Example : DSP 02.06 MPU B00043) Turn off power to quit Service mode.2. CompactFlash read/write speed check
18、1) Insert the CompactFlash, While pressing A-B REPEAT and EDIT buttons, Slide POWER switch to turn on the unit.2) VIRSION name is displayed on LCD with blink, then press -/F.REV or F.FWD/+ button.3) CARD CHECK name is displayed on LCD with blink, then press PLAY/PAUSE button. The check of Read/write
19、 speed is started. After the check fi nishes, the number of data transfer rate (kbps) is displayed. Start (progress) End Example : XXX% Read:3606 EXECUTING Write:3606 If about 3000 or less number is displayed, the CompactFlash is not correct (Because read/write speed is slow, the unit has the possib
20、ility that sound is interrupted and stop during recording). Insert the correct CompactFlash.4) Turn off power to quit Service mode.2. FACTORY/SERVICE?A.
