- Make sure the orientation arrow on the mounting base points up. Proper orientation is important: air must flow through the vents on the bottom and top.
-
Use the mounting holes to attach the mounting base securely. Use at least two screws (not included). The mounting holes are suitable for the most common European, American, and Asian
mounting boxes. The mounting base can be twisted on to pre-mounted screws.
CAUTION To avoid damaging the component board when you close the enclosure, make sure the screw heads do not project out of the mounting holes. CAUTION Mounting bases are tailored to the individual transmitter at the factory. If you attach several mounting bases before connecting the transmitters, store the transmitters in their original shipping boxes, so that you can match the serial number on the mounting base to the serial number on the shipping box. The mounting base of the GMW87 and GMW88 models differs from other GMW80 series models. See Installing GMW87 and GMW88.
