• Monitor cutaneous responses of patients who are incapable
of reacting, communicating and/or who cannot sense
temperature a minimum of every 15 minutes or according to
institutional protocol.
• Adjust air temperature or discontinue therapy when the
therapeutic goal is reached, if elevated temperatures are
recorded or if there is an adverse cutaneous response in the
warmed area.
• Do not place the warming unit on a soft uneven surface,
such as a bed, or a visibly wet surface as the air intake may
become blocked and cause the warming unit to overheat,
compromising the warming unit's performance.
• Perform all temperature testing of the warming unit with a
3M Model 22110 temperature test unit.
!
CAUTION: To reduce the risk associated with
electromagnetic interference (EMI) due to portable and
mobile radio frequency (RF) communications equipment:
• The 3M Bair Hugger temperature management system has
been tested to be resistant to both EMI and electrostatic
discharge (ESD).
• Install and put into service the 3M Bair Hugger temperature
management system according to the electromagnetic
compatibility (EMC) information provided in the Guidance
and Manufacturer's Declaration.
• Should interference occur, move away from the portable or
mobile RF communications equipment.

Warming Unit Power‑On‑Reset
The Model 775 warming unit automatically performs the following
power-on-reset sequence after you connect the warming unit to a
properly grounded power source:
• Performs all self-test functions.
• Illuminates indicator lights and all pixels in the
alphanumeric display momentarily.
• Displays the text "MD 700's" and the software revision
level in the alphanumeric display.
• Sounds the alarm (three low-level clicks).
• Enters the Standby mode with the high fan setting selected
by default.
Note: The low fan setting indicator light will not illuminate
during power up.
If the warming unit loses power for less than 1 second, the warming
unit software will return the warming unit to the operating mode
you selected prior to the power loss. However, if the warming unit
loses power for longer than 1 second, the warming unit software will
reset when you restore power. The warming unit will then enter the
Standby mode with the high fan setting selected by default.
