dealer or local power company.
8. Do not allow anything to rest on the power cord. Do not install this product where
the cord may be walked on.
9. Never push objects of any kind into this product through the slots in the base unit
or wireless mic because they may touch dangerous voltage points or create a short
circuit. Never spill liquid of any kind on the product.
10. To reduce the risk of electric shock, do not disassemble this product, but take it
to an authorized service facility. Opening or removing parts of the base unit or
wireless mic other than specified access doors may expose you to dangerous
voltages or other risks. Incorrect reassembling can cause electric shock when the
product is subsequently used.
11. Do not overload wall outlets and extension cords.
12. Unplug this product from the wall outlet and refer servicing to an authorized

common event associated with the closing of any electrical circuit. The user should
not plug the phone into a power outlet, and should not put a charged wireless
mic onto the charging cradle, if the phone 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; gasoline vapors; etc.); a leak of natural gas; etc.
15. Only put the wireless mic next to your mouth when it is in normal talk mode.
16. The power cables 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

available, use AC power, as shown below.
Note: the conference phone requires a network connection to an IP PBX to operate.
This manual assumes that your network infrastructure is established and that your
IP PBX phone service has been ordered and configured for your location.

through the slots.
2. Plug one end of the Ethernet cable into the LAN jack of the power adapter, and plug
the other end into a network switch or router.
3. Plug the small end of the AC power cord into the power jack of the adapter, and
plug the large end into a wall outlet not controlled by a switch.
• The supplied power adapter is designed for use with only the Conference phone . It
is not designed to power other network devices. Do not connect the supplied power
adapter to any other network devices through the supplied DC power cable or any
other Cat5e ethernet cable.
• The AC power cord is intended for a vertical or floor mount position. The prongs are
not designed to hold the plug in place if it is plugged into a ceiling or cabinet outlet.

Insert the battery (with the label THIS SIDE UP facing up) into the battery
compartment.
2. Slide the battery door until it clicks into place.

Getting Started
Before use
Check for dial tone
• Press . If you hear a dial tone, and see that the status indicator turns green on the
base unit, the installation is successful.
If you do not hear a dial tone:
• Recheck the installation diagram and the connections to the unit.
• Ensure the unit is correctly configured with the correct SIP account information.
For more information, see the C520-WiMi Administrator and Provisioning Guide,
available at www.snom.com.
• Consult your service provider if you require additional user accounts or if you
suspect a service disruption is at fault.
Operating range
The maximum range between the conference phone and its wireless microphones and
any connected speakerphones can vary, depending on their locations and the layout of
your oce.
When a wireless microphone is out of range, it must be returned to the charging cradle
to be able to reconnect with the phone.
If there is an incoming call while the wireless microphone is out of range, its green call
LED will not flash to indicate an incoming call. If the wireless microphone is moved
out of range during a telephone conversation, there may be interference. To improve
reception, move it closer to the conference phone.
