The buffer battery may only be replaced by a qualified electrician.
6.3 Replacing the terminal
From version 2.9 of the B-COMM Java communication software, the terminal can, if 
required, be easily replaced by another one. B-COMM manages the configuration 
of all registered devices. The current parameters of all terminals are interrogated 
and backed up once a day. 
Conditions:
• Can only be replaced by devices with identical hardware.
• Special replacement terminal required. The contains a sop.ini licence file with the 
parameter "Replacement=true".
• The network parameters DHCP and "DNS Configuration from DHCP" must be 
active (delivery state).
Procedure
1. Replace the old terminal with the replacement terminal.
2. After switching on the replacement terminal, the serial number of the replaced 
terminal must first be entered.
3. A connection is automatically established and B-COMM Java then transfers a 
modified licence file and all the existing applicable parameters to the 
replacement terminal.
4. The replacement terminal is restarted automatically and is then ready to use.
5. The master records and time profiles can now be sent to the terminal.
