Grounding
If your LAN covers an area served by more than one power
distribution system, be sure the associated safety grounds are
securely interconnected.
Caution!
LAN cables may occasionally be subject to hazardous
transient voltages (such as lightning or disturbances in the electrical
utilities power grid). Handle exposed metal components of the
network with caution.
Servicing
No user-serviceable parts are inside this product. Any servicing,
adjustment, maintenance, or repair must be performed by service-
trained personnel only.
Power Adapter
The phone is a PoE phone. If the phone is not supplied with power
via an Ethernet cable, an external power adapter must be used. Use
only the power adapter expressly recommended by Hewlett-Packard
(HP 5V external power supply, J9767A).
Caution: A 48V supply, as used
by other IP phone vendors, will permanently disable this phone.
Magnetic Earpiece
Caution:
The earpiece of the HP 4110 has a strong magnetic field that
can attract ferromagnetic objects, such as pins, paperclips, staples,
thumbtacks, and other metallic items. Be careful when the earpiece
is near these objects. Sharp objects that adhere to the magnets
in the earpiece may result in cuts or injury to the ear, face, and/or
hands.
Miscellaneous
■
Avoid placing the cables where people may trip over them or
where they may be exposed to mechanical pressure, as this
may damage them.
