AVE OPERATING INSTRUCTIONS
SETUP
The headphones connect to the headphone output jack ( ). When using an Extra
User Package (sold separately), connect the 3.5 mm splitter cord to the Delight Pro
and connect each set of headphones to the splitter cord. 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 2.5 mm
eyeset cord. Connect one end to the Delight Pro and the other to the jack located on
the lower left of the glasses. When using an Extra User Package (sold separately),
connect the 2.5 mm splitter cord to the Delight Pro and connect each eyeset to the
splitter cord. It is recommended that you disconnect the eyeset cord from the unit
and from the eyeset before storing or travelling to prevent accidental damage to the
jacks.
An external audio source can be connected to the Delight Pro so that music or other
audio can be listened to while running a session. Plug a 3.5 mm stereo patch cord
(sold separately) into the headphone output of the audio device and the audio input
jack ( ) of the Delight Pro.
Note: start the Delight Pro and select a session before playing audio unless you
would like to run a Sound Sync Session (see page 7).
POWER
The Delight Pro can be powered with a 9-Volt alkaline or rechargeable battery, or
with the 9-Volt power adapter provided. To install the battery, slide the cover off 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 power adapter, connect the adapter to the 9-Volt jack ( ) on the
side of the unit. The 9-Volt power adapter uses a 1.3 mm center-positive plug. No
battery power is used when plugged into an adapter.
Note: to prevent accidental shock the CES capabilities will be disabled when a power
adapter is connected. To use the CES functions disconnect the adapter and run from
battery power only.

[4]
The Delight Pro
remembers which group
was used last, and each
group remembers which
session was used last.
AVE 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 Pro will turn off.
At the end of a session, the lights and sound will fade out (Soft Off™) and the Delight
Pro 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 Pro 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
Pro 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 Pro has six (6) session groups ( , , , , , ). Each group offers five
(5) sessions, except . 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]
100 Hz CES
produces more
serotonin than other
frequencies,
boosting relaxation
and helping to
improve sleep.
CES OPERATING INSTRUCTIONS
SETUP
To use the CES feature of the Delight Pro, the unit must be powered from a 9-Volt
battery. If a 9-Volt power adapter is plugged in, the CES will be disabled as a safety
precaution against electrical shock. Make sure to disconnect any adapter before
using CES.
The CES stimulus cable connects to the CES output jack ( ). Attach the black clip to
the left earlobe and the red clip to the right earlobe. For better conductance, it is
recommended that you dampen the earlobe with a small amount of water, saliva,
saline solution, or hair/electrode gel.
RUNNING CES
CES will only operate while an AVE session is running. The rate of stimulus can
either be synchronized with the AVE (default) or run at 100 Hz. When using CES by
itself, you can operate it while lying down or engaged in a simple, non-hazardous
activity such as walking, reading, or office work.
Follow the instructions for selecting a session (page 4). Once the session has started,
press the CES button to start the CES pulses. The CES system normally remains
off and must be manually engaged every time you want to use it. Turning down the
stimulus level all the way will turn off the CES system. The CES system can be turned
on or off at any point during the session.
The “L” and “R” LEDs (along the top edge of the panel) blink to indicate that CES
pulses are active. These LEDs blink at the CES stimulus rate. The “100 Hz” LED light
indicates that the CES is operating at 100 Hz.
100 HZ FREQUENCY
By default, the CES stimulation is synchronized with the AVE stimulation in the
running session. When you first turn on CES, the rate of pulses will be the same as
the AVE frequency. To engage 100 Hz at any time,
press both the CES and buttons together.
Press them again to return to AVE frequencies.
It is recommended that you engage 100 Hz
frequency when the CES intensity is set low, as the
sensation from 100 Hz stimulus is often much
stronger than in AVE Sync mode.

[6]
Please refer to
page 19 for CES
Troubleshooting.
CES OPERATING INSTRUCTIONS
CES INTENSITY
The CES stimulus level can be adjusted at any time using the CES or buttons.
The graph displays the current CES stimulus level as you are adjusting it. The top-
most lit LED will blink to indicate the level is being adjusted.
The intensity of the CES stimulus should be adjusted to a level so that the stimulus is
only mildly noticeable. Over forty double-blind studies have shown that CES works
at a sub-threshold level (below the level of feeling). Setting the intensity too high
may result in a mild irritation or blistering of the skin.
After a few minutes, you may notice that the intensity of the stimulation is stronger.
This is due to a normal “sweating in” to the ear clips that results in a better electrical
connection. Re-adjust the intensity to a comfortable level.

[7]
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
Each category includes a sound sync session which is great for relaxation and lucid
dreaming effects. To start a sound sync session, connect your audio device to the
audio in jack ( ) with a 3.5 mm stereo patch cord (sold separately).
Turn on the Delight Pro, but do not select a session. Start the playback on the audio
device. After a short period (about 10 seconds) the Delight Pro 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.

tones, press and release the tone button ( ). The tones will cycle through the
available tone options (see page 2). To turn on the heartbeat, press and hold the tone
button ( ). Press and hold the Tone button ( ) again to turn the heartbeat off.

[8]
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 Pro.
USER DESIGNED SESSIONS
The User Designed session group ( ) has three (3) gamma (40 Hz) sessions and
two (2) blank spaces for storing additional, or user-created sessions. Sessions are
created using the DAVID Session Editor (sold separately). Additionally, any session in
the Delight Pro may be overwritten with the Session Editor to customize the
sessions to best suit your application.

[9]
Add CES to any session. CES can follow
along with the AVE stimulus or run at
100 Hz for relaxation. See page 5 for
instructions on setting up CES.
We recommend running sessions with
eyes closed for best results. Viewhole
eyesets are available for an
additional cost.

WARNINGS
CRANIO-ELECTRO STIMULATION (CES)
•Do not use if you have a heart pacer. The electrical signals may cause the
pacer to malfunction, leading to serious injury or death.
•Do not use on anyone with epilepsy, brain tumor, or who has had a recent
stroke.
•Do not use while driving or operating hazardous machinery.
•Do not place electrodes over skin lesions, new scars, cuts, eruptions, or
sunburn.
Setting the intensity too high may result in a mild irritation or blistering of the
skin. Set the intensity to a lower level so that the stimulus is only mildly
noticeable. Double-blind studies show that CES works at sub-threshold (below
feeling) level.
PRECAUTIONS
Traumatic Childhood Experiences - The DAVID Delight Pro can cause the
release of suppressed memories. If traumatic memories surface during or after a
session, be certain to seek appropriate support.
Startle Response - If abruptly returning to a normal conscious state, the user may
feel disoriented, nauseous, or experience a headache. All preset sessions in the
DAVID Delight Pro are programmed to end with the lights and sounds gradually
fading out (Soft Off™) to avoid a startle response.
Orthostatic Hypotension - Occasionally when a person becomes very relaxed
during a session, their blood pressure may fall significantly. We advise rising slowly
after a session.
