1. Please follow these steps in order. If the power is interrupted, restart from step 1.

   BE SURE THAT ALL OTHER PROGRAMS ON YOUR COMPUTER ARE CLOSED. SET YOUR SCREEN SAVER TO "NONE". DO NOT ATTEMPT TO USE YOUR COMPUTER WHILE THIS UPGRADE IS UNDERWAY.

2. The power to the control box should be off. If not, turn if off.
3. Be sure that the keypad and power cables are connected to the GTO control box and locked in place. The motor cables do not need to be attached.
4. Place the keypad on a solid surface and press any three buttons (except stop) simultaneously and hold them down. We call this a "three-finger salute."
5. As you are holding these three keys, apply the power to the mount.
6. A new display will appear on the window of the keypad. At this point, release the three buttons. Then, press the West button to indicate YES for the next four windows. The last window requesting to Test Flash must be responded with NO by pressing the East button. This will erase the current program. These are the screen displays and the responses (note, the display says "FN=No", however you will press the "E" button):
   
   "Load defaults" - Choose Yes (West)
   "Are you sure" - Choose Yes (West)
   "Clear flash" - Choose Yes (West)
   "Are you sure" - Choose Yes (West)
   "Test flash" - Choose No (East)
7. Once you have completed the series of windows, the keypad will be placed in a ready-to-receive mode. A blank window with the blinking cursor in the upper left corner of the screen will indicate this.
8. Look back to the Keypad Upgrade Tool window on your PC. Press the Send Controller Code to Keypad button. The Keypad Loader Pre-Load Checklist will appear. Review and check all boxes, then press Continue.
9. A dialog box will appear requesting information about your current version of the keypad firmware. Answer the question.
10. You will hear a series of beeps from the keypad as uploading begins, but will get no audible feedback during the rest of the upload. From this point on, the update can take anywhere from 20 minutes to 35 minutes to update your keypad. Do not remove the power from the mount. Do not try to run any other application during this time. If you happen to check the task manager of your OS, it will state that the program is not responding, however it really is running properly, just slowly. Since the program must run through the control box into the keypad, it cannot run very fast. Make yourself a cup of tea.
