Troubleshooting
Cleaning
The most important cleaning task is to remove accumulations of dust and lint from
the radiator fins. An extensive collection of dust and lint on the cooling fins will
interfere with the efficient dissipation of heat.
When dirt and dust have accumulated in the radiator fin spaces it should be cleaned.
Preparation:
s Material: Lint-free cleaning cloth
s Mild detergent
To clean the unit follow the instructions below.
1. Gently remove loose dirt and grime using a soft clean cloth dampened with a mild

2. Check the condition of the RF coaxial connector. If it needs cleaning, clean the
connector with a self-drying contact cleaner, that leaves no residue on the inaccessible
portions.
