## UPDATE METHODS:

The PC3K can be updated by one of two methods:

- Method (a): direct USB connection to computer
  requires: Computer (Mac or PC) with USB port + USB cable. Please remove any thumb drive connected to the PC3K during the update.
- Method (b): USB storage device
  requires: Computer (Mac or PC) with USB port + USB Storage device - such as a thumb drive.

  Notes on updating via thumb-drive:

  *Thumb drives drawing 100 mA or less are recommended.
  *We advise using the smallest capacity thumb drive you have available.
  *After plugging the drive into the PC3K, wait for about a 30 seconds before proceeding with the install.
  *The OS update .KUF file must be located in the drive's root (top) directory, not within any sub-folders. An "Error -2" message will be displayed if this is not the case.
  *After copying the .KUF file to the thumb drive, be sure to to Eject/Unmount the Thumb Drive from your computer before physically unplugging it from the computer's USB port.

## .KUF FILES:

This update kit includes FOUR (4) different update files (.KUF), one for each possible configuration of optional ROM expansions. Via either update method, you will only be installing ONE (1) of the included .KUF update files. Choose the ONE(1) install file that matches your PC3Ks configuration:

> My PC3K Has: | File to Install
> --- | ---
> NO ROM EXPANSIONS | P3K245.KUF
> ONLY KORE 64 | P3K245K.KUF
> ONLY GERMAN D GRAND EXP | P3K245G.KUF
> BOTH GERMAN D GRAND EXP + KORE 64 | P3K245GK.KUF

Note: if NOT installing the German D Grand or KORE 64 at this time, but obtain either at some later point, you will then need to reinstall this update, using the corresponding update file.

## UPDATE PROCEDURE:

### !! Before updating, be sure to back up any custom programming as user memory will be erased in the process!!

If unfamiliar with the process, please see the following link (or your manual) for details: "Backing Up the Entire User Memory"

Note: if you have the "K2661 ROM Compatibility File" installed it too will be erased in the update process and need to be reloaded afterwards. (If you are installing the German D Grand, this does not apply.)

1. Choose Update Method:

   (a) If updating via USB-to-Computer connection, connect USB cable between PC3K "Computer" USB port and any available USB port on your PC/Mac.

   -OR-

At that time you will be instructed to copy (drag and drop) the .KUF update file to this temporary removable disk. Be sure to copy the ONE appropriate file when prompted. For now, proceed.

(b) If updating via USB storage device: copy the ONE appropriate .KUF to the root directory of the device using the method specific to your computer system.

    With NO ROM EXPANSION installed:

                           Object Ver  : 2.45.3
                           O/S Version : 2.41.24383

    With only KORE 64 installed:

                           Object Ver  : 2.46.2
                           O/S Version : 2.41.24383
