Uni-Directional Microphone minimizes recording of peripheral sounds and is ideal for recording speaker at lectures and presentations. 3 Mic Sensitivity Modes (Lecture/Normal/Dictation) lets you select best pickup sensitivity for recording a wide range of applications, from close-up personal dictation to large meetings. Desktop Mic Stand allows the recorder to be set down on table or desk for hands-free operation. Voice Operated Recording (VOR) automatically activates the recorder only when audible sound is present, conserving tape and eliminating lengthy noiseless passages on recordings. Clear Voice Sound System enhances voice quality during recording and playback for greater clarity. Cue Marker Indexing lets you place an electronic "mark" at specific tape segments, and provides rapid access during Cue and Review. Fast Playback plays tape 20% faster than normal speed and reduces the time needed to review recordings. Up To 19 Hours Battery Life using just two "AA" batteries for recording convenience. 3-Digit Tape Counter provides a digital display of tape elapsed for rapid access to a particular section of the tape during playback. 3 LED Indicator visibly indicates recording level and condition of battery power, in three segments. Playback Speaker is unobtrusive, and lets you and others hear playback without an earphone. Automatic Shut-Off helps reduce mechanical wear and conserves battery power. Pause Switch temporarily halts recording or playback without leaving that mode, and resumes at the flick of a button. 2-Speed Operation (1.2/2.4 cm/sec) gives you the option of recording on a standard microcassette for twice its normal time, for extended dictation or recording sessions. Cue/Review Function provides sound during fast Forward and Rewind modes to help find specific passages. Earphone Jack provides individual listening to playback for privacy.
