CARE OF YOUR STOPWATCH
WATER RESISTANCE
- The stopwatch is designed to withstand accidental contact with water such as splashes or rain,
but it is not designed for use in water. Do not operate the buttons when the stopwatch is wet.
TEMPERATURE
- Do not leave your stopwatch under direct sunlight or in very high temperatures for a long time,
the display may become black. Do not leave your stopwatch in very low temperature as this may
cause a slight time loss or gain and the change of digits becomes slow. In both cases the above
conditions will be corrected when the stopwatch returns to normal temperature.
