As the EM horn ages, the voltage (EMVolts) required increases over time. If the
EM voltage must always be set at or near –3000 VDC to complete Autotune,
with no other probable cause, it may need to be replaced. Check your tune
charts for gradual degradation, which indicates wearing out. Select View
Tunes from the Checkout menu in the Instrument Control view to see the tune
charts. Sudden changes usually indicate a different type of problem.
