LCD, need A4 Board Manual?

[rich251076]

I just bought what I think is an Angel LCD? with an A4 board from Ebay:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7169480508&rd=1&sspagename=STRK%3AMEWN%3AIT&rd=1

I can find the manual for the LCD on the WDP site, but no manual for the A4 board.

The A4 marker manual does not seem to apply to the board since the board has fewer buttons?

Can anyone point me to a manual on the A4 board?

I have a few other questions regarding the LCD as this is my first angel...

I would like to finally confirm which model this gun and the year it was made, there is a serial etched inside the gun, if this helps: 14731 ?

I would like to know how to confirm this gun has the A4 board, is there a way to determine this through the LCD menu?

What is the operating pressure of this gun?

Could you tell me if I need regulator on my tank with this gun or is the second stage reg in the front grip enough?

If I need a tank reg what pressure should it be set to deliver?

What pressure does the reg in the grip bring the PSI down to?

Would this gun use a high pressure tank or a low pressure tank?

Could you tell me what kind of charger this model takes and where I can get one, I didn’t get one with the gun?

Can anyone point me to some links on servicing the LCD myself?

Thanks Rich
