  13. DIRECT BATT. DIRECT BATT. Direct Battery Switch - Light Logic The DIRECT BATTERY pushbutton brings power to certain components directly from the battery. The Direct Battery pushbutton MUST be depressed to the “ON” position to activate the Transponder and Nf indicator. Normally, both the EXT PWR / BAT and the DIRECT BATTERY pushbuttons are engaged. When both are engaged, the DIRECT BATTERY pushbutton will not beilluminated. If onlythe DIRECT BATTERY pushbutton is depressed to the “ON” position, then the lights are illuminated. 7.13
