snom PA1 User ManualSafety, Disposal, Cleaning of Product
Important information
Please read the instructions on safety and disposal and on how to set up and use the device before
using it and also give them to other users to read or inform those users of their contents. Save this
manual and do not give the device to third parties without it.
Safety instructions
Follow the instructions in this manual and other applicable documentation of the device.
• If the device is not supplied with power via an Ethernet cable, use only a power adapter expressly
recommended by snom technology. Other power supplies may damage or destroy the device,
affect its behavior, or induce noise.
• Avoid placing the cables where people may trip over them or where they may be exposed to
mechanical pressure as this may damage them.
• This device is for indoor use only! NOT FOR OUTDOOR USE!
• Do not install the device in rooms with high humidity (for example, in bathrooms, laundry rooms,
damp basements). Do not immerse the device in water and do not spill or pour liquids of any kind
onto or into the device.
• Do not install the device in surroundings at risk for explosions (paint shops, for example). Do not
use the device if you smell gas or other potentially explosive fumes.
• Do not use the device during thunderstorms. Lightning striking the power grid may cause electric
shocks.
• Do NOT remove the device's power supply (Ethernet cable when using PoE, power adapter when
not using PoE) when the red light is on or blinking; a firmware update is ongoing. Cutting off the
device's power during a firmware update (red LED on, green LED off) will damage the firmware and
render the PA1 inoperational. In such cases, it will need to be returned to the vendor for resetting.
SELV (Safety Extra Low Voltage) compliance
Safety status of Input/Output connections comply with SELV requirements.
Warning: To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits
to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and
PSTN ports contain TNV circuits. Some LAN and PSTN ports both use RJ-45 (8P8C)
connectors. Use caution when connecting cables.

1. Use the measurements in Fig. 1 to mark the positions of the four holes to be drilled in the wall, or
use the template at Appendix 1.
2. Drill the holes and insert the expansion anchors in the holes.
3. Place the snom PA1on the wall with the cut-outs above the anchors as shown in Fig. 2.
Fig. 2
4. Place the screws in the anchors and tighten them evenly..
Connecting the PA1
Fig. 1 Fig 2
1. Plug the Ethernet cable into the RJ45 connector labelled "Port 1PoE", as shown in Fig. 1. The
second RJ45 connector labelled "Port 2" is for daisy-chaining further Ethernet devices without the
need for another Ethernet cable.
If no PoE available: Connect a snom-approved 5 V 10 W power adapter to the power
connector labelled "5V DC".
2. Connect the loudspeaker wires to the speaker terminals labelled "Speaker", as shown in Fig. 2.
Connect the "+" wire with the red terminal, connect the "-" wire with the black terminal.
Note: If you want to use a headset during the setup:
Connect the headset's microphone plug to the jack labelled "Mic-In".
Connect the headset's speaker plug to the jack labelled "Line-Out".
