Troubleshooting
Maintenance
Occasional cleaning of the lenses will ensure optimum light output. Take care when cleaning lenses, although very
impact resistant, polycarbonate scratches easily. Clean the lens and base with soap and water or a lens polish
using a microber or other lint free soft cloth. Do not use solvents as they may damage the polycarbonate.
Lens Removal and Installation
1. Identify the lens(es) to be removed - not all lenses need to be removed to access the internal components.
2. Unfasten the retaining screws from the lens(es) of the lightbar - the screws can be left captive in the lens.
3. Carefully lift the lens off the seal – choose a suitable location to temporarily store the lens so as to not scratch
the surface.
4. When reinstalling, gently apply pressure around the upper lens taking care not to damage the seal around the
lower lens set. Retorque the retaining screws to 18 IN-LB (2.0 N-M).
All products are thoroughly tested prior to shipment. However, should you encounter a problem during installation
