Check the combination, as well as the machine
Compare your power supply’s connection and voltage range with these specifications. A matching plug alone does not confirm that every part of the setup is suitable together. Also check the cable, chosen needle or cartridge configuration and the manufacturer’s instructions.
Stroke length and needle protrusion are different settings. Use the 1–5 mm range as a specification for comparison, rather than an automatic treatment recommendation. Appropriate use depends on your training, the particular configuration and the operating instructions.
The product page does not list a complete starter kit with all consumables. Check what is supplied and what you already own. This helps avoid ordering a machine while an essential part of the setup is still missing.
Three questions before ordering
- Does the RCA connection match my cable and suitable power supply?
- Does the manufacturer explicitly support my chosen configuration?
- Which components and consumables must I select separately?
