Before the procedures in this chapter can be carried out the connection to external cir-
cuitry must have been checked which ensures that the installation was made correctly.
The user must energise the power supply to the terminal to start it up. This could be
done in number of ways, from energising a whole cubicle to energising a single termi-
nal. The user should reconfigure the terminal to activate the hardware modules in order
to enable the self supervision function detect eventual hardware errors. Then the termi-
nal time must be set. The self supervision function should also be checked to verify that
the terminal unit operates properly. The user could also check the software version, the
terminals serial number and the installed modules and their ordering number to ensure
that the terminal is according to delivery and ordering specifications.
