3310 "AUTO TURN OFF"......
 
The solution for 3310 auto turn off problem can be solved by lowering the value of R301 resistor network near the MAD2....This envolves changing the value from 2.2K ohms to 100 ohms of the network..

But since its little bit difficult to remove this said resistor..What I did is to add in parallel one 120 ohms resistor on one side of the network nearer the MAD2, thereby lowering also its value....And just leave the other resistor on the network on its original value...

So far the solution also works good for me!!And for those who can't locate the said resistor network just mail me..

Best regards,

neb

neb pls email me the location of the mad2 where u placed the resistor [email protected]

Hi emix,

I'm sending you an image file so that you can easily locate R301 (2)2.2k ohms resistor network...Check your mail!

Regards,

neb

cud u send me the location too neb? :) thanx!

ambot 06-22-2001 15:20

hi trafix, i found it (R301 2.2Kohms).. its just beside the N200 (corner side)...

eureka8888 06-22-2001 15:35

hi neb can u also mail it to me, and how to connect in pararell the other resistor(shemeatic), thanks

thanks neb i have a question for you chech email

rothmanns 06-24-2001 20:33

neb tnx for the mail.. :) but still cant figure it out... where can io buy the parts to solder there???

GsmSolution 06-24-2001 22:04

Hi
Can anybody send to me.
Thanks. :-) :)

neb 06-25-2001 00:19

If you have a hard time following the procedure, I suggest you'll try HAMS solution, the removal of L511 chip inductor as per my test it can also solve auto turn off/hanging problem, and its easier compared to lowering the value of resistor network r301.

neb
