The reason for being junk is the power switch.
When the rotary switch is turned from off to on, the power turns on and it first goes into camera mode.
To switch to playback mode, you need to turn the rotary switch further, but after turning it all the way and the mode switches,
if you release your finger as the spring pushes it back, the message "Processing, please do not remove the power" is displayed and
it automatically returns to camera mode.
If you keep your finger on the innermost part for a while and slowly release it, it often goes into playback mode correctly.
It's probably due to the deterioration of the contacts over time, but I haven't disassembled it, so I'm not sure. (It feels like it could be restored by cleaning the contacts)

I have confirmed the functionality of various physical switches, optical system, recording settings, and playback settings.
There are no sunken or sticky switches, and the jog shuttle also works correctly.
I also took some test shots for the listing, and was able to record continuously for over 3 hours.
The HDD is also running quietly.

The exterior has some scratches, but they are not too bad.
The lens is clean with no clouding or dust.
No peeling of the coating on the LCD display.
The screws are clean with no corrosion.
The faux leather on the holder is clean with no cuts or scratches.

The charger is the genuine CA-570, but the power cable may be a generic one as it doesn't have the Canon imprint.

The battery can be used, but I haven't measured its performance. Please consider it as a bonus.

The items included are the main unit and charger only.
No returns or exchanges.

Other features: Junk, with battery, with charger
