Can I travel with the S8 Series II?

Your S8 Series II has an internal power supply that enables it to operate in other

countries. It will operate on power supplies of 100–240V and 50/60Hz. No special

adjustment is necessary, but you will require an approved power cord for the

region in which you are using the device.

Please consult the medical services department of your carrier if you intend to

use your S8 Series II on an aircraft. The S8 Series II complies with US FCC Part

15, Class B requirements.

Note: Do not use your S8 Series II while the aircraft is taking off or landing.

Can I use my S8 Series II if mains (AC) power is not available?

A DC-12 converter is available to connect the S8 Series II to a 12V or 24V DC

power source. Contact your clinician for details.

CAUTION

The device should not be connected to both AC and DC power sources

simultaneously.
