B.2 Use the optical switches
Use the optical switches on the transmitter interface to control the transmitter display.
The Chinese-language display has three optical switches: Up, Down, and Select. You also can
use the optical switches in combinations to access different features of the display or
perform a specific task. The optical switch combinations are shown on the front of the
display, and identify the specific feature performed.
To activate an optical switch, block the light by holding your thumb or finger in front of the
opening.
Tip
You can activate the optical switch through the lens. Do not remove the transmitter housing cover. If
you hold your thumb or finger over the Up or Down optical switches without removing it, you can
activate continuous scrolling. Once you remove your thumb or finger, the scroll stops on the current
selection.
The optical switch indicator lights up when the transmitter senses that an optical switch
has been activated.
