The HT50 uses a single inlet for both A.C. and D.C. power sources.
The inlet power connector automatically recognizes A.C. voltage
ranges from 100 to 240 and D.C. ranges from 12 to 30. A Newport
approved external battery can be attached to this connector.
WARNING To ensure proper grounding and prevent possible
shoc
k hazards, this device should only be connected to
“Hospital Grade” power receptacles.
WARNING HOME CAREGIVERS: External power in the
home en
vironment must support min. 100 to max. 240 VAC
and must have a grounded receptacle.

Power Cord Ferrite
Use of the Power Cord Ferrite ensures that the HT50 meets EMC
requirements. Anytime the HT50 is operating on A.C. power, the
ferrite should be attached to the power cord. Operating from D.C.
power does not require the use of the ferrite.
NOTE: Alwa
ys use the A.C. power cord supplied with the HT50.
