Table of Contents Section 1: About Vault
Vault is the first-of-its-kind integrated, two-in-one
portable Faraday enclosure and audio masking
chamber for smartphones. Vault eliminates smartphone
signals more eectively than fabric-based Faraday
products, delivering a minimum of 100 dB of radio
frequency (RF) attenuation/10 billion times signal
reduction. When placed in the Vault case, a smartphone
can no longer be reached via cellular, WiFi, Bluetooth,
near-field communication (NFC) or radio-frequency
identification (RFID). User-controlled audio masking
prevents extraction of intelligible speech up to voice
levels of 90 dBA through independent noise signals.
The associated smartphone’s cameras are also unusable
when sealed in the enclosure to prevent spying.

VAULT COMPONENTS
At a basic level, Vault includes a lid, a base and a latch that joins the two together to create a radio frequency
(RF) seal. Vault also ships with a three-foot, USB-A to USB-C charging cable.
The components of Vault (and their main functions) are displayed in Figure 1.

Insert your smartphone into Vault using the following steps:
1. Open the lid (Figure 4). It may help to place the
base on a flat surface.
Before using Vault for the first time, it’s important to complete the following steps:
POWERING ON VAULT
Vault is in shipping mode when it arrives. To power it
on for the first time, connect Vault to a power source
(charge-capable USB port or wall charger) using the
charging cable provided. The USB-C side connects
to Vault and the USB-A side connects to the power
source (Figure 2). Once powered on, the battery
status LED will illuminate.
REMOVING SMARTPHONE ACCESSORIES
Before inserting your smartphone into Vault, remove
any protective cases and any other accessories from
your smartphone (Figure 3). Protective cases may
prevent your smartphone from fitting into the device
and may disrupt both RF shielding and audio masking.

2. Place your smartphone in the center of the interior
(Figure 5). Your smartphone should rest evenly on
the four pads.
With your smartphone in place, you can now turn on
audio masking (see: Managing audio masking).
3. Close the lid (Figure 6).
4. Lift from the bottom of the latch and place the
top of the latch onto the latch rail (Figure 7).
5. Firmly push the bottom of the latch inward to snap
into place (Figure 8).
With Vault securely latched, a tight seal is created
around the device to shield out any RF signals.
OPENING VAULT
When you would like to remove your smartphone from
Vault, adjust audio masking or charge the device, you
will first need to open Vault.
Open Vault using the following steps:
1. Pull the bottom of the latch outward (Figure 9).
2. Move the top of the latch o the latch rail
(Figure 10).

Vault provides two levels of audio masking – Maximum (for high noise levels) and Standard (for low-to-moderate
noise levels) – as well a Standby setting for when masking is not required (Figure 11).
To change the audio masking setting, with the lid open toggle the audio masking switch to the desired setting
(Figure 12). The audio masking LED reflects the current masking setting.

LED behavior Notes
Maximum masking For use in the presence of
high noise levels. Examples:
noisy restaurant, city street
Pulses blue every
10 seconds (when
latched closed)
Masks speech intelligibility at a constant
level of 90 dBA
Standard masking For use in the presence of low-to-
moderate noise levels. Examples:
quiet oce, residential area
Pulses white every
10 seconds (when
latched closed)
Adaptively masks speech intelligibility
up to voice levels of 90 dBA and speech
presence up to voice levels of 80 dBA
Standby In instances when audio masking
is not required or when needing to
conserve battery

To charge Vault with the lid open, insert the USB-C
side of the charging cable into the USB-C port and
then insert the USB-A side into a power source
(charge-capable USB port or wall charger) (Figure 13).

BATTERY LIFE
2+ days in Standard masking mode (in quiet
environments), ~6 hours in Maximum masking mode
• Standard audio masking mode: Utilizes adaptive
masking to automatically adjust masking signal
power levels based on ambient sound level. Quieter
environments consume less power while noisier
environments consume more. This mode maximizes
product battery life and minimizes masking signal
obtrusiveness.
• Maximum audio masking mode: Masking signals play
continuously at peak power. This mode enables users
to choose maximum protection, at a cost of shorter
battery life. Note, masking signals will be more
noticeable in this mode.
• Standby mode: No masking signal; battery status LED
pulses to indicate remaining battery life.
CHECKING BATTERY STATUS
Battery level will be indicated by the battery status LED,
with the color of the LED corresponding to the charge
level (Figure 14).
Battery status LED
Green = 60-100%
Amber = 20-60%
Red = 0-20%
Figure 14: Charge levels associated with battery status LED
Both the audio masking LED and the battery status
LED are visible through the LED status window when
Vault is latched closed. However, you can block these
LEDs if you’re trying to be covert or want to
eliminate light fatigue.
To cover the LEDs, toggle the LED cover switch so
that the LED status window is closed (Figure 15).

TESTING RF SHIELDING
With your smartphone inside Vault, you can try pinging your phone in a number of dierent ways (Figure 16).
Signal to test Smartphone settings Action Expected result
Cellular Cellular is turned on, WiFi is turned
o and the ringer is set to maximum. Call the smartphone. Your smartphone will not ring.
GPS Location services are turned on and
WiFi and Bluetooth are turned o.
Use a locator service (Like iPhone’s
Find My or Android’s Find My Device)
to locate the smartphone.
Your smartphone’s
location will be
unavailable.
WiFi WiFi is turned on, cellular is turned
o and the ringer is set to maximum. Call the smartphone. Your smartphone will not ring.
Bluetooth Bluetooth and Bluetooth sharing
are turned on.
From a compatible device, use the
Bluetooth sharing feature (like iPhone’s
AirDrop or Android’s Nearby Share)
to send the smartphone a photo.
Your smartphone will
not be discoverable.
While both the RF shielding and audio masking capabilities of Vault have been rigorously tested to ensure the
highest levels of protection, you may decide to perform informal tests to verify a baseline level of protection.
Figure 16: Sample RF shielding tests
Section 7: Testing Vault functionality
TESTING AUDIO MASKING
You can test audio masking using the following sequence:
Audio captured when Vault is latched closed should be masked by randomized noise.
1. Place your smartphone inside Vault.
2. Set the masking level to Standard or Maximum.
3. On your smartphone, start recording audio or video.
4. Latch Vault closed.
5. Introduce noise into your environment
corresponding to the masking level. For Standard
masking, you can speak at a conversational
volume; for Maximum masking, you can play
music at a loud volume.
6. Open Vault.
7. On your smartphone, stop the recording and then
play back the recorded audio.

• Cleaning: We recommend cleaning the gasket as
required, but no less than every 500 open/close
cycles (or every three months). To do so, apply
gentle pressure while wiping the surface of the
gasket with an alcohol wipe or a cotton ball/swab
dampened with isopropyl alcohol (Figure 17).
• Storage: We recommend turning masking to
Standby, and closing and latching the lid before
storing Vault. This helps keep dust/dirt from building
up on the gasket.
Section 8: Vault Care, Maintenance and Storage
Figure 17: Clean gasket
Gasket
To maintain the highest level of RF shielding, Vault’s gasket must be free of dirt and debris. To ensure that the
gasket remains clean, it’s important to follow the following recommendations:

CHARGING
Vault comes with a USB-A 3.0 to USB-C high-
speed charging cable. For optimal charging it is
recommended you use a Privoro Vault charging
cable. Vault has a maximum input current of 2.0A.
Using damaged cables or charging when moisture is
present can cause fire, electric shock, injury or damage
to Vault or other property.
