1)
To avoid the possibility of electrical shock, DO NOT use this apparatus near water.
WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or direct moisture.
2)
Clean only with dry cloth.
3)
DO NOT block any ventilation openings. Install in accordance with the manufacturer’s instructions.
4) DO NOT allow foreign objects to pass through the grill face or touch the emitter
5)
DO NOT install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
6)
DO NOT defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades
with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult
an electrician for replacement of the obsolete outlet.
7)
Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and
the point where they exit from the apparatus.
8)
Only use attachments/accessories specified by the manufacturer.
9)
Unplug this apparatus during lightning storms or when unused for long periods of time.
10) Refer all servicing to qualified service personnel. Servicing is required 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.
11) Use 3-inch minimum spacing distances around the apparatus for sufficient ventilation.
12) The ventilation should not be impeded by covering the ventilation openings with items such as
newspapers, table-cloths, curtains, etc.
13) No naked flame sources, such as lighted candles, should be placed on or near the apparatus.
14) Due to the potential of extreme temperatures, do not place this unit in direct sunlight for extended
periods of time.
15) While medical research indicates that the levels of ultrasound used in this HSS device do not cause any harm
to human hearing, tissue, or body parts, common sense would dictate and ATC recommends that you follow
prudent safety procedures as you would with any loudspeaker device operating over 80-90 dB SPL.
16) It is recommended that when operating the HSS emitter in “direct” mode (pointed directly towards
the intended listener), that you maintain a > 1m (3 ft) distance between the emitter surface and the listener.
17) This product is approved for Indoor use only.
18) It is recommended that you at no time aim the emitter directly into the ear canal at less than 1m (3ft) distance.
19) DO NOT store, ship or use where temperature may go below 14
