THE "OVAL" CONTROL OPERATING GUIDE
1. Power up the boat's main DC service and turn on the trim tab circuit breaker. The "Oval"
will come up on standby but no LED's will be lit.
2. Turn on the switch provided by the installer which wakes up the "Oval" and puts it in service. The "Oval" will
initiate a 10 second calibration sequence to synchronize the tabs and indicators at full retract, ready for use. The
display will show one tab position LED, on both sides, blinking at the top, to indicate both tabs are up.
3. The top portion of the Left switch is marked Port/Bow Down. Pushing this switch deploys the right tab and its
movement is indicated by the Left set of the red LED's. All LED's lit is down. The other 3 switches operate in
the same manner, for port and starboard, bow up and bow down. These switches can be pushed individually,
simultaneously or cross controlled, as appropriate.
4. The spot at the top center is an automatic dimmer for the tab position LED's, for nighttime operations.
5. At trip's end, when the switch which turned the "Oval" on, is turned off, the "Oval" will again initiate a 10 second
calibration sequence to synchronize the tabs and indicators at full retract, and the "Oval" will revert to inoperative
standby, with a 20 ma current draw.
6. If the "Oval" does not appear to be operating correctly, refer to the installation guide on the reverse side for
installation insight, or call 888-LECTROTab for assistance.
7. When leaving the boat, turn off the boat's main D.C. service to turn the 20 ma standby current off.
