General warnings and cautions
WARNING Patient or operator injury risk. Maintain control of the patient at
all times, including when the patient is stepping on and off the scale.
Failure to do so could result in a fall risk or other serious injury to you or the
patient.
WARNING Patient or operator injury risk. Make sure the scale is
positioned on a stable surface and in a way to avoid shock or bumping
hazards.
WARNING Patient injury risk. Make sure the scale is set in the proper
measurement units for your facility. Make sure you record the
measurement units as they are displayed.

Introduction Welch Allyn Masted Scales
WARNING Electric shock hazard. Use only a Welch-Allyn approved power
supply. The use of an unapproved power supply could increase chassis or
patient leakage currents.
WARNING Electric shock hazard. Use only a Welch-Allyn approved power
supply. The use of an unapproved power supply could cause electric harm
and shock to you or the patient.
WARNING Electric shock hazard. All signal input and output (I/O)
connectors are intended for connection of only devices complying with IEC
60601-1, or other IEC standards (for example, IEC 60950), as applicable to
the scale. Connecting additional devices to the scale could increase chassis
or patient leakage currents. To maintain operator and patient safety,
consider the requirements of IEC 60601-1-1. Measure the leakage currents
to confirm that no electric shock hazard exists.
WARNING Electric shock hazard. Make sure that the USB (SIP/SOP) port
and the patient are never touched or come in contact at the same time.
WARNING Patient or operator injury risk. No modification of this
equipment is allowed.
CAUTION Make sure that you routinely perform general maintenance and
equipment safety checks on your scale. Remove the scale from service
when you notice damaged power cable.
CAUTION Do not use this scale to transport patients or items.
CAUTION The scale may power down due to electrostatic discharge.
There is no risk associated with this action. Turn the scale on and it will
function normally.
