• When changing the password with the screen, do not reset or turn OFF the power supply until writing
is finished. Failure to save the password may cause the screen to fail to function.
• When using an equipment monitor, confirm the safety of the system before carrying out the following operations:
• Changing monitor data.
• Changing operation mode.
• Forced set/reset.
• Changing the current value or the set value.
• Do not connect a USB connector to any device that is not applicable.
• When connecting the equipment with the USB HOST connector, make sure the supply equipment's
current capacity is below 150mA before using it. The DC+5V voltage output of the NB Unit is
+5V±5%, and the maximum current is 150mA.
• Before connecting a USB connector to a device, make sure that the device is free of damage.
• Commercially available and the recommended USB HUBs are different from the general
specifications of the NB Unit. The unit may not function well in an environment subject to noise, static
electricity. Therefore, when using a USB HUB, employ sufficient noise and static electricity insulation
measures, or install it at a site free of noise or static electricity.
• While uploading or downloading screen data or system programs, do not perform the following
operations that may corrupt the screen data or the system program:
• Turning OFF the power supply of the NB Unit.
• Pressing the PT's reset switch.
• Dispose of the Units and batteries according to local ordinances as they apply.
• Do not dispose the product into a fire. Doing so may cause the damage with the battery or electronic components.
• Do not apply an impact with the lithium cell, charge it, dispose it into a fire, or heat it. Doing either of
them may cause an ignition or a bursting.
• When exporting products with lithium primary batteries containing perchlorate at 6ppb or above to or
delivering them through California, USA, the following precautionary measures have to be publicized.
Perchlorate material - applicable through special processing. Refer to
http://www.dtsc.ca.gov/hazardouswaste/perchlorate.
NB-Series products contain lithium primary batteries. When exporting products containing this kind of
batteries to or delivering them through California, USA, label all the product packages as well as the
appropriate delivery packages.
• Do not use benzene, paint thinner, or other volatile solvents, and do not use chemically treated cloths.
• Do not dispose the Units together with general waste at waste yards. When disposing them, follow
the related local ordinances or rules.
• Cannot replace the backlight lamp inside the NB Unit.
• Deterioration over time can cause the touch points to move. Calibrate the touch panel periodically.
• Water and oil resistance will be lost if the front sheet is torn or is peeling off. Do not use the Unit, if the
front sheet is torn or is peeling off.
• The rubber packing will deteriorate, shrink, or harden depending on the operating environment.
Inspect the rubber packing periodically.
• The communication cables of the COM1 and COM2 connectors are not interchangeable. Confirm the
pins of the ports before carrying out communications. (NB3Q-TWB only has COM1.)
• Periodically check the installation conditions in applications where the PT is subject to contact with oil or water.
• Do not perform the following operations during the communication of the USB memory:
• Turning off the power supply of the NB Unit.
• Pressing the Reset button on the NB Unit.
• Removing the USB memory.
• Do not use the USB memory in the environment subject to strong vibration.
