1.3.2 The touch panel (switch) of the Display does
not respond to touch but another area
responds instead (The panel responds when
nothing is touched)
Does this phenomenon occur with all switches?
Cause
If the switches do not respond properly even after the self-diagnosis in offline mode, the
GP unit may be faulty.
Solution
• When all switches do not respond properly
When the same phenomenon occurs with all switches, try the solution for the next sec-
tion “Can the GP enter offline mode?”
• When only specific switches do not respond properly
(1) Select the [Check Touch Panel] option and check that the touched area lights up properly.
For the checking procedure, see the following section.
)
“2.8.1 Checking whether the Display is operating properly n Touch Panel” (page 2-48)
(2) Check the settings and address of the problematic switches. If the phenomenon continues
after the check, the GP unit may be faulty. Please contact your local GP distributor.
