BAT TERY POWER BELTS
110V, AC BELT
— Solid state Crystal Controlled Inverter powered by 9 NiCad rechargeable batteries with built-in charger.

— uses most advanced CMOS logic
— short circuit and overload proof — no fuses or circuit breakers
— automatic warning sound when batteries running low
— unit cuts off before any cells can have reverse polarity applied — No switches or buttons to operate
— cannot run at incorrect frequency
COLD WEATHER FILMING
The advantage of the 110V, AC 60 Hz belt system over a DC crystal controlled system in sub-zero temperature filming is that there are no electronic parts on the synchronized motor of the exposed camera. The motor can only run at the speed corresponding to the frequency, or not at all, unlike a DC system where mechanical overloads can lead to cumulative errors which are not corrected. The only electronic parts involved are on the power belt. The belt can be worn comfortably under the cinematographer’s clothing for increased battery endurance and highest sre ERGY Becuracy at very low temperatures.
