Download the correct update file to anywhere on your PC where you'll find it again. (I use a folder in my Downloads Folder, called Pentax) When you install the update, it will extract two files, a .bin file and a readme.txt file. That's the readme file which has all the instructions as how to install to your camera. The .bin file is the firmware update file which needs to go in the root folder on your SD card.
I assume you have an SD card reader, if not, you can use your camera tethered to the computer as a card reader.
If you do not feel confident doing this, then take your camera to a good camera shop who will be glad to do it for you for a fee.
Remember to ensure you have a good, formatted SD card. (Formatted in the camera) Make double sure you have a fully charged battery in the camera when installing the firmware. Do not under any circumstances turn the camera off while it's installing the firmware update.
