The fjrs:t step taken to operate the timer is to Wind the arrow until it points to the red dot in the snm button. Second, the timing ring is pushed in and then turned until the desired time is 'iet under the red dot. Third, the start button is: pushed to the left. What these operating pro~ cedures actually do can be explained by examin~ ing FigurL' 2·11. When tilt' arrow is turned, the mainspring inside the timer i!l being wound. The action of (Jle spring. while it unwinds. drives rhe arrow around. You can see (hat the spring IS also linked 10 a "ene:. of gean.. In addition to controlling the un· winding of the mainspring. the purpose of the gears 1s two-fold. One, they provide the sound

which indicates that the timer is in operation. Thls is accomplished by the revolution of the large~tooth gear as it brushes past the cutout on the wheel, It strikes the whed producing a ''wltirringn sound, The second purpose of the gears is to proVide a means by w hleb the timer can be stopped. Note that the start button is connected to a Ie\'er. Moving the button to the right (as viewed from outside the camera) causes the lever to engage the large-toothed gear. This stops the gears which. in tum, stops the main~ spring,

At the rate of speed the mainspring. unwinds. this. arc is equiVatent to 60 seconds.

Electronic Tjmer (Models 335, 350. and 360) The electronic timer (Figure 2~ 13) measures elapsed time in frames of 15 seconds to J 20 sec~ onds. It does this by measuring the time it takes to charge a capacitor in the timing circuiL Be~ cause of the power requirements of the timer, a second 3 volt battery is needed in the camera

The post on the timing ring Slops the arrow and thus determines how long the mainspring will be permitted to unwind. In Figure 2-12, you can see that the liming nng can be pushed in toward the lens since it is held in place by case springs mounted on the interior housing. By pushing the timing ring in. the serrated base is released from the metal stop on the door case. The timing ring can then be turned. Since the unwinding of the mainspring through the gears is at a set rate, the arrow speed is conslanL Therefore, timing can be established by allOWing the arrow to move through an arc which can be related to time. For example, if the dial is pushed in and set so Ihat "60" is under the red dot, the arrow will move from the "60" until it hits the plastic stop ilt "0",

If these standards are not met. refer to Section V for the method or adjusting the shutter release button.

E. MEASURING TIMER ACCURACY

If the blades. close together after having deter­ mined that the s.hutter batlery is OK. check the interlock. Fjrst, clean the interlock contacts as thoroughly as possible. Be sure the wiring is properly soldered to the confacK There should be tension evident when the top contact is lirred (with a pencil point). After making these checks. re-perrorm steps J and 2 above. If the blades slill close tOgether check the continuity between the interlock contact and the contact on the handi!uard. If this is OK and the problem re-. mainS:. consult the "Repair Manual on Models 36~. 366, and 374 Automatic Shutters." (If li Model 360. consult the "Repair Manual on the Model 360 Camera. ")'"

EJeclronic Timer: Set the timer dial to 60 and actuate the timer switch .. Using a stop-watch, measure the time interval between actuatIon and the "beep'". It must be between 58 :and 64.5 seconds. Also observe rhat the bmp tights. If the- timin!! is orr. or the lamp does not light i or no sound). replace the timer. Mechanical TImer: Set the arrow 1060 and start the rimer. Ulolng a stopwatch. measure the time interval betweell start and stop. It musl be between 54 and 66 seconds. If the timer does not perform within this specification. replace it.
