in changing the strap on your Radiomir...
1. Use a good quality screwdriver, 1.4mm
2. Work on a good and steady surface, those very small screws can easily get lost. Try not to screw them all the way out .
3. Applying tape is not necessary if you work slowly with a steady hand.
4. Make sure you are aware that the wire lugs are inserted back in their correct position (that means with the little grove in the direction of the screws)
5. Do one side completely before you do the other.
Good luck!
