Use a clean, dry and soft cloth for cleaning. If the device is very dirty, use a cloth slightly mois-

tened with lukewarm tap water.
Clean the product very carefully; otherwise you may scratch it.
Do not press too heavily on the glass cover, as this can lead to breakage.

   Do not use abrasive cleaning agents, cleaning alcohol or other chemical solutions, 

since these could damage the casing or even impair operation. 

   Electronic devices are recyclable material and must not be disposed of in the house-

hold waste!

 

 Please dispose of the product, when it is no longer of use, according to the current 

statutory requirements.

 

 Remove any inserted battery and dispose of it separately from the product.

As the end user, you are required by law (Battery Regulation) to return used batteries and 

rechargeable batteries. Do not dispose of used batteries in the household waste!

   Batteries/rechargeable  batteries  contain  harmful  materials  and  are  labelled  with 

the symbol shown to indicate that disposal in the household waste is forbidden. 

The symbols of the critical heavy metals are: Cd=cadmium, Hg=mercury, Pb=lead 

(marking  can  be  seen  on  the  battery/rechargeable  battery,  e.g.,  underneath  the 

refuse bin symbol shown on the left).

You can return your used batteries/rechargeable batteries free of charge at the official col-

lection points in your community, in our stores, or at places where batteries or rechargeable 

batteries are sold!
That way you are fulfilling your statutory obligations and you are contributing to the protection

•  The operation is the same for both modes. Therefore, we describe below the operation and 

use of the lap time “LP00” only.

•  To start the timer, press the key S2. “LP00” is shown in the top of the display.
•  To time the first lap, press the key S3 while the stopwatch is running. That way the current 

time will be saved as “LP01”. “LP01” is also indicated at the top of the display. Now press the 

S1 button to change back to the current display. Then time the second lap. The latter will be 

saved as “LP02”. “LP02” is also indicated on the display.

•  You can repeat these steps, until “LP09” is shown on the display, in other words, when you 

have saved the ninth lap time as “LP09”.

•  When you get to the tenth and last lap time, i.e. “LP09” already appears at the top of the dis-

play, you have to press the S2 key. This will save the last lap time “LP10” and simultaneously 

complete the timing.

  While the lap time is displayed, the stopwatch continues to run in the background.
•  To stop the timing of each time, press the key S2.
•  Press the S3key twice to reset the display to zero and thus delete all stored values. Of course, 

prior to that, you have to evaluate the timings under the menu point “CALL” (next chapter).

•  After completed timing, press the S1 key once to switch to the evaluation function “CALL”. 

For this purpose, also see chapter “Functions”.

•  Here, you can toggle between the stored split and lap times using the S2 and S3 key.
  The last split time “SP” also represents the total time of the reading.
  The lap time “LP—” is the total time of all laps.

•  If the desired alarm function “A1” or “A2” is not displayed, press the S1 key until this function 

is shown. The setting for “A1” and “A2” is identical. For this purpose, also see chapter “Func-

tions”.

•  To set the time for the alarm, press the key S2. The hour display will start to flash.
•  You can now also toggle between the hours and minutes using the  S2 key. While the minute 

display is flashing, you can press the S2 key again to exit the setting mode and to save the 

setting.

•  With the S3 key you can change the value of the selected setting.
•  With the S1 key you can exit the setting mode at any time. If no button is pressed for 1 minute, 

the setting mode shuts off automatically. The current setting will be saved anyway.

•  To enable or disable the alarm, press the S3 key while the alarm time is shown and no 

indication flashes. When the alarm is disabled, the displays shows “OFF”. When the alarm is 

enabled, the alarm time is displayed and the alarm icon is shown at the top left.

•  If the stopwatch beeps because of the alarm setting, you can stop the alarm using any of the 

three keys.

•  If the display does not show anything, the battery has to be replaced.

   If you do not have the expertise required to replace the battery, consult a specialist.

•  First remove the 6 screws on the back of the stopwatch. 
•  Then carefully remove the housing cover.
•  Now unscrew the single screw that is used to lock the battery holder (white round sticker).
•  Carefully remove the battery holder.
•  Replace the battery (CR2032). Make sure that the polarity is correct when inserting the new 

coin cell. When the stopwatch’s display faces downwards, the plus pole has to point upwards.

•  Put the battery holder back in place and fasten it. 

   If all segments of the stopwatch are displayed continuously after inserting the bat-

tery, perform a reset. To this end, bridge the two contact surfaces below the labelling 

“Reset” using a pair of metal tweezers or a paper clip. These contact surfaces are 

located on the right, next to the battery holder.

•  In a final step, attach the rear housing cover and tighten the 6 screws again.
•  Thereby the battery replacement is completed.
