10. OPERATION After completing all connections, turn on the power switch, and check to confirm that the power indicator lights. Note When the heat sink temperature exceeds 85 °C (185 °F), the protection circuit begins to operate to disconnect the output from the circuit. The disconnected output is automatically restored as soon as the temperature returns to the normal operating range. -
Page 16: Volume Setting
13. VOLUME SETTING Output levels are adjustable with individual volume controls. For music play or announcement, adjust the corresponding volume control so that the signal indicator lights intermittently. Note that the sound quality is downgraded when the peak indicator remains lit. 14. -
