Safety Information
Do NOT service or repair this product unless properly qualified.
Servicing should be performed only by a qualified technician or an
authorized Audio Precision distributor.
Do NOT defeat the safety ground connection. This product is
designed to operate only from a 50/60 Hz AC power source (250 Vrms
maximum) with an approved three-conductor power cord and safety
grounding. Loss of the protective grounding connection can result in
electrical shock hazard from the accessible conductive surfaces of this
product.
For continued fire hazard protection, fuses should be replaced ONLY
with the exact value and type indicated on the rear panel of the
instrument and discussed on page 7-5 of this manual. The AC voltage
selector also must be set to the same voltage as the nominal power
source voltage (100, 120, 230, or 240 Vrms) with the appropriate
fuses. Different fuses are required depending on the line voltage.
The International Electrotechnical Commission (IEC 1010-1) requires
that measuring circuit terminals used for voltage or current
measurement be marked to indicate their Installation Category. The
Installation Category is defined by IEC 664 and is based on the
amplitude of transient or impulse voltage that can be expected from
the AC power distribution network. This product is classified as
INSTALLATION CATEGORY II, abbreviated “CAT II” on the
instrument front panel.
Do NOT substitute parts or make any modifications without the written
approval of Audio Precision. Doing so may create safety hazards.
This product contains lithium batteries. Dispose only in accordance
with applicable regulations.
This product is for indoor use - pollution degree 2.
