Checkout of the M36 and M36E1 Periscopes are done by using the flow chart procedures in this chapter.
You must do the checkout procedure from the beginning until a fault symptom is found. When it is, go to
the fault symptom index in Chapter 3. After you have corrected the fault, start at the beginning again and
do the checkout procedure until the periscope is working correctly.
