Your special BatPhone doesn't have to sound like an ordinary phone.
	
Instead of a regular ring or a basic buzz, it can be equipped with an exciting attention-getting bat-like electronic ring signal. It's powerful enough to wake up Alfred.
	
This price is in addition to the price of the phone, not for an electronic signal purchased alone.
	
The bell will be removed when the electronic signal is installed for you. 
	
The signal is pre-set to a "medium" volume level, but it can be easily adjusted from low to a LOUD SCREECH. (Photo is similar to actual device, but not exact.)
