HP 35s Scientific Calculator - Manual (Page 166)

11-8 Base Conversions and Arithmetic and Logic
In BIN/OCT/HEX, If a number entered in decimal base is outside the range given
above, then it produces the message  . Any operation using  
causes an overflow condition, which substitutes the largest positive or negative
number possible for the too-big number.
Windows for Long Binary Numbers
The longest binary number can have 36 digits. Each 14–digit display of a long
number is called a window.
When a binary number is larger than the 14 digits, the

or annunciator (or
both) appears, indicating in which direction the additional digits lie. Press the
indicated key (
Ö or Õ ) to view the obscured window.
Using base in program and equations
Equations and program are affected by the base setting and binary, octal and
hexadecimal numbers can be entered in equation and in program as well as when
the calculator prompts for a variable. Results will be displayed according to the
current base.
