Figure 6. Control Keyboard
The following is a description of SE-2783s or 3005As
Control Keyboard. From this keyboard, each function of
SE-2783 or 3005A can be selected. ONCE A KEY HAS
BEEN DEPRESSED, IT MAY BE RELEASED. With the
possible exception of the "" and "" keys, it is not
necessary to hold the key depressed. SE-2783 or 3005A
reacts as soon as the key is depressed, and remains in
that mode until another key has been depressed.
The Reset Key will place the SE-2783 or 3005A in the
"power-up" mode. Often times when an engine is
cranked, the battery voltage will drop below the 9 volt
minimum required to operate the SE-2783 or 3005A. To
place the instrument into proper operation after this has
happened, release and de- press the "RST" Key.
NOTE: The "RST" key is a latching key and will
remain down until depressed again - to release it.
The key must be depressed when the instrument is
This key is a latching key used on 2 cycle engines. It

This test key has two functions. Each time the SE-2783
or 3005A is connected to a power source, this key MUST
be depressed before any other
function can be selected. This places the SE-2783 or
3005A in an operational mode.
Additionally, each time "TST" is depressed, the SE-2783
or 3005A checks to see if a signal is being received from
the transducer. If a signal is being received "8888"
appears in the lighted display. If the display shows "- - - -
," a problem exists.
This key when depressed, places the SE-2783 or 3005A

This key functions during the "ADV" mode. In the
ADVANCE mode, it will increase or increment the
advance angle by one if it is depressed and re- leased
quickly. If it is depressed and held for greater than one-
half second, the advance angle will be incremented by
one; then at the end of one- half second, it will begin to
slew or increase at a rate of four degrees per second for
as long as the key is depressed. When the key is
released, the display shows the accumulated advance
This key is identical to the "" key in operation, but when
