• The operating range may be affected by environmental factors and nearby
sources of interference.
• Proper use helps to prolong the lifespan of the product.
b) Batteries
• Correct polarity must be observed while inserting the battery.
• The battery should be removed from the device if it is not used for a long period of
time to avoid damage through leaking. Leaking or damaged batteries may cause
acid burns when in contact with skin, therefore use suitable protective gloves to
handle damaged batteries.
• Batteries must be kept out of reach of children. Do not leave batteries lying
around, as there is a risk that children or pets may swallow them.

time, slowest and fastest average time, and 10-lap memory information.
• The countdown timer can be set to start at any time in the measurement range (between 9
hours, 59 minutes and 59.99 seconds and 0.01 seconds) and then countdown to 0 seconds.
• The metronome tempos include 10, 20, 30, 40, 60, 80, 100, 120, 180, 240 and 320 beats
per minute.

Operation
When turning on the stopwatch, the time is initially displayed. Press the S4 (Mode) key to toggle
between the following modes:
1. Clock
• The upper row of information displays the week, month, day and year, while the lower row
displays A (for AM) or P (for PM) if in 12-hour time format and the time in hours, minutes
and seconds.
• To adjust the year, month, day, 12/24-hour time format or time, press the S3 key to toggle to
the desired item. Then press the S1 key to adjust the value and press the S3 key to confirm
the change. Note that the first row displays the week number in Arabic numerals, which is
automatically adjusted based on the date and so cannot be adjusted directly.
2. Stopwatch
• Press the S1 key to start the stopwatch timer. The displayed upper value is initially zero and
the lower value is the timer. Press the S1 key to stop the timer (displaying STOP on the
screen) and then press the S1 key again to re-commence the timer. Press the S1 to stop
the time first, and then press the S3 key to return the time to zero.
•
While timing, press and hold the S3 key to display the first recorded time on the upper row
and the total time on the lower row. Then release the S3 key to continue displaying the first
recorded time on the upper row and the continuing timer on the lower row. This process can
be repeated for each recorded time for up to the maximum time range (9 hours, 59 minutes
and 59.99 seconds).
