Mode-B
The indicator light 1 will light for a lamp check (2 seconds) and
•
then become an engine run time indicator light. Note, however, that
even while the indicator light is lit to indicate the engine run time,
holding down the S-HAC switch 2 for more than 0.7 seconds will
cause the indicator light 1 to switch to slow flashing (mode-A).
Holding down the S-HAC switch 2 for more than 1.8 seconds will
cause the indicator light 1 to switch to fast flashing (mode-B).
Releasing the S-HAC switch 2 to select mode-B will cause the fast
•
flash pattern to continue.
NOTE:
• After holding down the S-HAC switch to switch from mode-A (slow
flashing) to mode-B (fast flashing), holding down the S-HAC switch
again will only select normal mode.
• To switch from mode-B to mode-A, first switch to the normal mode
and then switch to mode-A.
• To switch to the normal mode from mode-B, hold down the S-HAC
switch until the indicator light 1 goes out.
