OPERATION
Remove the laser from its carrying case. The instrument is shipped with a battery current
protection insert, which must be removed before operation.
NOTE: All ALH and ALHV(-G) instruments are shipped with ADS on as the default setting. This
setting can be changed by the user (see Anti-Drift System - ADS, page 16).
NOTE: ALGR instruments will default to Grade Mode when the instrument is turned on. The Mode
button is used for both selecting between the X-axis and Y-axis for setting grade and exiting
the Grade Mode (see Grade Mode — Dual or Single Axis Grade). Press and release the
Mode button to select between the X-axis and Y-axis when setting grade. To exit the Grade
Mode, press and hold the Mode button for 4 to 5 seconds, then release. This will bring up
the Mode Select Menu. The user can now toggle to other menu options. Pressing the Mode
button for 4 to 5 seconds and releasing is only required to exit the Grade Mode.
