INTRODUCTION
Mounting Sentry
Sentry, Sentry Mini, and Sentry Plus can be mounted with the provided RAM mount. RAM
mount includes a quick release that allows you to detach the receiver while leaving the mount
in place. For best results, mount your receiver vertically on a side window where it can have an
unobstructed view of nearby aircraft and ADS-B ground towers.
If no windows are available, place the receiver on a level, flat surface with the LED indicators
facing towards the nose of the aircraft. Aircraft structure can block weather and traffic signals.
If traffic targets are missing from ForeFlight or if you’re unable to receive ADS-B weather, try
moving the receiver in the cockpit to obtain a better signal.
Do not leave your receiver or the mount in an aircraft for extended periods of time when
temperatures are expected to exceed 90º F.
To mount Sentry, Sentry Mini, or Sentry Plus,
1. Place the RAM mount on the window with the screws aligned vertically and
rotate the tabs on opposite sides of the mount clockwise until they snap into
place.
2. Attach Sentry to the RAM mount by aligning the quick release adapter on the
rear of the unit with the slot in the RAM mount. Rotate the receiver clockwise
until it snaps in place.

INTRODUCTION
Connecting to Sentry
Whether you’re connecting to Sentry, Sentry Mini, or Sentry Plus, start by powering the device
on. Sentry and Sentry Plus can be powered on by holding the power button for approximately
two seconds until the LEDs illuminate. Power Sentry Mini on by connecting the provided USB-
C cable to a 5 volt, 2 amp power source.
Once powered on, Sentry receivers create their own
wireless network. Open your iPad or iPhone Settings
app and select Wi-Fi.
Locate Sentry’s wireless network in the Other
Networks section and tap to connect.
Once the iPad or iPhone is connected to Sentry,
open ForeFlight Mobile and select More > Devices to
ensure the Sentry tile appears. If the Sentry tile does
not appear, verify the Wi-Fi connection and ensure
Local Network settings are enabled.
Local Network Setting
Devices with iOS 14 or later require special permission to connect to external devices like
Sentry. If Sentry does not appear in ForeFlight, open the iPad/iPhone Settings app and select
ForeFlight from your list of installed apps. Verify the Local Network Setting is enabled.

INTRODUCTION
Firmware Updates
Sentry firmware updates are provided by ForeFlight.
If updated firmware is available for your Sentry,
Sentry Mini, or Sentry Plus, ForeFlight will prompt
you to update the firmware. If you do not receive a
prompt to update your firmware, ForeFlight has
determined you already have the latest firmware
installed.
If a firmware update is postponed, ForeFlight will not
prompt you to update the next time you connect.
Postponed firmware updates can be accessed from
the Sentry Device page by selecting More > Devices
and tapping the Sentry tile.
Sentry and ForeFlight must remain on while firmware is updated. As firmware is being
updated, ForeFlight displays a progress bar. Firmware update typically take less than a minute
to install.
