KeyPad service manual
Rev.1.1
7.2 Power LED malfunction
If the power LED is not correctly functioning and the section 1 has been fully
verified:
Verify the battery and the socket integrity (see figure 23 for location):
Part must be replaced and the preprogrammed setup must be
reentered if the battery is bad.
7.3 LCD Display problem
If the section 1 has been fully investigated and the system is always returning to
the default setup (EN language, default heating block type etc.), then replace the
on board battery. You can check the battery by turning off the instrument off for
about 5 min. Turn it ON and see if the info set is still unchanged (system
language, block temp set and time). The default values are: Jr, English, 25C
and 999min.
