5. The initial screen appears displaying name of the selected transducer along with its
version. Double check the transducer name from this screen.
(3) Precaution on the piezoelectric transducer selection
1. A combination among those transducers other than 3kw will be indicated with the
corresponding code. Normally, you should not select such combination. For
detail of the combinations, see Table 4.5.
(4) Description on the backup
1. The JFV-130HP employs EEPROM for the backup. Unlike current models, it
does not require a lithium battery replacement. However, since it is an electronic
component, damages can occur if your turn power off while the master reset is
taking place. If EEPROM fails to provide backup function at all, you should sus-
pect an error on it.
