Precautions on Usage
●
Installation
 Use your cellular phone or PHS one meter or more away from the product main unit in
operation, various transmission cables, and I/O cable. Otherwise, the system may cause
malfunction.
 When connecting the connectors and cables or installing the module to the base unit,
secure them with screws tightly.
Insufficient tightening may cause failure or malfunction due to vibrations.
●
Power wiring
 Keep the cables from other lines as much as possible. Especially, keep them away by
200mm or more from power lines.
 The terminal screw size is M3.5. As applicable crimp contacts, use the one for 3.5M
screws whose width is 7mm or less.
 Do not connect anything to the NC part.
●
Use of sample programs
 Use the sample programs described in the operation manual after performing an operation
check.
Make sure to perform an operation check before actual operation to avoid an accident due
to malfunction.
 Do not drop, bump, or apply strong shocks to the device or module. It may cause failure.
●
Battery replacement
 Battery replacement can be done while the unit is energized or not energized. When
replacing the battery while the unit is not energized, complete the replacement within 3
minutes. If the unit is left without a battery for a long time, the content of the RAM
memory may be lost.
 The Battery Normal LED (BAT) may illuminate during battery replacement. This is not an
error.
If the voltage decreases with the battery installed, the state will be detected normally and
the LED goes off.
 The battery voltage is not compatible with manganese batteries or alkaline batteries. Do
not mix them.
 Do not use a battery when 3 years or more have passed since the production date.
●
Maintenance
 Place a module removed from the unit on a conductive mat or conductive bag (used for a
backup board) on a grounded table.
Otherwise, parts may be damaged due to static electricity.
 Before touching the device or module, touch a grounded metal to discharge the static
electricity of your body. Otherwise, it may cause malfunction or failure due to static
electricity.
 Wipe off stain on the device or module with a soft cloth.
For severe stain, use a wet cloth wrung tightly.
Leaving them stained may cause wrong decision or malfunction.
 Do not use benzene or thinner to remove stain on device or module.
It may cause deformation or discoloration of the device panel or module.
 To keep the system normal and avoid unnecessary troubles, perform daily inspections,
regular inspections, and cleaning.
