Use the four numbers on the back of your watch and you will have a PDF version of your instruction manual.

Hope this tip helps.

open the backside.
probably the light switch contact at the six side of the watch (attached to the steel mainframe) may have contact with the electronic cirquit

hi lagathon121 I had the same problem after i replaced the battery and what i did was to short the + end of the battery plate with the - end for two seconds, apparently this will reset the watch. there is also a sticker pasted on the battery plate holder.

I like these little RC IR watches. They're great fun!!! For this tutorial, you will need....

• A small Phillips heads screw driver
• A pin (or needle)
• A replacement CR2032 battery

1. Remove the 4 screws from the back of the watch
2. Carefully remove the back plate, do not damage the delicate rubber seal
3. Carefully remove the delicate rubber seal
4. Use the pin to remove the small rubber block from the battery cover clasp.
5. The pin should then be inserted in the gap of the white plastic lug, where the rubber block was removed.
6. Use the pin to gently pull back the clasp of the battery cover.
7. The battery cover will then open with a 5mm gap approx. It does not need to be removed.
   
8. Use the screwdriver to remove the battery.
9. After the battery has been replaced, just follow the instructions backwards.
