Mechanical Shutter Speeds: If batteries fail and you're caught without spares, manual exposures without the meter can be made at the "125X" (1/125 sec.) and "B" mechanical shutter speeds. See page 17. Battery Check for TTL Electronic Focusing System: See page 37. Battery Care: • Battery life will vary from a short time to several months depending on the frequency of operation of the electronic exposure and focusing systems. Should batteries require replacement, replace all four with equivalent 1.5 volt silver oxide batteries (Eveready S76, MALLORY S76E, etc.) • Do not mix battery brands and types, nor old batteries with new batteries. (This is dangerous and could actually shorten battery life). • Wipe the battery with a dry cloth before insertion and always handle by the edges to ensure proper contact. • Keep spare batteries on hand to help avoid the inconvenience of battery failure during busy picture-taking sessions. When shooting in cold climates where temporarily failure due to extreme temperatures is not uncommon, keep spares in a warm pocket. • When not using the camera for long periods of time, remove batteries to protect against leakage.
