Vertek/XTC SCORPION 2330 사용자 설명서

Sessions are timed events used in coin mode which can change certain aspects of 
Scorpions behaviour. There are four types of sessions available:

Background Play
A background play session causes Scorpion to play random songs from  
preselected categories at set times. These songs will be cancelled automatically 
as soon as a user chooses a song. Background sessions can optionally play at 
reduced volume and without showing full screen video.

Category Change
Allows you to specify which categories are available to users of the  jukebox 
without making any other operational changes.

Bonus Play
Bonus play sessions give the users extra free credit such as 2 for 1 or 3 for 1.

Free Play
Free play sessions switch off the coin validator and allow song selection without 
requiring money.

Free play and bonus play sessions are often used during happy hours in bars.
Creating all four types of sessions is carried out using the same procedure:

Start by opening the Session Management window which is item 660 in the 
administration section.
