MEMO HOLDER

For added convenience, your LX features a film memo holder which acts

as a reminder of the film type and number of exposures loaded in the

camera. Simply tear off the end of the film carton and insert it into the

holder frame.

SETTING THE SHUTTER DIAL

To set your Pentax LX for automatic exposure control, rotate the shutter dial until the word "Automatic" locks into place opposite the index mark as

shown. When manual control is desired, press the shutter dial lock release and turn the dial until the speed setting you wish to use aligns with the index at

the click-stop position. Indices on the dial from "2 o o o" to "2" represent fractions of a second (i.e., 1/2000th second to 1/2 second) while "1" through

"4S" represent full second increments. The "X" index setting corresponds to 1 /75th second for synchronization with electronic flash units not providing

"dedicated" flash capability with the LX camera (see page41).

Electronically-Controlled Shutter Speeds

Your Pentax LX provides electronically-controlled stepless shutter speeds in the "Automatic't mode from 1/2000th second down to 125 sec. (At ASA 100,

f/1.2) and electronically-controlled manual shutter speeds from 1 /60th second to 4 full seconds. These speeds are not functional without batteries or when

battery failure occurs.

Mechanically-Controlled Shutter Speeds

At shutter speed settings from 1/2000th second to "X" and at the "B" (Bulb) setting, the shutter operates mechanically without the need for battery power.

These speed settings should be used in the event battery failure interrupts normal camera operation.

ACTIVATING THE METER

Shutter Release Button

The feather-touch shutter release button of your Pentax LX also serves as the meter "on" switch. By pressing the shutter release lightly, both the exposure

metering system and viewfinder LED display are activated and remain on up to 25 seconds. At the end of that time, the meter and display will automatically

turn off to prevent excessive battery drain.

Shutter Release Lock

The Pentax LX has a built-in shutter lock which protects you against accidentally making an exposure or activating the exposure metering system. To

operate the lock, simply move the shutter lock lever towards the shutter speed dial until the two white dots align at the "L" setting. To disengage the lock,

reverse the procedure.
