Levelling lock
See also Levelling the instrument
Levelling unlocked
In the unlocked position the instrument auto-
matically levels itself within the specified inclin-
ation range. (See Technical data)
Levelling locked
Turn the levelling lock in order to transport or tilt
the instrument beyond the self-levelling range.
When locked, the pendulum is fixed and the self-
levelling function is deactivated. In this case the
laser blinks every 3sec.
Leica Lino L4P1 4
Instrument Set-up
Laser receiver
To be able to detect the laser lines over long dis-
tances
(>15 m) or in unfavourable lighting conditions, a
laser receiver can be used.
We recommend the Leica RVL80 laser
receiver.
Li-Ion battery
Charge Li-Ion battery
Charge the Li-Ion battery before using it for the
first time. While charging, the instrument may heat
up. This is normal and should not affect the instru-
ment´s lifespan or performance. At the recom-
mended storage temperature of -20°C to +30°C
(-4°F to +86°F), batteries containing a 50% to
100% charge can be stored up to 1 year. After this
storage period the batteries must be recharged.
CAUTION
Connecting the charger using the wrong adapter
may cause serious damage to the instrument. Any
damage caused by misuse is not covered by war-
ranty. Use only Leica-approved chargers, bat-
teries and cables. Unapproved chargers or cables
can cause the battery to explode or damage the
instrument.
Insert Li-Ion battery
Insert the battery-pack by pressing it down and
then tilting it towards the housing as shown until it
snaps in.
