The rotary head speed can be set to 300,600 or 900

Height Alert function
This is an optional setting that must be activated by the user. When active, the Height Alert
function will not allow the RT-5SW to continue operating if the unit is disturbed after it has auto-
leveled. This reminds the user that to insure accurate control, the height of the beam should re-
checked after the unit has been disturbed.
If the function is active and the unit is disturbed, the red LED visible when the RC-300W is
removed will blink rapidly. To re-activate auto-leveling, turn the power key OFF and ON again.
After auto-leveling is complete check the beam elevation using the LS-70A to confirm it has not
changed.
If the Alarm Signal [COM] function is also active when the Height Alert function is active,
the rotary head will continue to rotate to communicate the alert to the LS-70A laser
sensor.
