The PC power was dropped during unit scanning. What happens to the data scanned up to the point? Is
data integrity maintained?
4.
The scanned data is saved when scanning is completed and the [OK] button is pressed.
When the power was dropped before this, the data scanned up to that point is lost. Restart scanning from
the beginning.
Can the U10 USB Network Interface used with the System Controller Lite also be used with service tools
and other software?
5.
The adaptor can also be used with service tools. However, one adaptor cannot be used simultaneously by
the System Controller Lite and service tools.
What is the difference Secure Reg enable and disable at Unit Registration?
Secure Reg. enable is a mode which stops operation of all the units and confirms scanning for unit recog-
nition. Secure Reg. disable is a mode which performs scanning in parallel without stopping operation of
the units.
Since scanning is an important function for recognition of the units to be managed by the System Control-
6.
ler Lite, it is recommended that, as a rule, it be performed by enabling Secure Reg. If unavoidable, disable
Secure Reg only when scanning must be performed without stopping operation of the units. In any case,
whether or not units were recognized correctly must be confirmed after scanning. However, when scan-
ning was performed with Secure Reg disabled, re-scanning may be necessary due to unit recognition
misses.
Scanning was performed, but all the units were not recognized. What should I do?
When work is performed normally and scanning is performed after confirmation and units are not recog-
nized, first check whether or not the power of the unrecognized units is turned off.
7.
Other causes may be:
•Unit trouble
•Deterioration of the work state
In any case, contact the relevant dealer.

indoor unit R/C group. Refer to the service manual and perform setting correctly.
