To keep PowerStick running for many years, here are a few important tips:1. BOAT:A. Inspect navlight port to ensure:A1. Port is fully tightened down.A2. Correct size screws (screw head fills holes)A3. Make 100% sure there is NO corrosion on the pins in the navigation light port. (The port you plug in your white anchor/running light or your red/green bow light port.) Then apply dielectric grease on the pins to keep them sealed from moisture and air. 2. POWERSTICK: A. Do NOT allow PowerStick to be partially or fully submerged. It is ok to be in the rain while in use, if you use Silicone Rainproof Putty. If you do not have Silicone Rainproof Putty, do not use PowerStick in the rain.B. It is VITAL to keep moisture and air away from the electronics and connectors. Apply dielectric grease to the 2-USB Connectors on the PowerStick and the two sockets at the bottom. These two sockets contain the PowerSprings, which is where power is pulled from the cranking battery. Look at the PowerSprings and ensure they are corrosion free, in good condition and the springs fill 75% of the socket. (Once dielectric grease is applied to the USB connectors, close the USB covers. If the PowerSprings do not fill 75% of the socket, they may need adjustment.)C. Keep USB covers closed when not in use. This will help prevent air moisture from getting in.D. Do NOT store the PowerStick on the boat. Store inside your home where humidity and temperatures are controlled. It is best to store your GoPro, SD card, PowerStick and other electronics inside.3. SALTWATER:As all our saltwater friends know, SALTWATER WILL DESTROY EVERYTHING over time. It is VITAL you follow these steps:A. Make sure ALL steps #1 and #2 above are followed closely.B. You must be using Silicone Rainproof Putty on EVERY saltwater trip. This will keep air, moisture and salt out of the ports.C. Once you come in from fishing or other saltwater adventures, make sure your Silicone Rainproof Putty is intact and ready for fresh water spray. D. Spray fresh water as a fine mist from your camera all the way down the PowerStick. Do NOT spray upwards, keep a downward spray and movement. Do this at least twice, but good to do this 3 or 4 times.E. Remove PowerStick and hold the stick straight up and down. Spray up into the bottom with fresh water for a few seconds.F. Stand PowerStick upright for 15 minutes to dry.G. Apply a new coat of dielectric grease to both USB ports & the PowerSprings. (The little springs in the two sockets at the bottom of the PowerStick.)H. Store PowerStick in your home where the humidity and temperature are controlled. Do NOT store PowerStick on your boat.
