- Page 13 FREQUENTLY ASKED QUESTIONS Q. Is the PDC25 waterproof? A. The Projecta PDC25 is designed to be dust and weather proof. Normal use including river crossings and light engine washing will not pose any problems. Direct high pressure washing of the PDC25 unit may cause some water damage and will not be covered under warranty.
- Page 14 Q. What is Surface Charge? A. Batteries unused or left discharged for some time build up a resistance to being recharged. When the charger is first connected, these batteries will take a surface charge, and the ‘FULLY CHARGED’ LED will illuminate within a short period of time.
