While in transit, your cabinet is  subjected  to more jarring and 
vibration  than  at  any  other  time,  and  the  display  may  require 
some  adjustment  at  start-up.  Refrigerators  are  designed  to 
maintain  38°  to  40°F  (3.3°  to  4.4°C)  and  Freezers  -2°  to  0°F 
(-19°  to  -18°C).  During  periods  of  heavy  use,  when  doors 
are  opened  repeatedly  or  remain  open  for  extended  period, 
or  if  warm  product  is  loaded  in  the  cabinet,  the  temperature 
displayed may  temporarily exceed  the “normal”  range. This  is 
common, as  warm air outside  the cabinet  mixes with cold  air 
inside.  If  your  thermometer  continues  to  display  temperature 
above  “normal”  range,  close  the  doors,  make  sure  they  seal 
tight  and  keep  them  closed  for  at  least  30  minutes.  If  a  high 
temperature is still displayed, check  the  thermometer by plac-
ing  a  pre-calibrated  temperature  sensing  device  in  the  center 
of the refrigerated compartment and keep the doors closed for 
at least 15 minutes. The thermometer should display the same 
temperature  as  the  sensing  device,  within  +/-2°F  (+/-1°C).  If 
it  does  not,  follow  instructions  below  for  calibration  mode  to 
adjust the offset.
ADJUSTING PROGRAM SETTINGS
Press ‘SET’ on front to display settings in this order:
HSP
-40 to 199
= High Alarm Set Point
= High Set Point value*
LSP
-40 to 199
= Low Alarm Set Point
= Low Set Point value*
HI
-40 to 199
= High temperature log
= Highest temperature recorded since reset last 
pressed (Press Reset to clear value)
LO
-40 to 199
= Low temperature log
=  Lowest  temperature  recorded  since  Reset  last 
pressed (Press Reset to clear value.)
CAL
= Calibration Mode
-30 to 30 = Calibration temperature display offset value*
Calibration example: If sensing device in cabinet reads 38° and thermometer 
displays 41°, press ‘SET’ 10 times, to display temperature offset value. Then 
press down arrow three times, to decrease offset by 3°. (If original offset value 
displayed was “0”, then “-3” will appear).
*To adjust value, press up or down arrow until desired setting is 
displayed. Then press ‘SET’ to save.
IMPORTANT: If sequence is interrupted for more than 15 
seconds, or not completed to where the display flashes 
once, unit  will  automatically  revert  back  to  temperature 
mode, WITHOUT saving new values (tamper resistant).
