Secure the Entrance (Replace/Seal the Grommet and Install Tie-Down)
1. Take the grommet that you removed and cut a notch at the bottom so that the optical and ground
wire can go through when the grommet is replaced.
2. Place the grommet back (with the notch at the bottom) and seal the grommet with tape (not
provided) and silicone sealant (not provided). Refer to Figure 12.
Caution
The grommet must be sealed so that the unit can operate correctly in an outside environment.
