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
