Associating a transmitter and a receiver in a supplemental remote control system for materials handling vehicles

A method of associating a transmitter and a receiver in a supplemental remote control system for materials handling vehicles comprising:

• initiating a power on sequence to enable a materials handling vehicle for operation, said materials handling vehicle having a receiver for receiving wirelessly transmitted travel commands;
• pairing said receiver and a corresponding controller on said vehicle to a select one of a plurality of wireless remote control devices comprising:
• receiving pairing mode confidence signals at said receiver of said vehicle, wherein each pairing mode confidence signal provides a transmitter identification code that uniquely identifies a corresponding one of said plurality of wireless remote control devices within range of said receiver;
• and
• matching a known transmitter identification code associated with said select one of said plurality of wireless remote control devices with a corresponding one of the pairing mode confidence signals received by said receiver comprising;
• synchronizing said select one of said plurality of wireless remote control devices to said receiver and said controller of said vehicle such that said materials handling vehicle acknowledges remote travel commands from said select one of said plurality of wireless remote control devices;
• storing a receiver identification code that uniquely identifies said vehicle in said select one of said plurality of wireless remote control devices;
• clearing said receiver identification code stored in said select one of said plurality of wireless remote control devices when said select one of said plurality of wireless remote control devices is installed in a corresponding charging station;
• and
• clearing said transmitter identification code stored in said controller on said vehicle after powering down said vehicle.
