OPERATING INSTRUCTIONS

SETUP

The headphones connect to the headphone output jack ( ). When using an Extra User Package (sold separately), connect the 3.5mm splitter cable to the Delight Plus and connect each set of headphones to the splitter cable. Please ensure that you have the side marked “L” on your left ear and the side marked “R” on your right ear. It is recommended that you disconnect the headphones from the unit before storing or travelling to prevent accidental damage to the jack.

The Tru-Vu Omniscreen, Tru-Vu Omniscreen Viewhole, or Tru-Vu Omniscreen Multi-Color Eyeset connect to the eyeset output jack ( ) with the included

2.5mm patch cord. Connect one end to the Delight Plus and the other to the jack located on the lower left of the glasses. When using an Extra User Package (sold separately), connect the 2.5mm splitter cable to the Delight Plus and connect each eyeset to the splitter cable. It is recommended that you disconnect the eyeset cable from the device and from the eyeset before storing or travelling to prevent accidental damage to the jacks.

An external audio source (such as an MP3 or CD player) can be connected to the Delight Plus so that music or other audio can be listened to while running a session. Plug the stereo patch cord into the headphone output of the audio device and the audio input jack ( ) of the Delight Plus.

Note: start the Delight Plus and select a session before playing audio unless you would like to run a Sound Sync Session (see page 6).

POWER

The Delight Plus can be powered with a 9-volt alkaline or rechargeable battery, or with the 9-volt adapter provided. To install the battery, slide the cover off of the battery compartment on the back of the unit. Insert a 9-volt battery as indicated on the diagram in the battery compartment. Slide the cover back into place. An alkaline 9-volt battery will provide approximately seven (7) hours of operation

To use the 9-volt adapter, connect the adapter to the 9-volt jack ( ) on the side of the unit. The 9-volt DC power adapter uses a 1.3mm center-positive plug. No battery power is used when plugged into an adapter.

[4]

The Delight Plus remembers which group was used last, and each group remembers which session was used last.

OPERATING INSTRUCTIONS

TURN ON/TURN OFF

Press and hold the power button ( ) until the power LED turns on. The graph (between the VOL and INT controls) will display the battery level when you first turn on the unit (see Battery Level). If no session is selected within two (2) minutes, the Delight Plus will turn off.

At the end of a session, the lights and sound will fade out (Soft Off™) and the Delight Plus will automatically turn off. To end a session early, press and release the power button ( ) to initiate a short Soft Off™ (30 seconds).

To turn off the Delight Plus at any time, press and hold the power button ( ) until the unit turns off. This may take up to three (3) seconds if a session is running.

BATTERY LEVEL

The battery level is displayed on the graph for a couple of seconds when the Delight Plus is first turned on. The battery level is also monitored and displayed periodically while the session is running.

When the battery level is getting low, the graph will display two (2) blinking bars. It is recommended that you replace the battery before running a session if this warning is displayed.

When the battery level is critically low, the graph will display a single (1) blinking bar. If this warning is displayed when you turn the unit on, replace the battery. If this warning occurs during a session, the session will end early and the battery indicator will continue to blink for a short period of time. The battery must be replaced before the unit can be used again.

SELECTING A SESSION

The Delight Plus has six (6) session groups ( , , , , , ). Each group offers five (5) sessions. The session number is indicated by the lit number between the volume and intensity controls. If no number is lit, then the group has no session programmed into it.

Press and release the power button ( ) to switch between groups. The lit group icon will change. Press the volume or intensity or to highlight a session number. If no sessions are available in a group, no numbers will be lit.

Press to start the selected session. The session will begin after a five (5) second delay.

[5]

Sound sync sessions use randomization. The left and right frequencies will vary slightly from the target rate to create a lucid mind-state.

SOUND SYNC SESSIONS

The Delight Plus has the ability to use sound to run a special session for relaxation and lucid dreaming effects. To start a sound sync session, connect

your audio device (eg CD or MP3 player) to the audio in jack ( ) with the 3.5mm stereo patch cord provided.

Turn on the Delight Plus, but do not select a session. Start the playback on the audio device. After a short period (about 10 seconds) the Delight Plus will detect the audio and enter sound sync mode. The graph will activate to indicate

there is audio present and the session group icons will flicker, with the selected icon lit solid.

Press and release the power button ( ) to cycle between group icons. Press the tone button ( ) to start the selected session.

A sound sync session will last for as long as audio is playing. Once the audio ends, the session will Soft Off™. If audio is detected again during the Soft Off™, the lights will fade back up and the session will continue.

USER DESIGNED SESSIONS

The User Designed session group ( ) has been left blank for storing additional, or user created sessions. This provides space for five (5) standard sessions and one (1) sound sync session. Sessions are created using the DAVID Session Editor (sold separately). Additionally, any session in the Delight Plus may be overwritten allowing the device to be customized with sessions to best suit your application.

Once the desired session(s) is created, it must be saved with the appropriate Session ID to be stored in the Delight Plus. The DAVID Session Editor v2.0 makes this easy. If you have an older version of the session editor, please contact Mind Alive Inc to get the latest version.

USER DESIGNED SOUND SYNC SESSIONS

Sound sync sessions have special design restrictions. When played, they have no specified length, and a single target frequency per visual field. To create a sound sync session in the DAVID Session Editor, start with a new session and select sound sync from the session type list. The Left and Right frequencies will be the target frequency around which the session will randomize.

Sound sync sessions may not be stored in a standard slot, nor may a standard session be stored in a sound sync slot. The Delight Plus will display an error if the session type downloaded is incorrect.

Please refer to the help files included in the tutorial on the DAVID Session Editor on creating sessions and instructions for downloading them into your Delight Plus.
