1. A remote control system for a power machine, the system comprising:
a mobile device including a processor device and a wireless communication system; and
a hand-held remote control device including a remote control communication module configured to be in communication with the mobile device, wherein the hand-held remote control device includes a plurality of operator input modules configured for manual actuation to generate operator input signals for transmission by the remote control communication module, wherein a first of the operator input modules of the hand-held remote control device is manually movable with a plurality of movement patterns corresponding to a plurality of operator input signals;
wherein the mobile device is configured to be operatively connected to the power machine by the wireless communication system of the mobile device;
wherein the mobile device and the hand-held remote control device are remotely located from the power machine; and
wherein the processor device on the mobile device is configured to:
receive an operator input signal from the hand-held remote control device via the remote control communication module, wherein the operator input signal corresponds to a first movement pattern of the plurality of movement patterns;
in response to receiving the operator input signal from the hand-held remote control device, output a command signal to a control system of the power machine via the wireless communication system to control an operation of the power machine based on operator inputs at the hand-held remote control device; and
operate in an exception mode, including applying an exception modification to the command signal to control the power machine remotely, in response to identifying that the first movement pattern corresponds to a command error at the hand-held remote control device.
