BATTERY PRECAUTIONS • Remove batteries when not using the flash unit for long periods of time. Batteries tend to leak if left too long in the unit and may cause serious damage. • When the ready lamp no longer lights within 60 sec. after a test flash on Manual (approx. 30 sec. on auto), it is time to replace batteries. Replace batteries earlier when shorter recycling is desired. Altough the ready lamp will still light after the test times, flash is usually insufficient for correct exposure. • Battery performance tends to deteriorate when batteries are used fl,It have been left lying around for long periods of time. Make it a point to use batteries that are fairly new. • Batteries are very sensitive to cold and performance tends to deteriorate at temperatures near freezing. Performance is restored to normal as soon as batteries are subjected to room temperatures. Keep a set of warm spare batteries in your pocket when shooting in freezing weather to substitute when the others become cold. • Battery performance tends to differ depending upon brand and type. Best results are obtained when high-performance alkaline batteries are used. Rechargeable Ni-Cd (nickel-cadimum) batteries offer the advantage of shorter initial recycling times and rechargeability, but give less number of flashes per charge. 15
