power of the power distributor on. When AC power is supplied, the POWER LED lights up.
2. Turn the source device on and check the broadcasting output is normal.
3. After checking the normal broadcasting, test the emergency broadcasting to check if the SEG-1404 switches
the broadcasting correctly. (The emergency audio signal is forwarded to all outputs 1~4.)
4. When the test is finished, make sure that the AC power voltage and pins of the EMERGENCY contact closure
are in operable condition.
