2.2.5 Channel Changing (can only be peformed if boards have been associated)
While in the ping pong mode, the current channel can be changed to one of
four other unique channels (four channels total). This is accomplished by
holding the push button for approximately two seconds, at which point the
yellow LED (LED2) will be lit steady. Once the push button is released, the
current channel option number (one through four) is displayed by a series of
flashes on the red LED (LED3). Each short push button press will increment
the channel option number and display it with a given number of flashes on
the red LED (LED3). To accept the last selected channel, hold the push
button until the yellow LED (LED2) goes out (approximately two seconds).
After again releasing the button, the device will return to the ping pong mode.
Note that both the master and slave devices must be set to the same
channel option number for the pair to communicate, and each board must be
individually set to that given channel option number.
