Turn on the laser
Status LED
Status LED flashes during self-leveling once a second.
When leveled, the status LED lights solid for the first five minutes or 30 seconds
(depending on settings), then flashes every four seconds indicating the laser remains
leveled and HI-alert has been activated.
If a grade value has been dialed in, the laser starts the temperature reference check while
the thermometer symbols are flashing.
After the temperature reference check the standard display appears and the A symbol
flashes until self-leveling has been completed.
Pressing and holding the E button shows the current rotation speed, the internal product
temperature and battery status.
