Setting up the Phone
Your snom 300 is delivered with the footstand (shaded light gray
in Fig. 1) attached to the phone’s bottom shell in the position for
desktop placement. Place the snom 300 on an even, horizontal
surface that gives the rubber pads a secure grip. Do not place it
on carpets or other materials containing fibers that could block the
air vents and cause overheating.

Wall Mounting
It is also possible to mount the snom 300 on the wall. In order to
do this, detach the footstand from the bottom shell and attach it in
the appropriate position for wall mounting, as described in steps 1
through 4, below.
Make sure that the handset cord has been clipped correctly into
the groove on the bottom shell of the phone, as shown in Fig. 1.
Failure to clip the cord into the groove may result in damage to
the cord when the footstand is attached in the position for wall
mounting.
1Turn the phone upside down (Fig. 2). Please, ensure that
you do not damage the display and that you do not drop
the receiver. You may want to hold the phone in your lap
or have a second person hold it.

3Rotate the footstand 180° around its vertical axis.
4Insert the outside, rear snap-fits into the mounting
holes on the bottom shell (Fig. 4, arrow no. 1). Tilt
the footstand forward and downward until the snap-
fits snap into place in the mounting holes (arrow no.
2). Please, make sure that the four snap-fits have
securely snapped into the holes before mounting
the phone on the wall.
Fig. 4
The delivery includes a template to be used for marking the position
of the holes to be drilled in the wall.
Use wall plugs, if necessary, and screws with half-round head
profiles (diameters of screws dmax= 4.5 mm (0.177”), diameters
of heads dmax=8 mm (0.315”)).
The screws must protrude approx. 0.5 cm (0.197”) from the wall
for easy wall mounting of the phone.

Adjusting the Handset Rest for Wall Mounting
The speaker of the handset has a small, rectangular indentation
that fits over the rounded end of the plastic tab inserted into a slot
on the top shell of the phone. When the phone is mounted on the
wall, the handset must be placed on this rounded end to ensure
that it will not fall off.
Slide the tab out of the slot, as shown in Fig. 5, rotate it 180°, and
slide it back into the slot, as shown in Fig. 6.
