Clearing the Paperless Tape:
The Paperless Tape is cleared upon:
1) a double press of o;
2) a Clear All ( C x );
3) the start of a new string of equations
after exiting the tape function (starting
with a number, not an operator); or
4) turning the unit off.
Rate Function
The rate function is used to multiply a
numerical or time value by a per-unit
rate. This is primarily used for finding
costs based on a per-unit time price
structure. You may clear the value by
performing a “Clear All” (C x) or
replace it with another value.
Entering a unitless value, then pressing
s R will permanently store that
value as the rate. When entering a
math string, R pressed after a unit-
less value will override the previous
rate. For example, if you enter
2 • 5
H x 1 0 R
TimeMaster II
uses
10 as the rate instead of the stored
value.
Note: Trying to enter a time value into
the rate key causes an error.
