necessary, to see additional currencies ( see table 4–2 ).
2. Press a menu key to select currency #1.
3. Press a menu key to select currency #2. RATE is automatically reset to

exchange rate is usually the easier way to enter a correct rate, since

! Store the exchange rate by keying in the value and pressing (see
“Storing an Exchange Rate” on page 58).
