Section 4
Normal Procedures
A momentary pause must occur between
each push of the STBY PWR button. If the
second push of the button occurs too
quickly, it will not be recognized. If the pro-
cessor detects only one push of the STBY
PWR button the standby battery will be
latched on and continue to power the indi-
cator. This will cause the standby battery to
completely drain if not turned off by a sec-
ond push of the button. If the standby bat-
tery is allowed to completely drain, it will
have to be removed and serviced prior to
the next flight. The airplane power will not
adequately recharge a completely drained
battery.
