Precautions for Safe Use • 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. • Do not connect a USB connector to any device that is not applicable. • Changing the current value or the set value. • 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. • Dispose of the Units and batteries according to local ordinances as they apply. • Pressing the PT’s reset switch. • 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 dispose the Units together with general waste at waste yards. When disposing them, follow the related local ordinances or rules.
• Do not use benzene, paint thinner, or other volatile solvents, and do not use chemically treated cloths. • 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 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.
