A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
This system allows the shutter speed to be completely step-less and to adapt to changing light levels. SLRs would wait many years for a similar capability with off-the-film metering. The metering system can keep the shutter open for up to 30 seconds. Without a battery to power the meter, the shutter defaults to its top speed of 1/500 second.
The exposure meter uses a PX625 mercury battery, which is now discontinued.The alkaline equivalent can be used, but the different voltage, different discharge curve, and absence of voltage regulation circuit cause incorrect metering that results in between 1.5-f-stop underexposure at the beginning of the life of the alkaline battery and 1.5-f-stop overexposure at the end.
Offline/standby UPS: The green line illustrates the flow of electric power. Typical protection time: 5–20 minutes. Capacity expansion: Usually not available. The offline/standby UPS offers only the most basic features, providing surge protection and battery backup. The protected equipment is normally connected directly to incoming utility power.
Backup batteries range from small single cells to retain clock time and date in computers, up to large battery room facilities that power uninterruptible power supply systems for large data centers. Small backup batteries may be primary cells ; rechargeable backup batteries are kept charged by the prime power supply.

TADS contains stabilized electro-optical sensors, a laser rangefinder and laser target designator. The TADS assembly can rotate +/− 120 degrees in azimuth, +30/−80 degrees in elevation and can move independently of the PNVS. The movements of TADS can be 'slaved' to the head movements of the helicopter crew to point where they are looking.
Metering is powered by a ring photocell so no battery is required. Focus is manual on primary lens/viewfinder so the photographer must match the yellow/tinted image with the clear one in the primary viewfinder, then shift the eye to the auxiliary viewfinder to frame the picture when an auxiliary lens is used. 1.8 Camera weighs 710 grams (1 lb 9 ...
