Operation
(c) If the dot or any of the  ashing lightning
bolts
do not appear, make sure the TEST
button is completely covered with a gloved
 nger so no light shines on the photoreceptor
and there is adequate light (provided either
by a  ashlight or the sun) to power the test
circuit. If the dot
or any of the  ashing
lightning bolts
still do not appear, the
VOLTAGE indicator may be damaged. Test
for voltage using an alternate method.
See Figures 34 and 35.
PHASE indicators
Figure 35. If one or more PHASE indicators does not show a
flashing lightning bolt during testing, the VOLTAGE indicator
may be damaged. Test for voltage using an alternate method.
Figure 34. The absence of a dot in the Test window indicates
the VOLTAGE indicator is not in Test mode.
