1.2 Precautions

This product has been designed with your safety
in mind, but please pay attention to the following
warnings and cautions before use.

Warnings
In order to avoid the danger of electrical shock, it
is important that proper safety measures are taken
when working with voltages exceeding 30V AC
rms, 42V AC peak or 60V DC.

Where applicable other safety measures such as
the use of protective gloves, goggles etc. should be
employed.

The magnetic field detector must only be used by
a skilled and competent person who is familiar with
the relevant regulations, the safety risks involved
and the consequent normal safe working practices,
and under the conditions and for the purposes for
which it has been constructed and specified.

Before each use the magnetic field detector should
be examined for damage, cracks, cuts or scratches.
Do not use if damaged in any way.

Make sure the magnetic field detector is dry, clean
and free from dust, grease and moisture while in
use to avoid the danger from electric shock due to
surface leakage.

Do not use if the battery compartment end cap is
not fitted.

Always keep your fingers behind the finger guard.

Do not use the magnetic field detector during rain

or precipitation.

The magnetic field detector will not detect voltage.
