 The main features of the REID are shown opposite, and the following brief camera drill can be used
 to gain familiarity with the handling of the camera before loading with film.
             l.    Lift off the lens cap; holding the front milled ring, draw the lens forward and lock  it in
            position by turning to the right.
      2.  Turn the winding knsb as far as it will go.
      3.  Sight an obiect through the rangefinder (left-hand eyepiece), release the focusing lever
           from  its catch by depressingthe button, and turn the lever until the double imagesseen
           through the rangefinder coincide. The object is now correctly focused.
      4.  View the object through the viewfinder (right-hand eyepiece).
      5.  Press the release buttcn, keeping the fingers clear of the shutter speed dial.
      5.  Reverse the sequenceof paragraph 1 to return lens to  its collapsedposition, and replace
           lens cap.

The shutter speed dial will be seen to rotate when the winding knob is turned. The winding knob
winds on the film for each exposure and at the same time resets the shutter. After firing the ,hrta".,
any further Pressureon the release button has no effect until the mechanismhas been wound again.
Double exPosuresare therefore prevented. Note the action of the film counter in advancingto the
next division each time the winding knob is operated.

The slow speed dial is operative only when the main speed dial is set to
 ,,20-1"        (red figures). To set 1/20th second the slow speed dial must also
 be set to the red figure "20", and a small catch at the top of the dial locks
 it in this position. The catch may be releasedby pressingback with the
 thumb-nail as the knob is grasped. Between 1/8th and 1 second,the slow
speed dial may be set in between the engravedfigures,when intermediate
 speedswill be obtained. Time exposuresare made at "T",  the shutter
 remaining open until the slovr speed dial is turned back towards "l".

The iris diaphragm is controlled by a milled ring bearing an engraved
scale of f/numbers, towards the front of the lens barrel. Turning the
 ring to increase the f/number reduces the size of the aperture and
so less light is passedby the lens.

The distance scale may be set (or read after using the rangefinder) against
a red arrow-head index at the base of the lens mount. On either side
of this arrow-head will be seen a scale of f/numbers corresponding to
those on the iris ring. This is the depth of field scale.

The point of sharp focus being shown by the red index against the
distance scale, the depth of field scale shows, for any f/number, the
nearest and farthest distances at which obiects still remain tolerably
sharp. The marking of the scale shows that the higher the f/number,
 i.e., the smaller the aperture, the greater the depth of field obtained.
(The limits of "tolerable" sharpnessare, of course, set to an arbitrary
standard, and for those who wish to make their own calculations,the
scale is based on a circle of confusion of 0.0015" diameter.)

spool and cassette,knobs uppermost, insert both simul-
taneously into the camera. (Should the cassette not go
 right down easily,give a slight turn to the back-winding
 knob.) Note that the correct path of the film now leaves
