Important Notes for Flash Photography and Maintenance (cont.)
6.Always use a fresh set of 4 AA batteries of the same brand and type when old batteries are depleted. Mixing and matching batteries of different types or brands will greatly deteriorate the flash’s performance.
7.When the flash is not being used for extended period of time (>2 weeks), remove the batteries in order to prevent battery leakage. Once the batteries are removed, do not expose the flash unit and batteries to excessive heat, sunlight or fire.
8.Charge up and test fire the flash unit at least once per month to maintain the optimal performance of the flash tube and charging capacitor.
