Tests were done with a Futaba 9ZHP and have not been verified to be identical with the newer versions. If you can verify this for us we would be happy to hear from you.
When accessing menus in the 9Z, remember the following:
- Menu Modes 1 & 2 are not applicable, use only Menu Mode 3
- You can press "PRE" and "NXT" at any time to scroll among screens
9Z Service Menu Mode 1
This Menu Mode does not work with the 9Z. Booting into Menu Mode 1 makes the radio think there is a CAMPac present and it asks to initialize it. Pressing "Yes" will cause the radio to think it's initializing a CAMPac when in fact it's doing nothing.
9Z Service Menu Mode 2
The radio will boot normally, as if there is no memory module present.
9Z Service Menu Mode 3
The radio will boot into a service menu that lets you select between "A" and "B". The two menus are shown separately below.
9Z Service Menu Mode 3A
This screen seems to give an identification number of some sort as well as the total run-time of the radio.
Here you can set the switch types for each of the toggle switches. The options are 2-position, 3-position, or "M". The "M" type means momentary and refers to a 2-position switch that normally stays at its home position like the trainer switch (switch H).
9Z Service Menu Mode 3B
This seems to be a calibration for switch A. With the switch up press "SET", then with the switch down press "SET". The boxes will turn dark.
Sets the center points for the TX sticks. Move the sticks to their center points and press "SET". The four boxes should turn dark.
Sets the end points for the sticks, slides, and knobs. You can calibrate the sticks/knobs/slides all at once, or you can calibrate any number of them at a time. Move the sticks fully down and right, the knobs fully clockwise, and the slides fully down. Press the "SET" button to set the endpoints. Succesfully calibrated sicks/knobs/slides will have a darkened box.
Same as the last screen but sticks should be moved fully up and to the left, knobs fully counter-clockwise, and slides fully up.
Voltage calibration. We're not sure how it works yet.
Lets you test all the toggle switches. As you flip switches back and forth the boxes will turn black.
Trim button test. Move each trim back and forth and the top boxes will turn black. The bottom line of boxes is for fast trim - they will turn black when you push the trim fully left/right/up/down.
Another voltage calibration screen?
RPM calibration? Although it doesn't make sense to have to calibrate it - it isn't an analog measurement.
Seems to show the status of the CAMPac port and possibly the buddy box jack on the back of the radio. For example, when the 256K module is removed from the radio one of the bits changes.
Screen test blinks the entire display on and off so you can check for dead pixels.
Button test. As you press each input button (A through R) the box will say "OK".
After all the buttons have been pressed this screen will appear. Selecting "NXT" will cause the radio to shut off.
