Remote Power On/Off

[Carl Ferguson]

I frequently operate remote.  I am new to the K3.

I interpret the manual to say to

To turn the radio back on after my control program sends a PS0; command to
power off

   - turn on the DC power supply (this DC supply operates equipment in
   addition to the K3 and must be turned off when the station is shutdown)
   - ground ACC Pin 8

To turn the radio off

   - send the PS0; command
   - open ACC Pin 8
   - turn off the DC power supply

I infer from this sequence that pressing the Power button to turn on the K3
effectively grounds ACC pin 8.

Conversely, pressing the Power button to turn off the K3, opens ACC Pin 8.

Is this correct?

Thank you.

Partly correct. Pressing the power button to turn off initiates a shutdown
procedure. Pin 8 is only grounded momentarily when you power on and does
not stay grounded while powered up. Powering down by simply removing power
is not recommended.
