1: First turn clockwise 0-55 to 55 scale, then tighten the clockwork. (Exceeding the scale will reverse and damage the gear. When the scale is at 0, you cannot directly rotate counterclockwise in the direction of 55).2: Return to the required timing scale again (for example, when the timing is 5 minutes, return to scale 5).3: Place it and wait for the bell to remind you4: Remember The clockwork must be wound first every time, if it is directly screwed to the timing time, it will not sound.Due to the gap in the operation of the gear structure, the error of the ringing time is about 1 minute, please be awareColor: as picture Material:Plastic Item NO: 792452-792461,792408 Size:panda/frog--Diameter * height 7*7cm vegetables--diameter 6.5cm ,height 4cm Conversion: 1inch=2.54cm, 1cm=0.393inches Warm Tip : Please be reminded that due lighting effects, monitor's brightness/contrast settings etc, there could be some slight differences in the colour tone of the website's photo and the actual item.
