4.4.1 Electromagnetic compatibility
Although the range meter complies with the strict require-
ments of the relevant guidelines, Hilti cannot entirely rule
out the following possibilities:
• The range meter might cause interference to other equip-
ment, e.g. aircraft navigational equipment.
• The range meter might be subject to interference caused
by powerful radiation, which can then lead to incorrect
operation. Check the readings for plausibility when mea-
suring in these conditions or if you are unsure of the results.

4.4.2 Laser classification

The range meter conforms to laser class 2 based on the
IEC825-1 / EN60825-1 standard and class II based on CFR
21 § 1040 (FDA). These range meters may be used without
need for further protective measures. The eyelid closure
reflex protects the eyes if a person looks into the beam unin-
tentionally for a brief moment. The eyelid closure reflex can,
however, be negatively influenced by medication, alcohol or
drugs. Nevertheless, as with the sun, a person should not
look directly into sources of bright light. The laser beam
should not be directed towards persons.

5.1 Inserting alkaline / rechargeable batteries

-CAUTION-
• Observe the polarity of the batteries. (refer to signs inside
the battery compartment.)
• Make sure the battery compartment is properly shut.
1. Unscrew the battery compartment with the key provided
2. Insert the batteries.
3. Screw battery compartment cover back, making sure
thread is engaged to ensure complete closure to main-
tain dust and water protection.

5.2 Switching the range meter on and off

The range meter is switched on or off by pressing the "On /
Off" key.
After being switched on, the range meter is in the basic dis-
play mode.

5.2.1 Initial distance measurement

Press the "Measure" key once.
This will switch on the range meter and the laser beam if the
range meter was switched off.
If the range meter is already switched on, this will activate
the laser beam.
