31、escorresponding to the pressed number are displayed. (Thedisplayed values are those in the RAM.)5: Vary each setting value using 4 or 6: Store the values in the corresponding preset number.7: The settings can be performed individually for each item. (Itis not required to store all the values togethe

32、r.)8: After storing the values, reset the unit to exit from theadjustment mode. The values set in the EEPROM will beread during the resetting.9: When the band is switched, there may be cases in whichthe preset number being displayed does not coincide withthe stored setting value. To check this , be

33、sure to recall thepreset number after you switch the band.Notes1: The items which are not stored will be set to the defaultvalues.2: Once a value is stored in memory, the value will always beused later.(It is not allowed to modify the setting values by switchingthe destination type.)A B C D E F G IH
