What Does This Do?
1.  Mode Button - Selects the display mode (Normal or Strobe) for the 
Tuning LED Array. The modes are labeled below the last two LEDs of 
the Tuning  LED Array.
2.  Input - Connect your instrument here. This jack enables battery 
power to the pedal when connected. To prolong battery life, 
disconnect the cable from the Input jack when not in use. If the 
optional Harman power supply is used, cables can remain connected.
3.  Foot Switch Release Pins - These two pins are spring loaded 
hinges that hold the Foot Switch in place. See page 14 for information 
on accessing and changing the battery.
4.  Foot Switch - Turns the Tuner on and off.
