DragonEEG

PURPOSE OF THE DRAGONEEG

The DragonEEG system is designed for recording brain biopotentials, with the capability of simultaneously recording signals from polygraphic channels. The system records electroencephalograms (EEG) with up to 21 channels, according to the generally accepted "10-20%" or "10-10%" EEG electrode placement schemes.

However, it does not provide report generation for diagnostic purposes. The system is not intended for clinical research.

The DragonEEG system is intended for use in:

Psychologists' offices
Research laboratories
Universities
Rehabilitation centers
Other organizations involved in brain research and neurotechnology development

The DragonEEG Wireless Brain Biopotential Monitoring System is safe and reliable. It complies with international and national standards and meets the requirements necessary for its intended use as defined by the manufacturer.

DragonEEG Operating Modes and LED Indicator

The DragonEEG device operates in three distinct modes: Turned off, Turned on, and Pairing mode.

1. Turned off: The device is completely powered down, and no LED indicators are active.
2. Turned on: To turn on the DragonEEG, simply click the power button. Once activated, the power button should be immediately surrounded by a solid red light. In this mode, the device is operational but not actively seeking a new Bluetooth connection.
3. Pairing mode: To put your DragonEEG into pairing mode, first ensure the device is turned on. Then, hold down the power button for approximately 5 seconds. When the device successfully enters this mode, the LED indicator on the DragonEEG should begin to flash quickly. This rapid flashing is the visual confirmation that the device is ready for a connection attempt.

To turn off the DragonEEG device, simply click the power button while it is in either the Turned on or Pairing mode.

Device indication and operating modes:

LED off: The recording module is off.
LED flashes 3 times: The recording module is powering on.
LED is on: The recording module is on and in standby mode.
LED flashes continuously (0.1s on, 0.7s off): Signal recording is in progress.
LED flashes quickly: Device is in pairing mode and ready for a connection attempt
LED flashes (0.25s on, 0.25s off): The recording module is charging.
LED is on (when the power supply is connected): The recording module is fully charged.

To turn the recording module on/off, press and hold the button for 2 seconds.
