- Service by authorized personnel only.
Transportation Lock:
Before initial use, rotate the pointer on the underside transportation lock to the unlocked position (Figure 1).
Location:
- Use on a firm, steady surface.
- Avoid locations with excessive air current, vibrations, heat sources, or rapid temperature changes.
- Adjust leveling feet until the level bubble is centered (Figure 2).
Connecting Power:
- Battery: Remove the battery cover and install four C batteries according to polarity indications (Figure 3).
- AC Adapter: Connect the AC adapter plug to the input jack (Figure 3) and then to the AC supply. The AC adapter powers the balance when battery power is not needed.
