The recorders of the EM-Card16 family are professional devices intended for making high quality record
of voice messages onto microSD memory card in wav format. The format is supported by all flash
players on the PC and any other playback devices.
2. Main Features
• long recording duration. Up to 1088 hours depending on the capacity of memory card in use
• the option to enable recording automatically according to sound activation.
• long recording duration in sound activation mode (up to 1 year)
• built-in clock and calendar, the option to enable recording at the preset time using timer.
• the Recorder is operational under wide temperature ranges under shaking or dustiness.
3. Overlook
The Recorder is designed for high-quality audio recording . The device is powered by a built-in
rechargeable battery, with microSD card as data carrier. During recording, the files are saved on the
microSD card in WAV format. The Recorder features built-in real-time clock and 4 timers to
automatically enable recording. It also has the option of recording according to voice activation and the
display of remaining battery charge level. Real-time clock automatically takes into account leap years
and various number of days within months. There is a configuration file on the memory card to
configure Recorder's functions. Its contents can be changed on the PC using any word processor.
LED indicator is used for indication, its color being green or red. The Recorder has a Switch, its position
being either ON or OFF. When the Switch is in OFF position, all the functions of the Recorder are off.
After the Switch has been shifted to OFF position, the Recorder may need some time (up to 30 sec) to
complete current functions and switch to the "off" state. Shutdown of the indicator states, the Recorder
has completed current functions and switched to OFF state.
