<Selecting between Tax/EURO exchange functions>
Either of the Tax and Euro exchange functions can be selected by
changing the signal with the jumper cables on the KEY PWB.
<Backup of Tax/EURO exchange functions>
This machine is an AC type which retains Tax data (tax rates and
others) and EURO exchange data in memory only while the AC cord is
plugged in. Therefore, data in memory cannot be retained if the AC
cord is disconnected.
