The Black Vox Calculator is a Professional Covert Audio recording device
designed for deployment anywhere a calculator would be. Built specifically
for long term deployments, the device has a recording capacity up to 288 hours and a standby time of over 75 days. Its highly sensitive microphone
allows for it to be easily hidden in plain sight and capture all important
conversations. The calculator is a fully functional calculator.
Accessing the Charger and Data Port
The charging and data port are located inside the calculator. To charge the
unit and to listen to recordings from the unit, you must remove the back
cover using a small phillips head screwdriver.
Charging the Unit
Make sure the unit is turned off before charging
You can charge the unit by plugging the 2.5mm cable (provided) into the
port inside the unit and the other end can be plugged into a PC, Laptop,
or a USB wall charger. While charging, a solid red light should be visible on
the circuit board. A full charge should take around 6 hours. Once complete,
the red light will start to flash.
To turn the recorder on and off, insert the thumb tack into the small hole on
the side of the calculator and press the on/off switch. This can be done with
the cover on or off. The recorder is on when the switch is in the down or inward
position. The recorder is off when the switch is in the up or outward position.
Plug the 2.5mm jack
into the Black Vox first
and then to the power
source. This prevents
shorting the unit out.

Pro Tip: If the light blinks
instead of turning solid
after you turn the unit on,
the battery is not fully
charged.
Once the device is fully charged, it is ready for deployment. To prepare the device for
deployment, use the push pin or a paper clip to press the power switch to the on
position. While in recording mode, the device will only record when it detects sound
and will stop recording when no sound can be detected. Each new recording will be
stored as a separate file.
The device has a sensitive microphone which allows for it to be placed in numerous
places. The device was specifically built for deployment in plain sight and the calculator can be used without affecting the operation of the voice recorder. Black Vox
Calculator can be placed within 33 feet (10 meters) of its target. It will record sounds
with crystal clear clarity when sound is detected.
Reviewing the Audio
Once you have finished recording the desired audio, you will want to play back the files.
To do this, turn off the Black Vox and connect it to a computer using the included USB
cable (if the device is left on, it will not show up on your computer). At this point, a new
drive should open up on your computer. Open the VOICE folder which contains all of
your recorded files taken during the deployment of the device. As with any normal file,
you can choose to move it, copy it or delete it in the normal fashion. Please note that
Mac users must empty the Trash while the unit is plugged in to actually delete the files
from the device. It is advised that you wipe the unit’s memory as often as possible.
This is due to the fact that the device records high quality footage that can quickly
fill up the unit’s memory causing the device to stop recording.

Setting the Time Stamp
The Black Vox Calculator allows you to change the time stamp on the
recordings. This allows the user to know when each recording took place
by looking at the Date Modified on each MP3 file created.
To set the time on your Black Vox to the same time as your Windows
computer, plug the Black Vox into a USB port. This should open a window.
Open the Time Setup.exe file by double-clicking it. This will open the
program shown below. Click the “Start” button and close the program.
Your Black Vox time stamp will now match your computer time.
Please Note: The Date modified is the time the recording stopped. To determine when it started,
you can subtract the length of the recording from the Date modified.
Mode (Record Quality)
XHQ = Super High Quality
HQ = High Quality
Note - XHQ requires more storage
space per hour of recording so your
total recording time stored will be
reduced.
SVOS Level
+2 = Most Sensitive
+1 = More Sensitive
0 = Default Sensitivity
-1 = Less Sensitive
-2 = Least Sensitive
More sensitive requires quieter sound
to activate and less sensitive requires
louder sound to activate.
Please Note: If the Black Vox battery is totally drained, you will need to reset the time stamp.
