From this document <>:

"If the POWER switch is turned on, while OPER/STBY switch is at OPER(operate) position, the orange OPER lamp will blink, and you will need to reset the OPER switch to enter into operation mode. “PSE STBY OPERSW is displayed at this time."

Manual says something similar.  So, if you are sure the OPER/STBY switch is in the STBY position when you power up the amplifier, and you're sure that nothing is plugged into the SEND jack by mistake (like an ALC cable), and the amp. displays that message every time you power up, then perhaps the OPER/STBY switch is defective or wired backwards.

    Hi Folks,
    I'm having an issue with the THP HL-2.5Kf and I have a couple of
    questions. I do have the 1.5C firmware. I have it hooked up to a
    K3. The
    amp is set to Yaesu band data. I know the amp used to work with a K3.
    The amp never seems to leave "PSE STBY OPERSW!" on the display
    after the
    amp is powered up.

    What causes the "PSE STBY OPERSW!" ?? Manual says power cycle the
    amp to
    reset it. I don't see any other answers... I have even pulled the
    and allowed it to sit...

    It does not seem to matter if the radio is hooked up amp. Does not
    matter if the the amp is in auto or manual mode. It also does not
    if it is in operate or standby.  I wanted to check both fuses... One
    fuse I can't seem to open  and one of the fuses is fine, but the amp
    powers up. My guess is that it is OK (bad thought?).

    Any thoughts? Really could use some help with this!!
