5.11. Special Notice for Waterproof Installation

Most problems of waterproof installation for the outdoor units are caused by the loose connections due to

vibration or other forces, under this condition, it is possible for the moisture to penetrate into the main unit

from the connector. The following procedures are recommendations for outdoor waterproof installation.

Step 1. Ensure that you already fasten all connectors tightly.

Step 2. Tightly wrap two layers of self-bonding insulating tape forward and backward over the physical

connection (the tape from a good brand is recommended). Extending two inches beyond the

connectors or beyond the end of heat-shrinkable tubing on the RF coaxial cable and overlapping the

tape on each turn are also required for better waterproof installation.
