[P/NP] ................... Switches between PRINT and NON-PRINT mode. At reset, NON-PRINT mode is
[RND] ................... Switches between round-up, round-off and half-adjust. At reset, half-adjust is set.
[DEC].................... Switches the decimal point. At reset, floating point (F) is set. Switches the mode in
[TM/S].................. Sets time and date. Pressing the [TM/S] key in clock/date display mode sets time
[RT/S]................... If pressed after key entry, sets the conversion rate.
[A ® B] ................. When the [TIME] key is on, moves the cursor to the right as the [>] key.

When the [CAL] key is on, executes rate conversion as the [A ® B] key.
Example of [A ® B] key operation when rate value is 130:
Pressing the < [A ® B] key after clearing display calls the rate value.
When the [CAL] key is on, executes rate conversion as [B ® A] key.
Example of [B ® A] key operation when rate value is 130:
Pressing the < [B ® A] key after clearing display calls the rate value.
