 Backlight
  Like the display, the LCD screen’s backlight also has power saving 
  options. The backlight can be either on continuously, off, or set   
  to automatically shut off after 30 seconds of inactivity. This option 
  can be changed by first pressing the F2 key to highlight the back 
  light parameter configuration tab. Once the tab is highlighted the 
  option can be changed by pressing the F2 key repeatedly or using 
  the UP and DOWN keys to select either “On”, “Off” or “Auto”.
  LED Modes
  The function of the two LEDs on the upper left corner of the 
  RTDTemp2000 can be regulated by first pressing the F3 key to   
  highlight the LED parameter configuration tab. Once the tab is 
  highlighted the option can be changed by pressing the F3 key 
  repeatedly or using the UP and DOWN keys to select either “Enabled”  
  meaning the LEDs will light to indicate device function or “Disabled”  
  meaning the LEDs will never light.
  5.5.ii.b Display Update Mode
  Selecting “MORE” by either pressing the F4 key or “OK” key while 
  viewing the Power Modes screen brings up the Display Update   
  Mode screen. On this screen, options relating to the refresh rate of 
  the screen are displayed. The F1 key toggles between ‘auto’ and 
  ‘reading’ modes. In ‘auto’ mode, the display is updated periodically, 
  whereas in ‘reading’ mode, the display only updates after a reading is 
  taken. F2 selects the update period option. Pressing the “UP” and 
  “DOWN” keys increase and decrease the update period respectively.
  5.5.ii.c Power Status
  Selecting “MORE” by either pressing the F4 key or the OK key while 
  viewing the Display Update Mode screen brings up the Power Status 
  screen. On this screen the battery type is displayed and should be 
  changed by the user based on whether a Lithium or Alkaline battery 
  is used in the RTDTemp2000. This can be changed by first pressing 
  the F1 button to highlight the type parameter configuration tab. 
  Once the tab is highlighted, the battery type can be changed by 
  either pressing the F1 key repeatedly or by using the UP and DOWN 
  arrows to select the correct battery type. The percent battery power 
  remaining, external power presence, battery voltage and external 
  power voltage are also displayed on the Power Status screen.
