Anybody know how to get to the "hidden menu" to change the low voltage alarm.
I want to change the voltage for li-po's.
Thanks

if you can translate it from a 783 to the 9303.............


1. Enter System Mode (Model Selection Mode)
Press and hold the UP and DN keys simultaneously and power on the transmitter.
It does not matter which model is selected - its settings will not be altered.
Using the UP key, scroll through the functions until RSET is displayed.

2. Enter Service Mode
Set the GEAR switch to the rear position.
Now the tricky bit-
Flip the GEAR switch to the front position then press the DATA+ key.
Flip the GEAR switch to the rear position then press the DATA - key.
Repeat this fairly quickly until there is a BEEP (another 3 times should do it).
If there is no BEEP after 4 completed cycles it failed, start again.
If there is a BEEP the screen changes to INTL.
You are now in the Service menu.

Make sure that THOTTLE HOLD is the rear right switch on top of set. ( IT IS THE SMALL "SLIDER" ON THE RT SIDE OF THE RADIO)

1 Pull Throttle Hold switch into the forward position.

2 Power the set on whilst ENT (Front Panel is pressed)

3 Rotate until Trim Step is highlighted.

4 Activate on Trim Step, rotate to AILE

5 Switch AILE D/R down, press roller activator, switch AILE D/R up, press roller activator.

6 Repeat sequences 4 times and on the 5th, access is granted to the EM.

From here, SW test allows you to test each switch and micro switch.

The next menu item is Hard. Con, on rotating the selector bar it becomes obvious what can be changed by “soft” selection. Where the highlighter does not move to indicates that this is a hard connection on the PCB, but in conjunction with the table this can be modified accordingly.

Next item is Stick Nut. Centralize all sticks and side trimmers, press CLR followed by STO. This then stores all the offsets for the sticks.

Next is Stick Ga., moving all sticks and side trimmers to max & min positions finalizes the stick calibration.

Moving the selector across to the right allows for setting front panel voltage, (Lithium voltage will display as 0.0V) and at what voltage the alarm will activate for low battery.

To exit this Engineering, rotate to EXIT then select Restart

Thanks, that works.
Took 9 switch/press combinations.
CAUTION USE WITH CARE-looks like you can really screw up your radio.

all the prior versions I've tinkered with have a factory default reset, the 9303 should too.

Hey there ,
I'm about to pull all the hair on my head trying to enter this secret menu. I have been trying for about 4 hours and my patience is wearing off. Would somenone please clarify this "entering the engineering menu" thing for 9303 mode 1 tx.
I'd be grateful for any help, this radio issue is at a point where I may end up quitting the hobby.

thanks in advance for help,
