  • Page 13: Preparation For Use

    Preparation for Use Power Source Connect the battery according to the type of battery purchased. For handling batteries, see the "Handling Power Sources" chapter. Setting Instrument Up Set the instrument on a tripod or smooth surface. Power Key Turn the instrument ON or OFF by pressing the power key. Automatic leveling will start by turning the power switch ON.

  • Page 14: Auto-Leveling Lamp

    Auto-leveling Lamp Blinking : Leveling automatically. When automatic leveling is almost complete, blinking will slow. The rotary head is rotating slowly, and the laser beam is emitting. On solid : Completes leveling. The rotary head is rotating (600rpm) and emits a laser beam horizontally.
