When using the conference phone , basic safety precautions should always be followed
to reduce the risk of fire, electric shock and injury to persons, including the following:
1. Read and understand all instructions.
2. Follow all warnings and instructions marked on the product.
3. Unplug this product from the wall outlet before cleaning. Do not use liquid or
aerosol cleaners. Use a damp cloth for cleaning.
4. Do not use this product near water such as near a bathtub, wash bowl, kitchen sink,
laundry tub or swimming pool, or in a wet basement or shower.
5. Do not place this product on an unstable table, shelf, stand or other unstable
surfaces.
6. Slots and openings in the back or bottom of the base unit and wireless mic are
provided for ventilation. To protect them from overheating, these openings must not
be blocked by placing the product on a soft surface such as a bed, sofa or rug. This
product should never be placed near or over a radiator or heat register. This product
should not be placed in any area where proper ventilation is not provided.
7. This product should be operated only from the type of power source indicated on the
marking label. If you are not sure of the type of power supply in your oce, consult your
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
service facility under the following conditions:
• When the power supply cord or plug is damaged or frayed.
• If liquid has been spilled onto the product.
• If the product has been exposed to rain or water.
• If the product does not operate normally by following the operating
instructions. Adjust only those controls that are covered by the operation
instructions. Improper adjustment of other controls may result in damage
and often requires extensive work by an authorized technician to restore the
product to normal operation.
Important safety instructions
ii

• If the product has been dropped and the base unit and/or wireless mic has been
damaged.
• If the product exhibits a distinct change in performance.
13. Avoid using the conference phone during an electrical storm. There is a remote
risk of electric shock from lightning.
14. Do not use the conference phone 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 wireless mic is replaced in its cradle. This is a
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
ceiling or cabinet outlet.
17. For pluggable equipment, the socket-outlet shall be installed near the equipment
and shall be easily accessible.
18. CAUTION: Use only the batteries indicated in this manual. There may be a risk of
explosion if a wrong type of battery is used. Use only the supplied rechargeable
battery or a replacement battery pack. Do not dispose of batteries in a fire. They
may explode.
19. If you are not using PoE, use only the adapter included with this product. Incorrect
adapter polarity or voltage can seriously damage the product. Base unit power
adapter: Input 100–240V AC 50/60Hz; output: 9V DC 1500mA.

Connecting
The C520-WiMi can be powered by AC power or Power over Ethernet (PoE). If PoE is not
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.
1. Plug one end of the DC power cable into the power jack of the phone, and plug the
other end into the yellow C520-WiMi jack of the power adapter. Route the cord
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.

Getting Started
To power the C520-WiMi using PoE:
1. Plug one end of the Ethernet cable into the Ethernet port on the bottom of the unit.
2. Plug the other end of the cable into your network router or switch. When the base
unit is powered up, the status indicators turn green for about two seconds.
Note: You can connect the C520-WiMi to both PoE and AC power. Ensure that you
connect the cables in the order shown in the diagram on page 2. The phone will use
PoE; if PoE fails, the phone will use AC power as a backup.
Install the wireless mic battery
1. Plug the battery connector securely into the socket inside the battery compartment.
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.
3. Place the wireless mic onto the charging cradle.
Note: The status indicator on the wireless mic turns orange when charging, and
turns o when the wireless mic is fully charged.

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 oce.
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.
