CORRECT EXPOSURE
Correct exposure is achieved by setting the lens f-stop) and shutter in correct combination for the film, subject, and
lighting conditions. As your RICOH TLS 401 camera has a built-in through-the-lens system CdS exposure meter, you
can adjust the exposure with a high degree of accuracy in the following manner:4www.butkus.o rg
1. Unscrew Exposure Meter Battery Compartment Cover (X) with a coin and place a battery with plus (+) end up.
(Fig. 4) The battery will last for a year or so. For replacement use Eveready EPX 625, Mallory RM 625R or
equivalent.
2. Check that the correct ASA number is set on the Film Speed Selector (G).
3. Turn "ON" the Exposure Meter Switch (N) pushing it upward. (Fig.5).
This Exposure Meter Switch is the main switch in the heart of the light sensing system. When you wind Film-wind
Lever (A) another micro-switch is turned on automatically. If you press Shutter Release Button (C), the micro-switch
is turned off automatically. When the main switch is left at ON position and the shutter is left unreleased, the
Exposure Meter Battery is consumed. Always make sure that the main switch is at OFF position whenever the camera
is not in use for a long period of time or make it a rule to always carry the camera with the shutter released. This little
care will take a new lease of the Exposure Meter Battery. The second microswitch can be seen in a little window by
winding the lever.4www.butkus.org
