Avoid moisture or contact with water, extreme atmospheric pressure, excessive
humidity and temperatures, poorly ventilated areas and dusty, saline or sulfuric air.
•
Verify the selected site maintains a relative humidity between 25% and 95%
(without condensation).
•
Verify all conditions meet the requirements listed in the Environmental
Specifications section of this manual.
Room Topography
Place all equipment on an even, level surface. Avoid the potential for mechanical shock
or possible vibrations during setup, system operation or when relocating the equipment.
System Hookups
• Verify the maximum load for any multiple portable socket-outlet (if used) does not
exceed 750 VA.
• Do NOT place any multiple portable socket-outlets (if used) on the floor.
• If multiple portable socket-outlets are used, DO NOT use the multiple socket-outlets
to power any equipment that isn't a part of the Welch Allyn OAE Hearing Screener.
(Adding other equipment may increase the current amount of leakage and exceed the
safety limit.)
• Do not interconnect multiple pieces of equipment without verifying that the sum of all
leakage currents does not exceed the safety limit.
• Do not connect any non-medical electrical equipment directly to a wall outlet if the
Welch Allyn OAE Hearing Screener is using a multiple, portable socket-outlet with a
separating iso-transformer. (The additional equipment may increase the current
amount of leakage and exceed the safety limit.)
• Do not connect equipment which can potentially provide electromagnetic or other
types of interference. This may cause the Welch Allyn OAE Hearing Screener
equipment to function incorrectly.
• Verify the equipment is connected to a power line source with the following frequency,
voltage and current capacity.
Frequency: 50 / 60 Hz
Voltage: 100 - 240 VAC
Current Capacity: 1.60 – 1.20A
