Power LED
• This indicator light is off when the HDS800 is off and no
external power source is connected to the DC power input.
• It is on and red when an external power source is present
at the DC power input and the HDS800 is off.
• It is on and green when the HDS800 is on, regardless of
whether it is powered from the internal battery or an
external power source.
• It is blinking red when the sleep mode has been enabled
and the receiver is currently running a session. With the
sleep mode enabled, the receiver is idle between any two
sessions, as if it were virtually turned off, and the power
LED is also turned off during this time.
