the built-in microphones using the built-in MICROPhONE SENSITIVITY SELECTOR (12). The high  
sensitivity level of the built-in microphone is -45dB (at 1Khz), while the low sensitivity level is  
-35dB (at 1KHz). You may also adjust the AUDIO IN VOLUME CONTROL (7 & 8) to make slight vol-  
ume adjustment.  
2. There are two Audio-in jacks for the Pocket Record a left and a right (9 & 10). They allow you to  
plug two extension microphones into the jacks for recording. If you use an extension microphone  
you must put the AUDIO IN SELECTOR switch (11) in the microphone “M” position. The two AU-  
DIO-In jACKS (9 & 10) both provide DC 1.5V power. You may use either the built in microphones or  
extension microphones as recording sources. When using extension microphones you may adjust  
the AUDIO IN VOLUME CONTROL knobs (7 & 8) for a proper recording sound level.  
3. The recording source of the built-in microphones and the extension microphones will be mixed  
into two separate tracks (Left and Right channels) with a balanced level.  
4. You can turn off the built-in microphones when recording using another source. Simply, switch the  
MICROPhONE SENSITIVITY SELECTOR (12) to the OFF positions.  
RECORD FROM ElECTRIC GUITaR OR lINE IN:  
1. The Pocket Record allows you to plug in an electric guitar as recording source. When using an  
electric guitar you must put the AUDIO IN SELECTOR switch (11) in the Guitar “G” position. When  
using an electric guitar you may adjust the AUDIO IN VOLUME CONTROL knobs (7 & 8) for a proper  
recording sound level.  
2. The Pocket Record allows you to plug in a line-in source such as a CD player, tape deck, radio,  
etc as a recording source. When using a line in source you must put the AUDIO IN SELECTOR  
switch (11) in the Line In “L” position. When using a line in source you may adjust the AUDIO IN  
VOLUME CONTROL knobs (7 & 8) for a proper recording sound level.

gram below shows the best sound recording area.

R
MDR-2  
2. To get the best recording result, we suggest that you put the Pocket Record at a distance of  
around 60cm from the sound source, at about table height.  
3. Adjust the input volume to a proper level. Do not set the volume to the highest level when record-  
ing, otherwise, the recording sound quality will be distorted.  
4. In situations where multiple instruments are played simultaneously, the Pocket Record should be  
positioned closest to instruments with lowest sound levels – or you can use extension microphones  
for the different instruments.  
5. If you want to record a speech (e.g. from a teacher) together with instruments playing, it is best,  
and we suggest the speaker uses the extensional lapel microphone to get the best results.  
6. For a better recording quality, the extensional lapel microphone could also be clipped to a score  
stand or on the body of the speaker, depending on the situation.

The device can be connected to computer, to copy and store your recorded files onto your computer  
(to backup your data), or download/transfer music from your computer to the Pocket Record.  
Connect one end of the USB cord to the port of the Pocket Record and the other end of cord to  
USB port on your computer.  
Once connected to your computer, the computer will detect the Pocket Record as two removable  
disks/hard drives (the first disk/hard drive represents the built-in flash memory; the second disk/hard  
drive represents the SD card memory). In each disk/hard drive you will find folders for Groups 1–9.  
The music you download from your computer to the Pocket Record will be stored in FOLDER 2, and  
the track number will depend on the sequence in which the files are transferred. This means that  
the track number in FOLDER 2 is not fixed and can be changed at any time if a track is deleted or  
added.  
If you want the files to have a fixed track number, you can store the music in FOLDER 1. To do this,  
you simply need to change the file names. Follow the instructions below to store files in FOLDER 1.  
a) If you want to download files to FOLDER 1, and store them in the built in flash memory, with a  
fixed track number, change the file name to M_InT_xx (xx is whatever track number you want it to  
be).  
b) If you want to download files to FOLDER 1, and store them to a SD memory card, with a fixed  
track number, change the file name to M_EXT_xx (xx is whatever track number you want it to be).  
The same way you connect to a wall outlet to power your Pocket Record you can power the Pocket  
Record off of a computer.  
Once you have connected to the computer, press the MODE/STOP button once, the Pocket Record  
will now enter the operating mode, and now you can operated the Pocke Record with the power of  
the computer.  
You can leave the operating mode by pressing the MODE/STOP button for 2 seconds.
