of table X. The readouts on the commanders control shall be as speci -
fied in table X to determine compliance with 3.3.1.5.2.
4. 6.7 Ranging - laser firing
4. 6.7.1 Minimum range test. Perform five ranging operations

outs. The readouts shall be the actual target range within the specified
range accuracy to insure compliance with 3.3.1.6a.
4.6.7.2 Maximum range test. Connect A77J5-r to A77J5-e and
place neutral density filters over the receiver ape aperture with an attenua -
tion of 37 + dB. Perform 10 ranging operations against Target No. 3
(item 12 in table VIII). The target shall be flat, normal to the laser
Observe the-range readouts. At least 9 of the 10 readouts shall be the
