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

separating iso-transformer. (The additional equipment may increase the current
amount of leakage and exceed the safety limit.)

types of interference. This may cause the Welch Allyn OAE Hearing Screener
equipment to function incorrectly.
