Instruction Manual

– Optimal adjustment for turntables –
1. To insert the battery, please open the SPEED light with a thin screwdriver.
You can easily push it in and turn it, picture 1.
2.Take care about the polarity of the battery when changing (picture 2).
3. Please put the Stroboscope Testrecord on your turntable.
4. To adjust the optimal speed for the turntable with the SPEED light, hold the
Speed light about 1,97 – 3,94 inch (5 – 10 cm) over the Stroboscope
Testrecord (picture 1).
5. When the black lines stop in the blue light and do not move visible, you
have the optimal speed. (33 1/3 rpm outside stribe, 45 rpm inside stribe)
(picture 3)
- If the lines move around clockwise, the drive is too fast.
- When the lines clearly move anticlockwise, the drive is too slow.
6. For the optimal speed adjustment we recommend our Syncro (Art.Nr.
EL012), so you can exactly adjust the speed on the Hz.
5. If the intensity of the light reduces, please change the battery.
Use the exact battery type: V23GA – 12 V - Alkaline
- Attention -
The blue LED is not a laser diode!
Do not look directly in the light!
