GETTING STARTED
Your new LectroFan EVO came with this guide, an AC power adapter, and a
USB cable. You can power it by using the USB cable with the AC adapter, or
by connecting it to a PC or any powered USB hub.
Tip: Your LectroFan EVO needs to be connected to a power source to operate.
The USB cable provides power. It does not support USB audio. By default, the
LectroFan EVO turns on automatically when it’s plugged in, but you can change
this. See Disabling Automatic Power-On later in this guide.
SELECTING SOUNDS
Press the noise and fan buttons to select from the sounds oered by each. You’ll hear
a short tone when you’ve reached the last sound and your LectroFan EVO is back to
the first sound.
The LectroFan EVO will automatically remember the last noise and fan setting when
you switch between modes and saves the most recently used noise and fan setting
when you turn it o.
Tip: To save your last setting be sure to use the “power o” button. The last setting
will not save if you unplug the unit or turn it o using a power strip.
Tip: If you’d like to step through the sounds in reverse order, press and hold the noise
or fan button for three seconds.

USING THE TIMER
LectroFan EVO plays continuously, but you can use the optional timer to gently
turn it o automatically. Tap the timer button to begin. You’ll hear a short rising
tone, indicating that the timer has been set for one hour. Each time you tap it,
another hour will be added. When you hear a short falling tone, the maximum
of eight hours has been reached.
To cancel the timer, turn the EVO o, and then on again.
DISABLING AUTOMATIC POWER-ON
If you prefer that the LectroFan EVO not turn on immediately, you can disable
this feature:
1. Turn o the LectroFan EVO with the power button.
2. Press and hold the volume down button.
3. While you’re still pressing the volume down button, press and release
the power button.
RESTORING FACTORY SETTINGS
Restoring factory settings will set the LectroFan EVO to turn on automatically, and
reset the default sounds and volume level. To restore the factory settings, turn o
the LectroFan EVO then press and hold the power button until you hear a tone.
USING THE AUDIO OUTPUT CONNECTOR
Your LectroFan EVO has a 3.5mm analog audio jack which you can use to send
sound to a pillow speaker, portable speaker, headphones, or any audio device
which uses a 3.5mm plug. When you connect an external speaker, the built-in
speaker is turned o.
As with any audio source, be sure to keep the volume at a comfortable level
when using headphones or ear buds.
