4. Engineering states E0-E3 contain 16 hexadecimal numbers representing eight bit binary
words stored in the EEPROM. Interpretation of the binary words relating to the first two
screens indicate the options programmed into the pager.
5. To establish the programmed options convert each hex digit to its four bit binary number
using Table 2. Align these groups of binary numbers to their respective positions in Table 3
and extract the programmed options as shown in Table 4. See below for sample engineering
mode displays of the first two screens.
