CALCULATING TAX /
计算税率
• To perform a tax calculation, first it is absolutely necessary to set and check the tax rate. (The initial
tax rate is 0.)
A tax rate can be set (or changed) with a number containing up to four digits. (Decimal point is not
regarded as a digit.)
The set tax rate is retained until it is changed. However, the set tax rate may be changed or lost if the
battery is consumed largely.
