How turn off ship's sirene - alarm

[mazyst]

In first sentence - I want apologise for my English.
I Play Silent Hunter IV v. 1.5.
A few days ago I discovered the pleasure of playing watercraft - surface ships like Montana and Iowa.
Obviously, I received a few hits from opponents - and start alarm signaling, siren sounded.
Unfortunately she is constantly working.
How to turn it off?
I do not know about programming, but maybe something in the configuration files can be changed?
Please help me.
