3.1 Reverse Override Function (ROF)
In some RV’s, a TV monitor is used in conjunction with a camera which allows
the driver to view the area behind the vehicle while reversing. If the TV monitor is
in view of the driver, it should remain off, and should only be turned on when the
vehicle is reversing. When the gear is shifted to “reverse”, a micro-switch in the
reversing mechanism of the vehicle generates a “+” battery voltage signal that
can be used to switch on the TV monitor. This is termed as Reverse Override
Function (ROF). If the TV monitor is powered from the inverter, “ROF” function
will enable to switch on the inverter when the vehicle is reversed and the “+”
battery voltage signal is fed to the remote.

In the preset condition of “ROF”, when the “+” battery voltage signal
from the vehicle’s reversing gear system is fed to the ¼” male
disconnect terminal, the inverter is switched on. When the “+” battery
voltage signal is removed, the inverter is switched off.
3.2 Ignition Lockout Function
Some low power circuits in a vehicle are energized when the ignition switch is
turned to the “Accessory” position to provide “+” battery voltage power to run low
power devices such as a portable music device. If the vehicle is not running, high
power devices should not be powered as the starter battery will get drained and
the vehicle may not start. When the ignition switch is turned to the “Accessory”
position, a “+” battery voltage line is available for actuating the required devices.
As the inverter is a high power consuming device, it should be switched off when
the ignition switch is turned to the “Accessory” position. Hence, the “Ignition
Lockout” function is utilized to switch off the inverter when “+” battery voltage
signal is fed to the Remote on activation of the “Accessories” circuit.
In the back of the Remote Control, a ¼” male quick disconnect terminal is
provided to switch on or switch off the inverter by feeding “+” battery voltage
signal. A jumper is provided in the Remote (the jumper is accessible after
opening the bottom cover of the remote control) to select either “ROF” function or
“Ignition Lockout” function. The Remote Control comes preset in “ROF” position.

When the alternate “Ignition Lockout” function is selected (by changing
the position of the internal jumper), the inverter shuts down when “+”
battery voltage signal from the “Accessories” circuit is applied and
switches on when the “+” battery voltage signal is removed.
