Important safety instructions
The applied nameplate is located at the bottom or rear of the product.
When using your telephone equipment, basic safety precautions should always be followed to reduce
the risk of fire, electric shock and injury, including the following:

EN - 3
15. Avoid using a telephone (other than
cordless) during an electrical storm. There
is a remote risk of electric shock from
lightning.
16. Do not use the telephone to report a gas
leak in the vicinity of the leak. Under certain
circumstances, a spark may be created
when the adapter is plugged into the power
outlet, or when the handset is replaced in its
cradle. This is a common event associated
with the closing of any electrical circuit. The
user should not plug the telephone into a
power outlet, and should not put a charged
handset into the cradle, if the telephone
is located in an environment containing
concentrations of flammable or flame-
supporting gases, unless there is adequate
ventilation. A spark in such an environment
could create a fire or explosion. Such
environments might include: medical use
of oxygen without adequate ventilation;
industrial gases (cleaning solvents; petrol
vapours; etc.); a leak of natural gas; etc.
17. Only put the handset of your telephone next
to your ear when it is in normal talk mode.
18. The power adapters are intended to be
correctly oriented in a vertical or floor mount
position. The prongs are not designed to
hold the plug in place if it is plugged into
a ceiling, under-the-table or cabinet outlet.
19. Use only the power cord and batteries
indicated in this manual. Do not dispose
of batteries in a fire. They may explode.
Check with local codes for possible special
disposal instructions.
20. In wall mounting position, make sure to
mount the telephone base on the wall by
aligning the eyelets with the mounting studs
of the wall plate. Then slide the telephone
base down on both mounting studs until it
locks into place. Refer to the full instructions
in Installation in the user’s manual.
21. This product should be mounted at a height
of less than 2 meters.
22. Listed PoE (The product is considered not
likely to require connection to an Ethernet
network with outside plant routing).
CAUTIONS
• Keep small metallic objects such as pins
and staples away from the handset receiver;
• Risk of explosion if battery is replaced by
incorrect type;
• Dispose of used batteries according to the
instructions;
• Disconnect the telephone line before
replacing batteries;
• For pluggable equipment, the socket-outlet
(power adaptor) shall be installed near the
equipment and shall be easily accessible;
• Avoid using the battery in the following
conditions:-
• High or low extreme temperatures that a
battery can be subjected to during use,
storage or transportation;
• Low air pressure at high altitude;
• Replacement of a battery with an incorrect
type that can defeat a safeguard;
• Disposal of a battery into fire or a hot oven,
or mechanically crushing or cutting of a
battery that can result in an explosion;

Appendix
Troubleshooting
If you have difficulty with the telephones, please try the suggestions below.
In case of malfunction, contact authorized service personnel, your seller, or Snom.
For cordless telephone
Question Suggestions
1. The telephone does not work at all.
• Make sure the Cat-5 network cable
is plugged into the LAN port of the
telephone base and the network wall
jack with Power over Ethernet (PoE).
• Make sure the battery is installed and
charged correctly. For optimum daily
performance, return the cordless handset
to the telephone base, charging base or
charging stand after use.
• Unplug the Cat-5 network cable from the
network wall jack. Wait for approximately
15 seconds, then plug it back in.
• Charge the battery in the cordless handset
for up to 16 hours.
• If the battery is completely depleted,
charge the battery for at least 30 minutes
before use.
• Remove the battery and then install it
again. If that still does not work, it may
be necessary to purchase a new battery.
• Disconnect the telephone base from the
network wall jack and connect a different
working SIP telephone. If the other SIP
telephone does not work, the problem is
probably in the wiring or network server.
Check your SIP server settings. Refer to
the SIP Phone Configuration Guide for
details.
• Make sure the energy-saving charging
mode is not activated. If this mode is
activated, all telephone functions will be
disabled, except battery charging.
