5. For concrete-type pit boxes, it may be necessary to use a screw anchor. Choose an anchor appropriate for
a #10 pan head screw.
Caution Do not over-tighten the mounting screws. Over-tightening the mounting screws may break the
ERT module mounting tabs.
6. Start a screw into the pilot hole. Using the top hole of the ERT module, set the ERT module over the
screw head and slide it down so the screw is now at the top of the notch (as shown). Carefully tighten the
screw until snug. Over-tightening the mounting screw could crack the ERT module housing.
Note If mounting requires a screw anchor, mark the location of the bottom anchor and remove the ERT
module. Drill the required mounting hole, insert the anchor, and re-attach the ERT module.
7. Holding the ERT module in the upright position, drill the second pilot hole. Use the bottom mounting hole
as a template.
Caution Any ERT module position other than upright may negatively affect radio performance and
battery life.
8. Screw the bottom screw into the pilot hole until snug. Do not over-tighten the mounting screw.
