then monitors for a voltage increase which occurs when the alternator has output. This
circuit automatically compensates for voltage, temperature and the amount of time since
the vehicle was last operated. The Smart Tach
TM
feature is preset at the factory, and if
utilized, the Orange wire is not used. Note that when using this method, if the engine is
hard to start, Programmable Feature #3 will allow 50% more starter time.
Tachometer Sensing:
This method requires connection of the Orange wire. If the vehicle is generally hard to
start (requiring the starter to be engaged for more than 1 second) this method will produce
more consistent remote starting. With this method the Orange wire reads the engine speed
(tach) information from a wire in the vehicle. The Orange wire connects to the vehicle's
tach wire, which is found in the engine compartment, although in some cases it may also
be located inside the vehicle. To use a multimeter to verify the correct tach wire, set it for
AC Volts scale. The correct wire will read 1 to 6 volts AC with the engine idling, and will
increase with engine speed. Once the Orange wire connection has been made, this proce-
dure must be followed:
1)
Turn the Override Switch OFF. Wait 5 seconds for the Diagnostic LED Light to
stop flashing. Press the Left Control Button once and the light will respond with
one flash. Now push the Right Control Button once. The light will flash once
again (If the light flashed twice, press the Right Control Button again until only
one light flash is seen).
2)
Wait 5 seconds for the Diagnostic LED Light to flash 3 times.
3)
Turn the Override Switch back to the ON position.

The RS-4LX has 8 features which can be turned on or off to meet installation require-
ments or to enhance the unit's operation. The factory settings are adequate for most instal-
lations. The Left Control Button, Right Control Button and Diagnostic LED Light are
used to change the settings of the programmable options. The Programmable Options are:

The RS-4LX features a built-in diagnostic routine which will indicate why the unit
turned the engine off the last time the unit was used. To use the diagnostic mode, turn the
Override Switch OFF. A few seconds later, the Diagnostic LED Light will flash in the
following fashion to indicate what caused the engine to turn off:
1 flash - normal 10 or 15 minute time cycle expired.
2 flashes - brake was pressed or the hood was opened.
3 flashes - no tach signal or the engine stalled.
4 flashes - received another remote input from the transmitter.
5 flashes - transmission selector was removed from "Park".
6 flashes - low battery voltage or an additional ignition may be needed.
8 flashes - too high of a current draw one of the system's transistor outputs.
12 flashes - the Override Switch was turned off.
