## Discrepancy

EMERGENCY LIGHTING: WHEN BATTERY SWITCHES ARE OFF AND EMER LIGHT SWITCH IS ON, THE GALLEY LIGHT, THE LIGHT BETWEEN SEATS 1 AND 3, LIGHT BETWEEN SESTS 5 AND 7, AISLE LIGHTS, LEFT EGRESS LIGHT AND MAIN CABIN DOOR EXIT SIGN ARE ALL INOP. THEN: WHEN BATTERIES ARE ON, EMER LIGHTS IN ARM AND PAX SAFETY SWITCH ON....ONLY THE NO SMOKING LIGHT ILLUMINATES. ALL OTHER REQUIRED LIGHTS ARE INOP.
