WARNING
• The use of headphones at high volumes may cause ear and hearing problems as well as increased fatigue. Always listen at
moderately low volumes.
• If you feel the fatigue or discomfort, immediately stop listening.
• The headphone sound output level varies according to the headphones to be used, regardless of the preset volume level. If
you replace the headphones, adjust the volume again afterwards.

Setting filter conditions
Set the filter conditions of the CF-0473 amplitude modulation component extraction function, while listening the
correlation with the sensitive evaluation through the headphones, in the BPF & Monitor Setting dialog box that appears
after touching soft keys Home, Input, and BPF & Monitor in this order.
For details of the BPF & Monitor Setting dialog box, refer to the Reference Guide (PDF Help) stored on the CD-ROM that
comes with the CF-4700 FFT comparator.

CAUTION
• For details of the measurement methods and procedures of the CF-0473 amplitude modulation component extraction function,
refer to the Reference Guide (PDF Help) stored on the CD-ROM that comes with the CF-4700 FFT comparator.
5.2 CF-0478 Power Source Backup Function
The CF-0478 power source backup function is to automatically start or shut down the CF-4700 comparator without
operating the POWER switch by turning on/off the power to the AC adapter connected to CF-4700 FFT comparator. This
function is useful such as when using the CF-4700 FFT comparator incorporated into the equipment.
The CF-0478 power source backup function becomes available when the supplied battery pack is attached to the CF-
4700 FFT comparator.
• For this function, always use the specified battery pack for the CF-0478 power source backup function. When replacing the
pack due to the end of service life or purchasing another pack, be sure to purchase the battery pack specified by Ono Sokki.
Using a battery pack other than specified could cause a smoke, fire, electric shock or explosion in addition to failures and
malfunctions.
• Do not heat or disassemble the battery pack, short circuit it or throw it into fire. It could cause explosion or ignition.
• If the CF-4700 FFT comparator is expected not to be used for a long period, keep the battery pack removed from the
comparator. Keeping the battery pack installed for a long period could cause over-discharge, which could shorten the service
life.
• When carrying or storing the battery pack, wrap it in plastic bags so the electrodes will not touch metal, and carry or store it in
as cool an environment as possible. When transporting the battery pack independently, follow the transportation rules.
• When disposing of the battery pack, attach insulation tape to the electrodes for short circuit prevention and follow the local
ordinances and regulations. Otherwise, it could cause an explosion, fire, or environment destruction. Illegal disposal could also
be subject to punishment.

Checking items for CF-0478 power source backup function
• To use the CF-0478 power source backup function, the specified battery pack must be installed.
• The battery pack can be charged only while the CF-4700 FFT comparator is running.
The battery is not charged when the CF-4700FFT comapator is not started even if the AD adapter is connected to
the power source.
• The battery pack power alone is not sufficient for the POWER switch to start the CF-4700 FFT comparator.
• The device cannot be shut down normally while the battery level indicator on the upper right of the main screen
shows “charging”. Connect the AC adapter to which power is supplied and confirm that the battery level indicator
shows “fully charged”, then use the CF-0478 power source backup function.
• Even if the power to the AC adapter is interrupted and the power is supplied again to the AC adapter during the
shutdown process, the shutdown process is continued normally.
