RefSmart Universal Game Day Timer Instructions

Feb 28th, 2024

The RefSmart Universal Timer can be used by football officials, baseball & softball umpires and lacrosse referees. See the instructions below to set your timer to the correct time settings. Note: if purchased from Ump Attire, the default time setting for your timer will be 20/90. After the switches have been changed, turn the timer off and back on to calibrate & finalize the new setting.

changing timer mode

  • Remove the lid with a flat head screw driver. There are three indentations along the seam of the timer. You should use a flathead screwdriver to pop the cover.
  • Inside you will see the small DIP switches just above the power switch (see image below)
  • To move the switches use a pen, paperclip or small flathead screw driver.
  • Switch 1 controls audible/silent. To the left (towards batteries) is vibrate only, to the right (towards toggle) is audible tone and vibrate.

  • Use the following configurations (note: switch 1 is closest to the bottom)
    • 25/40 (silent): Switch 2 to the right, all others to the left
    • 25/40 (audible): Switch 1 & 2 to the right, 3 & 4 to the left
    • 25/60 (silent): All switches to the left
    • 25/60 (audible): Switch 1 to the right, all others to the left
    • 20/90 (silent): Switch 1 to the left, all others to the right
    • 20/90 (audible): All switches to the right 
    • 20/120 (silent): Switches 2 & 3 to the right, all others to the left

  • Thank you for posting these instructions on the website! Also of note: When you change the internal DIP switches to reprogram the timer, it will not change modes until you flip the main (exterior) power switch "off," then back "on." The easiest way to say it is: Change the DIP switches with the main (exterior) power switch "off," then turn the unit back "on" to test your new settings. Hopefully this advice saves someone in the officiating brotherhood a little trouble! I sat and flipped switches for 10 minutes with the main power "on" wondering why nothing was happening. As my frustration mounted, I finally figured out that the unit must be turned "off" to change settings.

  • Can the old model (purchased in 2015) be modified to vibrate at 25 seconds remaining on the 40 sec. clock?

    • I'm sorry Jacob but the feature to vibrate at 25 seconds remaining on the 40 second clock is new and only available on timers purchased after the summer of 2019. You are able to change the mode on your old timer (using the instructions above).
