blinks will equal the 2nd digit. If there are two or
more codes, there will be a 2.5 second pause bet-
ween each code.
• After all the codes have been output, there will be
a 4.5 second pause and they will all be repeated as
long as the terminals TE1 and E1 of the check con-
nector are connected.

tion will begin from the smaller value and continue to the
