model, and stop the beeping used during automatic configuration. Should this procedure fail the
terminal can be manually configured by lifting the handset. Should this also fail the code *7 51 ext #

It is not possible to connect other devices to the same extension as a terminal.
Figure The 206 system can support up to six Executive Terminals and Standard Terminals
combined. The Executive/Standard Terminal will not function correctly on power fail extensions 11,
15 or 17 in the event of a power failure.

The 208 system can support up to ten Executive Terminals and Standard Terminals combined. The
Executive/Standard Terminal cannot be used on power fail extensions 11 or 12. It is also
recommended that extensions 21 and 23 do not have Terminals connected if the system uses
analogue exchange lines. A terminal will not function in the event of a power failure. Figure 4-4
shows the location of the power fail extensions.

Connecting terminals to 212 systems
The terminals share the same pair as ordinary SLT telephones. Terminals may not be connected in
parallel with any other devices. Terminals are not accepted on power fail extensions 11 or 12.
Terminals can be connected to power-fail extensions 25 and 27, though this is not recommended as
terminals will not function correctly should the power fail. After connecting a terminal it will beep
intermittently for about 8 seconds while it starts up. When the tones stop the terminal is ready for
use.
