will appear in the character display. Then press
and release the "ARROW" switch again; "SEtUP"
will appear in the display.

5. Buckle the seat belt and start the engine. Using
a hand held photo-tach or other accurate
measuring device, check the engine RPM at high
idle (full throttle). Compare the hand held tach
reading to the EIC RPM reading.
6. Press and release the "OPEN BOOK" or
"ARROW" switches to change the EIC reading to
match the tach at high idle. Pressing the "OPEN
BOOK" switch will decrease the reading and
pressing the "ARROW" switch will increase the
reading.
For best results, RPM should be calibrated at full
throttle only.
NOTE: The "OPEN BOOK" or "ARROW" switches
may have to be pressed multiple times to change the
reading, this is normal. When changing the high idle
reading, the low idle reading will have a slight
change.
To exit this item, turn the ignition key switch to the
"OFF" position to return the EIC to the Normal
Operating Mode.
