing parts.
•
Always be cautious in windy, outdoor conditions. You may need to place additional weight
(e.g., sandbags) on stand’s base to improve stability. Do not attach banners or similar
items to any part of a loudspeaker system. Such attachments could act as a sail and
topple the system.
•
Unless you are confident that you can handle the loudspeaker’s weight, ask another
person to help you lift it onto the stand or pole.
•
Make sure your cables are out of the way of performers, production crew, and audience so
they will not trip over them, pulling the loudspeaker off the stand or pole.
