19.3 Check tracking master down 
19.3.1   In case of master down 
 
Using shared check tracking and happened check tracking master down (E105 Can 
not access check tracking server), please [Retry] first instead of [Remove]. On the 
other hand, master downs frequently, make sure the network configuration and 
communication hub to stabilize. Remove is the final operation. 
 
Once remove the master, the satellite terminal goes to standalone mode. NEW/OLD 
and HOLD operation check data store inside satellite terminal and never access 
master data. Standalone mode will be kept until restart cash register application.   
 
A.Master down when NEW/OLD operation. 
  This means could not get check data from master terminal. 
 If it does not recover with retry key, use remove key to disconnect network, 
check network and restart cash register to reconnect master. 
 
B.Master down when HOLD operation. 
  This means could not put check data to master terminal. 
 Use retry key to reconnect master. But if it could not connect master then 
remove master and goes to standalone mode. Hold check data will be stored 
inside satellite terminal. 
 Do not use same check data of master as satellite. Finally finalize the check 
data at satellite terminal in case of stand alone mode. Also do not restart cash 
register application. 
 Check data that soterd before master down error, please use the data on 
master terminal. Satellite terminal can not get the data from master.   
 Check data that created on satellite terminal with standalone mode, please 
finalize the data on satellite terminal. Also do not restart cash register.   
 
Cash register app Ver4.3.3 shows [Network Error] message top-right on screen 
when standalone mode. This means check data will be stored inside satellite 
terminal and never access master. After restart cash register the message will be 
cleard and reconnect master.
