Cheat mode:
Start the game with the +set cheats 1 +set ui_console 1 +set developer 1 command line parameter. Press ~ to display the console window. Note: Press [Right Alt] + ~ to display the console window if ~ alone does not make it appear.

Code - Result:

noclip - No Clipping Mode
fps 1 - Show FPS
dog - God Mode
wuss - All Weapons
fullheal - Full Health
notarget - Enemies Ignore You
maplist - Load Any Level (double-click map name)

Second Method
If you still cannot get the console to come up, you can actually bind the cheats to keys using the config file which does not require access to the console. Open your config file with Wordpad.exe (located by default in "My DocumentsEA GamesMedal of Honor Pacific Assaultconfigs"). The default file is "unnamedsoldier.cfg". Under the // Key Bindings section, simply change any of the bindings to the cheat codes. For example:

bind F1 "dog"
bind F2 "fullheal"

Then, while playing, each time you press F1, you will have god mode, F2 will give you full health, etc.
