Installation Instructions
To avoid false triggers, do not install in areas that have direct sunlight, areas with large
temperature variation, or near air conditioners and heaters.
This unit is designed for indoor use only. External use will result in moisture damaging internals
of the device and void the warranty. The induction window (area where motion can be
detected) is as illustrated below:
1. Attach to wall:
 Attach to wall directly or through included ball mount, either method can be used
 Using ball mount method allows you to adjust detection area while unit is in place
 Back of unit has 4 screw holes. Regardless of installation method chosen, only bottom 2
holes are used, upper ones are left unused
Directly to wall:
 Screw 2 screws provided into wall and attach unit by the bottom 2 screw holes
OR
Using ball mount:
 Screw part #5A into wall using 2 screws provided
 Insert part #5B into bottom 2 screw holes at back of unit
o Pongs should be pointing up when inserted and pushed up firmly into place
 Firmly push unit into part #5A attached to wall until the ball snaps into socket
 To detach from wall, pull unit firmly to detach part #5A from part #5B
2. Adjust Sensor Angle and/or Unit (if desired, applicable only to Ball Mount Installation

Charging
 Use the provided micro-USB adapter to recharge or keep plugged-in to use directly from outlet.
Recharge from empty will take up to 4 hours.
 Green LED will come on and stay on when fully charged
Adding Audio
1. Use a PC/notebook that has a USB slot and connect it to the device
2. Ensure the USB cable is a data USB cable. The provided cable is a data USB cable. Not all
cables are for data transfer, some are only for charging. If using your own USB cable, ensure
it is a data cable or your PC will not recognize the device
3. A new drive will show up on your PC. Write MP3 audio to the device. Ensure you only write
MP3 files to the device and no other types of files. All files must be placed in the root
directory, there should not be any sub-directories/folders.
IMPORTANT:
 Total size of audio file(s) must be less than 4MB to fit onto the device. If total size of
audio files you are trying to transfer is over 4MB, audio will not be transferred.
 To record your own voice/personalized messages, there are many free applications that
let you record MP3 audio
 An iOS/MAC device should not be used to write audio to the device as they leave hidden
non-MP3 files that will cause the device to not function properly

Mode Selection
MODE 1. Play a single file every time
 With device on, short press button “A” to go to the file you want to play and stop there.
 Now while the file is playing, hold button “A” for 3 seconds and release when the indictor light starts
flashing
 If after selecting a file, you later press A, the selection will reset and select this new file for playback,
even without pressing A again for 3 seconds
MODE 2. Play multiple files in sequence
 With device on, press button “B” and hold until indictor starts flashing.
 Playback will now be in the same sequence as written to the device. See below for important
details
TIP for Mode 2:
 Sequence of audio played follows the same sequence you used to transfer files to device’s
memory
 Copy files from your PC one by one to the device. Playback sequence will follow the copy
sequence
For example, if you have files called 001.mp3, 002.mp3, and 003.mp3 and you copy
those files to the device in this sequence:
002.mp3
then 003.mp3
then 001.mp3
then playback under mode 2 will be in that same sequence:
002.mp3
then 003.mp3
then 001.mp3
Once motion is detected and audio is being played, the unit will not interrupt audio playback. It
will keep playing the current file until completion, after which it will wait approximately 1
seconds and start detecting new motion again.

Powering the Unit
The unit can be powered directly from an AC outlet using the supplied USB power adapter, or it
can be powered using the internal rechargeable battery. To recharge battery, simply connect
the USB power supply to the unit. Once fully charged, the built-in protection circuit will
automatically disconnect charging. When the unit is turned on, it goes through an initialization
process where it may take 10-30 seconds after power up for it to start detecting motion. During
this time, the green and red indictors will be flashing.
If you notice the performance of the unit degrading, such as lower sound volume or it is not
detecting motion, this indicates the battery is low and needs recharging. The factors dictating
how long the unit lasts on a single charge are:
o Activity in the room (how often unit triggers)
o Duration of audio files
o Volume setting selected
When using battery power, the unit will go into low power mode when no motion is detected
to save power. It will automatically wake up when motion is detected.
Example Applications
 Promotes Independent Living:
o “Check that you have your keys, wallet, and cell phone before leaving”
o “Turn off oven before leaving”
 Door Greeter/Notifier for entrances and storefronts
o Senses people coming in and plays greeting, uses at shops, events, parties
 Point of Sale Advertising:
o Place near products, automatically plays advertising material when customers
pass by
 Safety Reminder
o Plays a reminder as soon as personnel enter a restricted area
o Use to instruct pets to avoid certain areas when you are away
 Exhibits /Trade Shows
o Pre-record material and have it played automatically to visitors at your booth

Frequently Asked Questions
Q: I wrote files to the device but the device is not playing back audio.
Ensure your device only has MP3 files on it and no other files. Any file other than MP3 must be
deleted. Ensure that the total size of all files is less than 4 MB.
Q: When I write to the device using a non-Microsoft Windows operating system (such as
MAC), the unit is not playing back audio or not all features work as described.
Some systems write hidden files to the device. MACs/iOS devices will very often leave such files
and cause the device to not function properly. Using a Windows PC is the safest and guaranteed
method.
Q: Can this product play WAV audio? If not, what is the solution?
This product only supports MP3 audio but there are plenty of free WAV to MP3 converts
available online
Q: During use, playback gets interrupted then continues to play and this repeats
This is caused by an unstable voltage and indicates that the battery is low. Recharge the battery
Q: After the unit is powered on, there is a period of time where there is no response or
delayed response.
After power on, there will be 10-20 seconds of power initialization time. During this period, it is
normal to have no or slow response. After this time, the unit will work normally
Q: I want files to be played in a specific sequence. Can you suggest an easy way to do this?
Files are played back in the order written to device memory. You can copy files manually one by
one in the sequence desired.
Q: What if I want to play audio say 2 minutes after detecting motion and not right away?
Create an audio file where the first 2 minutes are silent and followed by your non-silent part.

A Note about MP3
MP3 is a popular format for sound files and supports different bitrates. As with all MP3 files and
devices, the playback time is dictated by the bitrate of your audio files. Recording programs
often give you the option of selecting which bit rate to use. A recording with a higher bit rate
provides better sound quality but also larger files.
