Slow flashing red LED light indicates that it is in Ignition Lockout Function selection status.

Reverse Over-ride (ROF) and Ignition Lockout Functions

The Recreation Vehicle Industries Association (RVIA) of America and some American states require that when a vehicle is in

motion, the TV monitor should be switched off if it is in the view of the driver. Sometimes, the TV monitor is used in

conjunction with a camera to enable the driver to view the area at the back of the vehicle when the vehicle is being reversed.

The TV monitor should normally remain off (if it is in view of the driver) and should power on only when the gear is shifted to

“reverse”. When the gear is shifted to “reverse”, a micro-switch in the reversing mechanism in the vehicle generates a “+”

battery voltage signal that can be used to switch on the TV monitor. This is termed as “Reverse Over-ride 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 “+” battery voltage signal is fed to the Remote.

Also, 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 low power devices like radio / CD player etc (the vehicle is not running in this position

and hence, 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 Control (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

In the preset condition of “ROF”, when the “+” battery voltage signal from the 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

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

The wire feeding the “+” battery voltage signal to the ¼” connector for the ROF or Ignition Lockout functions should have a

0.5A fuse in series for protection.

Selecting ROF or Ignition Lockout Functions

Jumper JP1 is placed inside the remote control and is used to select either Reverse Override Function or Ignition lockout

Function (open the back cover for access to the jumper JP-1).

JP1 jumper “Open” - Reverse Override Function is selected*

JP1 jumper “Short” – Ignition Lockout Function is selected

*Please note that the default mode is OPEN.
