INFO
Stopwatch
The stopwatch shows the hours (h), minutes (‘), seconds (‘’) and
hundredths of a second. The stopwatch continues to run even
when you leave INFO. When the power is interrupted (switch-off),
POSITIP resets the stopwatch to zero.
Pocket calculator
The pocket calculator functions are spread over three soft key
rows :
• Basic arithmetic (first soft key row)
• Trigonometry (second row)
• Square root, x

press the HELP key.

rectly into a program as a nominal position — without having to
