2. After going to the calibration menu in diagnostics, hold the zero and lb / kg buttons for two seconds to
zero the stretcher. The display will read Hold. Release the button when the display reads Rel. The
display will read 000.0 then 200.0 lbs.
3. Place a calibrated 200 pounds on the middle of the stretcher litter.
4. Hold the zero and lb / kg buttons for approximately two seconds. The display will read Hold. Release
the button when the display reads Rel. The scale system is calibrated. To check the calibration, place
several known weights on the litter and verify the scale displays the correct weight reading.

is pressed. To lock the weight unit, hold the zero and lb / kg button for two seconds. After going to the unit
