Maintenance
▪
Solar panels should be cleaned weekly (more often depending on environmental
factors) for best performance.
▪
The sign and programmer units contain no user serviceable parts. Should a malfunction
occur, please contact the supplier of the system for assistance. Any tampering with the
internal parts of the sign or programmer unit will void the warranty.
▪
The sign and programmer unit cannot be damaged by incorrect operation. If there is no
response, please check that the battery voltage is above 10 volts, then disconnect and
reconnect the communication cable on the sign.
▪
If the battery voltage is below 10 volts, the unit will need to be recharged by exposing
the solar panels to direct sunlight or connecting a suitable battery charger.
▪
The touchscreen hand controller (where supplied) is not weatherproof, and must not be
allowed to get wet. Store the controller in the weather resistant container supplied at
all times when not in use.
▪
Clean the polycarbonate screen with a damp soft, non-abrasive cloth and water to
remove any dust or dirt that may impair light clarity as needed. DO NOT use and harsh
or abrasive chemicals or cloths.
▪
Check the securing bolts are tight where the sign mounts to the trailer monthly.
▪
Perform a visual inspection of the mechanical fastenings that hold the sign head to the
mast monthly.
▪
Check the wiring and wiring glands for signs of wear or damage monthly, and replace as
necessary.
▪
Maintain wheel bearings as you would with any vehicle or trailer.
▪
Check that all wheel nuts are tightened before transporting the sign.
