Mounting the Switcher
The PVS 204SA can be mounted on the Extron PMK 450 (Pole Mount Kit), which

the PMK 450 allows them to be installed in tight spaces. To install the PVS 204SA
on the PMK, follow the steps shown in the instruction guide supplied with the
PMK 450. If the PMK 450 is already installed, do the following:
1

plates of the PMK (see figure 2-1).
N

.
Placing the PVS 204SA on the PMK, align the two diagonally opposite
securing holes (located in the base of the switcher) over two suitable holes
in the floor of the PMK.
