TROUBLESHOOTING Trouble1 : Power turns off while in operation. cause1 To prevent CF data error, the unit will automatically turn off when CF cover opens. For product serial number 1022100 (program version 98082901) a shock to the camera (i.e. key operation, lens rotation, etc.) may produce chattering to CF switch which may erroneously detect that CF cover is open. To prevent this change the software. Program to use (CF card × 1) KX-778PROGRAM Ver.
(4) Check program Ver. Insert CF card that comes with the unit. Then turn power on pressing DISP button and MENU button at the same time. Make sure program version is 98100102. Turn power off then on again and make sure recording and playing functions alright. LCD display TEST MODE NOISE DATA YES LOADER 2 ADJ. 98000829 VER. 98082901 ➝ WHITE Program version (5) Erroneous correction check Insert the CF card that comes with the unit. Turn power on, then tap the right side of the unit with a finger.
Trouble5 : Display shows; CF CF ERROR FORMAT MENU cause1. Error in CF data. action1. Refer to the owner’s manual. CF can be handled the same way as hard drive. The actions noted below can be taken. No guarantee about the display. (1) Set CF card to a PC using PC card adapter. (2) Save files in the memory card. (3) Execute scan disk program for CF card and recover the data error or format the disk. (4) Copy the correct file in memory card. cause2. CF card hard error. (Unable to format or scan disk) action2.
Trouble9 : Display failure when flash is used. cause1. Noise when flash is in operation. action1. Refer to “Strobe operation check on page 8”. Trouble10 : Unable to switch between REC and PLAY. cause1. Switch unit broken or bad installation. action1. Replace or reinstall switch unit. Trouble11 : Wrong time cause1. Time data error. action1. Reset time. cause2. Lithium battery is dead. action2. Replace lithium battery. cause3. Bad DA PCB ass’y. action3. Refer to ”Clock oscillation check” on page 13.
