1. Remove the battery compartment cover on the back of the rotary timer.
2. Insert an AAA/micro battery into the battery compartment of the rotary timer in the 

correct position (observe the plus/+ and minus/- signs).

3. Put the cover back on the battery compartment.

We recommend that you use high-quality alkaline batteries in order to 

ensure prolonged and safe use. In principle, the rotary timer can be 

operated with rechargeable batteries. However, as rechargeable batteries have a 

lower voltage (rechargeable batteries = 1.2 V, non-rechargeable batteries = 1.5 V) and

capacity, the battery life will be shorter compared to non-rechargeable batteries. If 

you still wish to use rechargeable batteries in spite of these limitations, be sure to use 

special NiMH rechargeable batteries with a low self-discharge.

•  Using the magnet, secure the timer to a magnetic, metal surface (vertical/horizontal).
•  Pull lightly using your finger to open the stand on the back of the clip. Pull it carefully

until  you  hear  the  stand  click  into  place.  Now  you  can  put  the  timer  on  any  flat

surface.

•  Of course, you can also hold the timer firmly in your hand.

•  Press the START/STOP button (1) to start timing. The rotary timer counts upwards 

from zero.

displayed digitally on the display.

•  Press the START/STOP button again to resume timing from the stopped position.

•  Turn the adjustment dial (3) to preset the countdown time. Decrease the countdown 

time by turning the adjustment dial anticlockwise. The minus/- direction is shown
