How do you retrieve the BIT Fault codes from a LaserRef1?

“BIT” button leads to 3 pages :
Bit 2- Current Status
Bit 3 – Last Flight
Bit 4 – All History

Now: lets look at the 270 word

One example is 0082 2800

Note the first two digits are 00 and the last two are 00.  they are unused digits in this scheme.

This Work sheet might help with the decode.

And the 270 Word definition, or the 350 word definition might help.
