This document describes how to set the time and date on a recorder.
This guide explains how to install batteries, set the time and date, and use the recorder’s four folders (A, B, C, and S) to organize up to 300 recordings. It also describes the three recording modes—HQ, SP, and LP—and how to adjust microphone sensitivity and the Variable Control Voice Actuator (VCVA) for efficient memory use.
Detailed instructions cover playback functions, fast‑forward/rewind, ear‑phone use, alarm scheduling, moving files between folders, and erasing recordings either singly or in bulk. Safety notices, FCC/CE compliance information, and troubleshooting tips are included throughout.
