Input Battery Data
As the cameras battery voltage drops, the three shaded LCD battery
symbol inserts drop out to reveal an empty battery. A short time after the
third segment drops out, a flashing battery warning appears on the LCD
screen. These four battery voltage thresholds are inserted as data levels
at page d.
The data reference number from above is in hexadecimal. You must
convert that hexadecimal number to decimal, then add 5. Convert this
new decimal number back to hexadecimal and put that number into Ad-
dress 91.
1. Use the hexadecimal to decimal Conversion Table in the service manual
to change the reference data number at Page d Address 91 to a deci-
mal number. In the example given, hex number AE is looked up in the
chart as decimal 174. The conversion chart is under Data Process in
the table of contents.
2. In a similar process, add decimal number 23 instead of 5, convert it
back to hex and change the data in Page d, Address 92.
3. In a similar process, add decimal number 44 instead of 5, convert it
back to hex and change the data in Page d, Address 93.
4. In a similar process, add decimal number 55 instead of 5, convert it
back to hex and change the data in Page d, Address 94.
