CONTROL PANEL OVERVIEW 

 

4.1 

Power Switch: 

The main power I/O (on/off) switch controls all power to the unit 

and must be in the I or ON position before any systems are operational. 

4.2 

Temperature Controller: 

The controller is marked SET TEMPERATURE and is 

equipped with an adjustment  knob and a graduated  dial.  The graduated dial is 
marked  with  10  major  increments  and  50  minor  increments.    These  increments 
can be used as index points for setting and returning to set point temperatures. 

4.3 

Heating  Lamp:

  This  green  pilot  lamp  is  marked  HEATING  ACTIVATED.    It 

indicates  when  the  element  has  been  activated  and  the  incubator  is  heating.  
When  set  point  is  reached  the  pilot  light  will  cycle  on  and  off  as  the  elements 
maintain set point. 

4.4 

Circuit Breaker / Fuse:

 This control is adjacent to the power cord and provides 

protection for the unit

’s electrical circuitry against power fluctuations.  The circuit 

breaker,  when tripped,  must  be  reset  by  pushing  in  the extended button for  the 
unit  to  continue  operation.    The  fuse,  when  blown  (on  CE  units  in  place  of  the 
circuit breaker) must be replaced before the unit can continue operation.
