Pressing the RADIO1 (B7) and RADIO2 (B9) buttons at the same time enables automatic
headphone switching (AUTO mode). If enabled, the yellow AUTO light above the BOTH button will
be lit. Lights above the RADIO1 (B7) and RADIO2 (B9) buttons indicate receive focus. Headphone
switching is based on the configuration options and application control signals described later.

control only and do not control transmit focus (select active transmitter).
B10-B13 – FUNCTIONS F1-F4: Store/Recall four independent hardware configurations or "scenarios."
Pressing one of these buttons recalls a configuration. Pressing and holding a button stores the
current state of MK2R/MK2R+ in that "memory." A light will illuminate adjacent to the active

B14 – RADIO1 TRANSMIT FOCUS: Selects transmission on RADIO1 and disables automatic control of
transmit focus if it was enabled.
B15 – RADIO2 TRANSMIT FOCUS: Selects transmission on RADIO2 and disables automatic control of
