Error Code :
There are three types of the error
1 : Normal Log Error, 8 : Physical Error, C : Logical Error

Purpose: To make the error log file in order to become more efficient the error analysis.
Procedures:

1. Enter the Test Mode, check all segments of LCD light up.
2. Set the Recording position switch to “WIDE”.
3. Press and hold the [VOL+] for 10 seconds and the unit will enter into the make error log file mode.

Any keys are no efficient while in this mode.

4. “ErrorLog.dat” is made in the root folder of the unit.
5. Remove the batteries to end this mode.

• Updating the firmware

1. Insert battery with sufficient battery charge.
2. Connect IC-recorder to PC using USB cable.
3. Copy "XXXXXXXX.ebn" file to IC-recorder root folder.
4. Terminate PC to IC-recorder connection safely 

(refer to icon at bottom right side of the monitor – "Unplug, Eject or Safely Remove Hardware"). 

5. Let IC-recorder perform system update, "UP" and "[F] ACCESS" will display on LCD.
6. Upon completing update, perform "FORMAT" function to erase all files in the IC-recorder.

– Press ERASE key
– Select the display which [FORMAT] is flashing in file erasing mode
– Select [YES] in the [YES   no] display

– Press [

]

• Checking Firmware Version

1. Press and hold [STOP] key for 10 seconds, LCD will display the firmware number.
