Basic maintenance procedures
Cleaning
A non abrasive cleaning cloth should be used to clean the displays. Use plenty of water to
resolve and take away salt remains. Crystallized salt may scratch the coating if using a damp
cloth. Apply minimal pressure to the screen.
Where marks on the screen can’t be removed by the cloth alone, use a 50/50 mixture of warm
water and isopropyl alcohol to clean the screen. Avoid any contact with solvents (acetone,
mineral turpentine etc.), or ammonia based cleaning products, as they may damage the anti-
glare layer, plastics bezel, or rubber keys.
Always fi t the supplied protective sun cover when the displays are not in use.
Checking the keys
Make sure that no keys are stuck in the down position. If one is stuck, wiggle the key to free it
back to normal.
Checking the connectors
The connectors should be checked by visual inspection only.
Push the connector plugs into the connector, if the connector plugs are equipped with a lock;
ensure that this is in the correct position.
Software upgrades
Please contact your local dealer if you wish to upgrade your processor. A list of B&G approved
dealers can be found at www.bandg.com
Through-hull housings
Keep the screw threads of through-hull housings well greased with silicone or water pump
grease. Ensure that the outer surfaces of the housing are properly coated with anti-fouling
paint.
Boat speed sensor (paddlewheel type)
Use a stiff brush to remove marine growth that may cause the paddlewheel to freeze, and
then clean the surfaces with a very weak solution of household detergent. If fouling is very
severe, push the paddlewheel axle out by using a small drift, and then very gently, wet sand
the surface with a fi ne grade wet/dry paper.
Inspect the o-rings on both the sensor and the blanking plug and replace if necessary, and
then lubricate with silicone lubricant or petroleum jelly (Vaseline®).
