7.8 Returning to standard mode
To return to standard operating mode, switch the tool off
and then switch it back on again.
7.9 Sleep mode
The PR 30-HVS can save power when in sleep mode.
The laser is switched off, thereby extending battery life.

7.9.1 Activating sleep mode
1.
When the PRA 30 is switched off, press and hold the
on/off button of the PRA 30 for approx. 3 seconds.
8 Care and maintenance
8.1 Cleaning and drying
1.
Blow dust off exit windows.
2.
Do not touch the glass with the fingers.
3.
Use only a clean, soft cloth for cleaning. If necessary,
moisten the cloth slightly with pure alcohol or a little
water.
NOTE Abrasive cleaning materials may scratch the
glass and impair the accuracy of the laser tool.
NOTE Do not use any other liquids as these may
damage the plastic components.
4.
Dry the equipment, observing the maximum tem-
peratures given in the technical data.
NOTE Especially in summer and winter, take care
that the given maximum and minimum temperatures
are not exceeded, e.g. when the equipment is stored
in a motor vehicle.
8.2 Care of the Li-ion battery
NOTE
A conditioning charge (as is required with NiCd or NiMH
batteries) is not necessary with Li-ion batteries.
NOTE
Interruption of the charging procedure has no negative
effect on battery life.
NOTE
Charging can be started at any time with no negative
effect on battery life. There is no memory effect (as with
NiCd or NiMH batteries).
NOTE
For best results, batteries should be stored fully charged
in a cool dry place. Storing the battery in places subject
to high ambient temperatures (e.g. at a window) has an
adverse effect on battery life and increases the rate of
self-discharge.
NOTE
Batteries lose capacity due to aging and overstressing.
They can then no longer be fully charged. You may
continue to work with a battery that shows signs of
aging, but the battery should be replaced in good time.

2.
Press the "Right" arrow button twice to access
"Sleep mode" in the menu.
3.
Press the "Units" button to activate the sleep mode
on the PR 30-HVS.
7.9.2 Deactivating sleep mode
1.
When the PRA 30 is switched off, press and hold the
on/off button of the PRA 30 for approx. 3 seconds.
2.
Press the "Right" arrow button twice to access
"Sleep mode" in the menu.
3.
Press the "Units" button to deactivate the sleep
mode on the PR 30-HVS.
4.
To ensure working accuracy, check the laser set-
tings after the PR 30-HVS has been reactivated.
1.
Avoid ingress of moisture.
2.
Charge the battery fully before using it for the first
time.
3.
Charge the battery as soon as its performance be-
gins to drop significantly.
NOTE Recharging in good time will increase the
service life of the battery.
NOTE If use of the tool continues, further battery
discharge will be stopped automatically before the
battery cells suffer damage.
4.
Charge the battery with the Hilti charger approved
for use with Li-ion batteries.
8.3 Storage
1.
Remove the appliance from its case if it has be-
come wet. Dry and clean the tool, its transport
container and accessories (while observing the per-
missible temperature range). Repack the equipment
only once it is completely dry.
2.
Check the accuracy of the equipment before it is
used after a long period of storage or transportation.
3.
Remove rechargeable and non-rechargeable batter-
ies from the tool or the laser receiver before storing
the units for long periods. The tool or laser re-
ceiver may suffer damage caused by leakage from
rechargeable or non-rechargeable batteries.
8.4 Transport
Use the Hilti toolbox or packaging of equivalent quality
for transporting or shipping your equipment.
CAUTION
Remove the batteries from the tool and receiver before
transport or shipping.
8.5 Calibration by the Hilti Calibration Service
We recommend that the tool is checked by the Hilti Cal-
ibration Service at regular intervals in order to verify its
reliability in accordance with standards and legal require-
ments.
Use can be made of the Hilti Calibration Service at any
time, We recommend that the tool is calibrated at least
once a year
