• How do I unlock the screen on my SINOTIMER digital timer?

  Most SINOTIMER models (like the TM928) have a screen lock function. Press and hold the 'MENU' or 'C/R' button (depending on the model) for about 3 to 5 seconds until the lock icon disappears from the display.

• How do I reset my SINOTIMER device to factory settings?

  Press the small 'Reset' or 'Res' button with a pointed object. This will clear all programmed settings and the clock, returning the device to its default state.

• How do I set the over-voltage protection limit?

  On SVP series protectors, press the 'SET' button to enter the parameters menu. Use the up/down arrows to adjust the over-voltage threshold value, then long-press 'SET' to save and exit.
