Entering Service mode: Do be careful! It's pretty similar to most of the other Sharp portables but the battery compartment must be OPEN - i.e. the unit must have NO POWER. 1) Press and hold PLAY, SYNC[Enter] and DISP buttons. 2) THEN drop in the battery and close the compartment (or apply external power - eg turn on the DC power source). Display shows the EEPROM version code, followed by all symbols lighting up, followed by the standard Sharp test menu. My EEPROM version code is 921AcX. -Dave Hooper Gadget Squad reviews the Sharp MD-MT831, with favorable findings.

Specs: Motor speed: 400-1350 rpm, headphone amp: 10mW + 10mW * Headphone volume at 0 during recording and 15 during playback.
