Overlook, Recorder's Appearance  

CARD24S (A101) Recorder is a professional device intended for sound recording in WAV format onto microSD memory 
card. The recordings can be played back using headphones connected to the Recorder with 2.5 mm mini-jack connector, 
or any device supporting operation with microSD memory cards and audio files in WAV format. The recording is made in 
stereo format, the signals of two tracks are formed by microphones located inside the Recorder's body according to the 
original scheme. This provides both stereo recording format and a uniform directional pattern. The files are recorded 
onto a microSD memory card installed into the Recorder, the built-in rechargeable battery providing high autonomy 
level. The Recorder has a timer recording function set for a specific date and time. The Recorder is controlled using two 
buttons REC and PLAY marked with symbols [R] and [P], respectively. 

LEDs are used to indicate the Recorder's battery charge level and free memory capacity. 

Setting the operating modes of the Recorder is carried out using a special configuration file previously recorded on the 
memory card. 
There is a configuration file on the memory card to set Recorder's operation modes.  This is a regular text file and can be 
edited with any text editor on the PC.
