3. Inserting batteries
Remove the battery cover (5) and insert
3 x AA/LR6 batteries (sold separa-
tely) observing the polarity markings in
the compartment. Refit the battery cover
and ensure it sits securely.
Warning! Always switch the laser off
before changing batteries.
• Change batteries when either of
the indicator lights, (8) or (9) begin
flashing red on the control panel.
• Never mix old and new batteries or
batteries of different types.
• Remove any discharged batteries
immediately.
4. Operating instructions
1. Place the laser level on a firm horizontal surface or screw it onto the tripod.
2. Set the [ ON/OFF ] switch (1) to the
ON position. Select the desired setting
by pressing [ MODE ]:
There are four modes to select from:
- A. Normal cross-line self-levelling mode is the default function when first turned
on: Cross-line laser (unlocked with self-levelling and incline warning activated).
- B. Press [ MODE ] once to switch to a horizontal mode.
- C. Press [ MODE ] twice to switch to a vertical mode.
- D. Press [ MODE ] a third time for cross-line locked mode (incline warning
deactivated). Depending on what is selected, indoor or outdoor mode, one of
these indicator lights, (8) or (9) will show a steady red to indicate cross-line locked
mode. Press [ MODE ] once again to return to normal cross-line laser mode.
3. In normal cross-line laser mode the self-levelling feature will automatically
compensate for a small margin of incline error (within 4°). The laser beam is ready
to be referenced once the beam is solid and still.
Note! If the instrument is inclined
more than 4° from the horizontal, the self-levelling feature will not work.
Angles exceeding 4° will cause the indicator lights, (8) or (9) to show a steady red
and the laser beam to flash. The angle must be within 4˚ of horizontal for the self-
levelling feature to work.
