The following should clear away any haziness of the T-70 backup battery change question as well as the LCD display. It's straight out of the T-70 manual, page 70. Liquid Crystal Display ---------------------- The T70's display panel uses liquid crystal to indicate exposure information. After about 5 years of normal use, the display may become hard to read. Back-up battery --------------- The T70 has a built-in back-up battery which memorizes the display panel data, such as the frame counter number and the ISO film speed, when the AA size batteries are taken out for replacement. Battery life is about 5 years. When voltage becomes insufficient, "ISO 100" will blink (at 2 Hz) on the display panel after loading batteries for normal camera operations. If the back-up battery is removed, the memory will be erased. In this case, reset the film speed. Take your camera to the nearest Canon Service facility for the replacement of the liquid crystal or the back-up battery. ----------- The main batteries will last for 20 (NiCad) to 40 (Alkaline) 36-exposure rolls in normal temperatures, so you can be assured that you can take this many shots before worrying about battery failure. And even if the battery fails, you're OK as long as you change your main (AA) batteries at the end of a roll and reset the film speed after changing them. In any case, I'm replacing my backup battery and LCD after four years, just to be on the safe side... \tom haapanen watmath!watdcsu!haapanen Don't cry, don't do anything No lies, back in the government No tears, party time is here again President Gas is up for president (c) Psychedelic Furs, 1982

An earlier article on this subject mentioned that Canon should tell in its
ads about the battery. Actually this is somewhat true: the booklet available
from photo dealers describing the camera in detail to potential customers
actually SHOWS a photograph of the battery, which is located on one side
of the prism on top of the camera.
That booklet, incidentally, contains a lot of interesting technical data that
is not in the user's manual (a block diagram of the control logic, photos
of the inside of the camera, etc); I recommend it to T70 owners who don't
already have it. It's interesting to see how much control the CPU has over
the camera, and how much data is available to it.
