• Calibration is used to calibrate various system parameters.

• Configuration allows for custom setup of various options.

The chart below shows the selections under each of the modes.

Scroll for Parameters Arrows: Steps the operator through the parameters

of SET, CAL and CONFIG Modes. The right arrow goes to the next

parameter, the left arrow returns to the previous parameter.

Up Arrow: Increases or toggles the parameter values that have been select-

ed in the SET, CAL, and CONFIG Modes.

Enter: Must press Enter key to save to memory all changed values.

Down Arrow: Decreases or toggles the parameter values that have been

selected in the SET, CAL and CONFIG Modes.

Silence Key: Press to silence the audible alarm. See Section 4 for alarm

ringback times.

Units must be installed against a wall or similar structure. Maintain a three

inch clearance behind the incubator for electrical connections.

weight of approximately 500 lbs. Position it away from doors and windows

and heating and air conditioning ducts.

Warning This incubator weighs approximately 500 lbs. Have sufficient
