Using the Internal Memory
Internal memory lets you continue saving results if you run
out of memory card space. Internal memory is in the
mainframe (rather than in the module) and is retained
when you turn off the tester or remove the battery pack.
See Chapter 9 for more information on the internal
memory.
Using an External Keyboard
The keyboard jack on the right side of the tester accepts a
6-pin mini DIN (PS/2) plug. The tester accepts only the
characters available on its text editing screen. Figure 1-23
shows which keys you can use on the keyboard.
Note
You cannot use an external keyboard to enter
international characters.
The OptiFiber Product Manuals CD includes a full-size
function key reference diagram that you can print, cut out,
and attach to the keyboard.
