Maintenance and Servicing
Designed to be maintenance free, the AV23 requires minimal attention, though the following
maintenance and servicing information is provided to help ensure the life of your Avlite product.
1. Cleaning Solar Panels - occasional cleaning of the solar panels may be required. Using a cloth and
warm soapy water, wipe off any foreign matter before rinsing the panels with fresh water.
2. Battery Check - inspection of batteries should be performed every three years (minimum) to ensure
that the charger, battery and ancillary electronics are functioning correctly. Using a voltage meter,
check that the battery voltage is at least 3.6 volts under 100MA load, and ensure all terminals are
clear of foreign matter.
