<Restriction on wide angle in the front section>
Note1) If the angle of axis J1 is 170 degree ＞ J1 ＞ 125 degree,
the operating range of axis J2 is limited to 125 degree ＞ J2＞ -90 degree.
Note2) If the angle of axis J1 is -125 degree ＞ J1 ＞ -170 degree,
the operating range of axis J2 is limited to 130 degree ＞ J2 ＞ -90 degree.
<Restriction on wide angle in the rear section>
Note3) If the angle of axis J2 is -30 degree ＞ J2 ≧ -60 degree,
the operating range of axis J3 is limited to a range
that satisfies both 4 x J2 + 3 x J3 ＞ -180 and 171 degree ＞ J3 ＞ -20 degree.
Note4) If the angle of axis J2 is -60 degree ＞ J2 ≧ -90 degree,
the operating range of axis J3 is limited to a range
that satisfies both 2.7 x J2 + 3 x J3 ＞ -142 and 171 de
ree ＞ J3 ＞ -20 de
ree.
