Sleep Mode
Pressing the power key on the remote control will make the
instrument enter or exit the Sleep mode. When the instrument is
in Sleep mode, the LCD is shown as the following figure.
When the instrument is in Sleep mode, except for the power key, all
the other keys are disabled.
Note:
In the Sleep mode, the instrument will keep the current setting value.
When the instrument is turned on, it will be in the same setting as
before entering Sleep mode.
All other remote key pad functions operate the same as the keypad
functions on the laser.
Beyond-tolerance Alarm
The auto-leveling range of the instrument is ±5°.
When the instrument is auto-leveling, if the instrument is
tilted to exceed the auto-leveling range, it will give a
sound alarm, simultaneously the sign “LEV” on the LCD
will blink, as shown in the figure.
While the sign “LEV” is blinking, if the “X” sign is flashing, it means
the X-direction exceeds the auto-leveling range. If the “Y” sign is
flashing it means the Y-direction exceeds the auto-leveling range.
If the “X” and “Y” signs are flashing, it means the X-axis and Y-
axis both exceed the auto-leveling range.
