5. Check that the instrument make and model marked on the side of the instrument and on the invoice
are correct before starting the installation. A R-1-6 is used on a 6-cylinder engine and a R-1-4 is
used on a 4-cylinder engine. The R-1-?S1 or R-1-?S2 is to be used on a Lasar ignition system (or
any system with a tach out). Also, check the invoice for proper tach time.
6. Check that the limit information on this instrument matches the published limits in your aircraft's
P.O.H. or Flight Manual. Also, this information may be listed in the T.C. Data Sheet for your
aircraft. Any AD's and/or STC's may set forth additional limitations on the operation of your
engine. The limit information listed in the AML is for unmodified aircraft and is intended for
reference only. It is the aircraft owner's and/or installer's responsibility to determine

On the front of this instrument you will find a red light marked with the maximum RPM informa-
tion. If there are any additional red or yellow lights on this instrument, the operating range of these
lights can be found on a sticker located on the side of the instrument (see the AML at the back of
this manual to decode this information). This instrument designates any "Caution Range" with
yellow LEDs, any "Maximum and Minimum Limits" with Red LEDs and the "Safe Operating
Range" with green LEDs. The "Safe Operating Range" on this instrument is equivalent to the green
"Normal Operating Range" and any unmarked areas on a analog gauge.
Do not attempt to remove or replace the limit stickers on this instrument. If the RPM limits for your
engine do not match those which are marked on this instrument send this unit back to Electronics
International Inc. for re-calibration. DO NOT install or use a primary engine instrument

7. Before starting the installation make sure the unit will fit in the location you intend to install it
without obstructing the operation of any controls.
8. If this instrument is to replace an existing unit in the aircraft, it is the installer's responsibility to
move or replace any existing instruments or components in accordance with FAA approved meth-
ods and procedures. The following Installation Instructions do not cover moving or the removal of
any existing instruments or components.
Route The Circular Connector: Route The Circular Connector: Route The Circular Connector: Route The Circular Connector: Route The Circular Connector:
Starting from under the instrument panel, route the circular connector end of the wire harness up to
the instrument mounting location. (See the wiring diagram at the back of this manual). Place the circular
connector about 8 inches back from the panel. Tie wrap the harness in place approximately 1 foot back
from the circular connector. This will allow the harness to be flexible and accommodate varying lengths in
instrument wires. Be sure these wires do not obstruct the freedom of travel of any controls.
Be sure these wires do not obstruct the freedom of travel of any controls. Be sure these wires do not obstruct the freedom of travel of any controls. Be sure these wires do not obstruct the freedom of travel of any controls. Be sure these wires do not obstruct the freedom of travel of any controls.

On the back of the mag switch will be a number of lugs. Locate the two lugs connected to the left
and right mag leads (P leads). Connect the two isolators supplied with the kit to these lugs (see wiring
diagram). When installing these isolators do not remove the existing mag leads (P leads). These isola-
