Getting Started

Step 1: Preparing a Power Source

Remove the film on the display window  before you use the IC recorder.

Inserting the batteries

3 Charge the batteries by connecting
the (USB) connector of the IC recorder to a computer that is currently turned on.
Computer
To USB port of your computer
Getting Started
1 Slide and lift the battery
compartment lid.
2 Insert two NH-AAA rechargeable
batteries with correct polarity, and close the lid.
To (USB)
connector
USB connecting cable
IC recorder
While the batteries are charging, “連接中”  and the battery indicator are displayed in  an animation.
When the battery indicator indicates “ charging is completed. (Charging time:  approx. 4 hours*)

When you use the IC recorder for the  first time, or after you have not used the  IC recorder for a certain period of time,  it is recommended that you charge  the batteries continuously until “
” is 
displayed.
If the battery indicator is not displayed,  charging has not been done properly.  Proceed from step 1 again. 
*  This is an approximation for the time it takes 
to charge from no remaining battery power  to full battery power at room temperature.  It varies depending on the remaining power  and the condition of the batteries. It also  takes more time if the temperature of the  batteries are low, or if the batteries are  charged while you are transferring data to  the IC recorder.

Disconnecting the IC recorder from your computer

Follow the procedures below; otherwise,  data may be damaged.
1 Make sure that the operation
indicator is not ashing.
2 Disconnect the USB connecting
cable connected to the IC recorder from the USB port of the computer.
On the Windows screen, left-click  “Safely Remove Hardware” on the  taskbar, and click “Safely remove USB  Mass Storage Device.” 
On the Macintosh screen, drag the “IC  RECORDER” on the desktop to “Trash”  and drop it there.
For details on disconnecting the  IC recorder, refer to the operating  instructions supplied with your  computer.
Tips
You can charge the rechargeable batteries 
by connecting the IC recorder to an AC  outlet using a USB AC adaptor (not supplied)  (page 121).
When replacing the batteries, messages 
recorded or alarm settings are not erased  even when you remove the batteries.
When replacing the batteries, the clock 
continues moving for a certain period of  time after you remove the batteries.
Notes
While “ ” or “ ” is flashing instead 
of the battery indicator, you cannot charge  the batteries. Charge the batteries in an  environment with a temperature of 5 °C 
- 35 °C. If “
USB充電” in the “細部選單” menu is set 
to “
”, you cannot charge the batteries 
using your computer. Set “
USB充電” to “” 
(page 88). During playback using the internal speaker, 
you cannot charge the batteries. When you use the IC recorder with 
rechargeable batteries, the battery indicator  may not light fully.
You cannot charge the batteries of your IC 
recorder while your computer is in the sleep  mode, even if the computer is turned on.
Clock setting display appears and the  year section flashes when you insert  batteries for the first time, or when you  insert batteries after the IC recorder  has been without batteries for a certain  period of time. Please refer to “Setting  the clock after recharging batteries” on  page 18 to set the date and time.

When charging/replacing the batteries

The battery indicator on the display  shows the battery condition.

Recording at a meeting
Set “錄音等級” to “  ” or “較高  ” in 
the menu (page 30). Slide the DIRECTNL switch to “ON” to 
record a voice coming from a specific  direction (page 26).
Set “LCF (LOW CUT)” to “ to prevent noise caused by a projector,  etc. (page 37).
By placing the IC recorder on the stand,  you can record with clear and low­noise sound, without vibration noise  from the desk.

Recording a musical performance
Set “錄音等級” to “音樂  ” (page 30) 
in the menu to record more natural  acoustic sound, with preventing  sound  distortion. For more realistic sound  recording, you can adjust the recording  level manually by setting “ “手動” (page 31).
Set “LIMITER” to “

Recording dictation (using the voice recognition software)
Set “錄音等級” to “  ” in the menu

record a voice coming from a specific  direction (page 26).
To transcribe a message recorded on 
the IC recorder using voice recognition  software (not supplied), set “ to the LPCM, MP3 or LPEC (except LP)  mode (page 27).
Microphone
Before you can transcribe recorded 
messages, you have to create a user file  specifically adapted to the sound of your  recorded speech. This procedure is called  “training.” For details on “training,” refer to the  help files supplied with the voice recognition  software you are using.

To obtain maximum recognition accuracy, 
hold the IC recorder so that the microphone  is about 2 - 3cm from the corner of your  mouth.
To minimize the sound of your breath in the 
recordings, do not hold the microphone  directly in front of your mouth.
To obtain maximum recognition accuracy, 
avoid recording in a noisy place. You cannot transcribe a message recording 
the voices of more than one person.
Turning the IC Recorder On or Off
When you are not using the IC recorder,  you can prevent the batteries from  getting weak quickly by turning the  power off.
Turning the power o
Slide the HOLD switch in the direction  of the arrow in the stop mode. “HOLD”  with the key mark and the current time is  displayed, then “

Turning the power on

Slide the HOLD switch in the opposite  direction from that of the arrow. The IC  recorder turnes on, and an accessing  animation is displayed.
Tips
When you are not going to use the IC 
recorder for a long time, we recommend to  turn off the IC recorder.
About 10 minutes after you have turned 
on the IC recorder and left it without doing  anything, the display goes off automatically  and the IC recorder turns off. (Press any  button to show the display.)
