Need Help!- Meldas 300 Data Protecting

[cncsooner]

I have a MHI lathe that the battery went dead and im tring to get it going again. I have all the steps to do so but when i get to the format part in the data I/O erase screen it doesn't let me even curser over to type in format. It gives me a data protecting alarm. I have found edit lock C and B both are off.
I have been told that edit lock A is on witch should be a key switch but there isn't one on the machine. I have also talked to Mit. and they have told me I can change Y238 bit to 0 and that should do it but it won't (or I don't know the proper way to change it) let me do that either. please help

You can change Y238 to 0 through the PLC I/F page. Under DEVICE type the address (Y238), under DATA type 0, and under MODE type 2 and then try to format. Do not power off and on before formatting as this will change Y238 back to a 1.

Machine parameter selection

Press the {PLC-I/F} menu key on the diagnosis {DIAG} menu

Set 1001 into DEVICE {}
Leaves DATA {} blank
Set M into MODE {}

Press the {INPUT} key

THIS SHOULD DISABLE THE DATA PROTECTING

To return to the user parameter display, either switch the power ON and then OFF once or proceed with the following operation:

Set 1001 into DEVICE {}
Set U into MODE {}

Press the {INPUT} key

DATA PROTECT KEY 1
M31OM,L : Y1B8 Y338
M320, 330, 335 : Y238
M330HL : Y238

DATA PROTECT KEY 2
M31OM, L : Y1B9 Y339
M320, 330, 335 : Y239
KEY2 M330HL : Y239

DATA PROTECT KEY 3
M31OM,L : YIBA Y33A
M320, 330, 335 : Y23A
M330HL : Y23A

So make sure to take care of all three signals. Also, I think they should all be set to "1" for not protected, and "0" for protected. Cheers.
