[Nut-upsuser] Problem with starting nut

[Master Yoda]

Hello,

i just installed on Ubuntu 12.04 nut from their "Ubuntu Software Center"
and i configure ups.conf as:
[mustek]
driver  = blazer_ser
port = /dev/ttyS0
desc = "Mustek powermust 2000VA USB"

and here is # /lib/nut/blazer_ser -DDDDD -a mustek results:
http://pastebin.com/J47JrmrT
As i see all is ok here?

After that i try # /etc/init.d/nut start and got:
/etc/init.d/nut: 1: /etc/nut/nut.conf: MODE: not found
 * nut disabled, please adjust the configuration to your needs
 * Then set MODE to a suitable value in /etc/nut/nut.conf to enable it


I cannot find what kind of mode he talking about, i put in nut.conf "MODE =
standalone"



Where i am wrong?
please help, thank you!
