Introduction
Congratulations on purchasing the Fat Shark Dominator VGA FPV video
goggles. To ensure your continued enjoyment, please take the time to read
through this operating manual thoroughly before using.
Product Compatibility
The Dominator has been designed to adhere to established video standards
and is compatible with any product also adhering to accepted video
standards. Due to the high number of different manufacturers and variation
in quality, it’s impossible to for us to have tested with every product
combination and some troubleshooting may be required if mix/matching
components. The Dominator has been thoroughly tested with ImmersionRC
gear. For best results and no compatibility issues, Fat Shark recommends
ImmersionRC gear for your accessory products.

Powering options
If multiple power sources are supplied at same time (i.e. Futaba radio
and head strap battery) the headset will draw power from the highest
voltage.
Futaba Radio
The Dominator can be powered off a
Futaba radio via the Data Cable.
Note: Best to upgrade the Futaba
radio to a 3S 2200mAh radio lipo
pack for this type of connection as
the headset will cause extra drain on
the transmitter battery pack. A
normal NiMh radio battery will not
have sufficient battery life for safe
flying.
Base Station
Use the AV cable to connect
the video/audio.
AV cable has Y splitter with
male and female DC head to
share power with the external
RX supply (up to 13V).
Battery
The Dominator can be
independently powered via an
external battery pack (see
accessories for 1000mAh 7.4V lipo
pack with specially molded case
for sitting in head strap pocket).
Note that the battery will only
supply power if no other higher
voltages sources are connected.

Futaba Radio setup.
Note: Head tracker only works with higher end Futaba radios that support
selective student channel mixing. Connect Data cable and turn on radio.
- Enter TRAINER menu and assign desired head tracking channels to
FUNC (must be set on FUNC). Default is CH 5//6.
- Individual servo direction can be set in REVERSE menu (reverse
not available for 7C users, must reverse direction in HT menu).
Head Tracker Operation
- Head tracker will automatically start tracking upon powering up headset.
- Look forward and level then press the Head Tracker button to center (note,
on 1
st
press HT may drift off momentarily during calibration cycle, hold head
steady until camera returns to center).
- Repressing the HT button during use re-centers the camera position.
- External interference (from RC controller, other devices) may temporarily
cause errant readings in the magnetic sensor and cause drift. If error
between camera and direction your head occurs, hold your head steady in
one position and head tracker will autocorrect to that position.
After auto correction, continue to use normally.
Head Tracker Center Hold Function
To pause and hold head tracker in center position; hold down the HT button
for 4 seconds (4 seconds to pause, 4 seconds to reactivate).

orientation not critical.
Battery and Charger
The 1000mAh 7.4V lithium polymer
battery pack can power the headset
for up to 4hrs in direct mode and
2.5hrs in wireless mode. Internal
safety circuit monitors charging and
prevents accidental over drain. The
molded curved ends hold the battery
snug in the head strap pocket.
Charging Instructions
When the charger is plugged in with
no battery attached, the LED will be
GREEN. When you connect the
battery the LED will turn RED
(charging). When fully charged, the
LED will turn back to GREEN. The charger will automatically stop charging
when the battery is fully charged. Do not leave plugged in while unattended.
DO NOT LEAVE BATTERY ATTACHED TO CHARGER WHEN
CHARGER IS NOT PLUGGED IN.

· For best performance, select a channel that has the least amount
of interference. While the transmitter is turned OFF, turn on the
video headset and look at the screen as you check each channel.
Clear channels will have a consistent static background. Channels
with interference will have horizontal static lines.
· Always perform a range test before flying. This includes AV and
RC controls. Some RC receivers can be affected by the proximity
of other electronic devices particularly the AV TX.
· Try to space out your components as much as possible to avoid
interference to your RC control range (keep stuff away from RX)
· Do not use 2.4Ghz AV with 2.4Ghz RC controllers.
· Your 2.4Ghz TX will not affect the RC control of other RC users
(however, their controllers will affect your AV reception).
· Be aware of other 2.4Ghz RC users. If they turn their RC radio
nearby, they may knock out your image.
· Until experienced, practice flying in a familiar area to avoid
becoming disorientated.
· Due to antenna characteristics, there is a “null” in line with antenna
direction. You may experience excessive video breakup when flying
overhead
· 5.8Ghz signal strength drops off very fast (2.4Ghz is more gradual).
If using 5.8Ghz, stay safely within solid AV range.
· For maximum distance it is very important that a clear line of sight
exists between the transmitter and the video headset. 2 of the worst
causes of interference are human bodies and reinforced concrete.
· Place your TX antenna in open area in a vertical orientation
· Multipathing (reflections off buildings/ tall objects) causes signal
cancellation and result in broken video. Fly in open areas away
from buildings or other tall structures (i.e. barns, hills).
· The headset may become warm to touch during use particularly in
the top center region. This is normal. If you are unsure, run the
headset for 30 minutes fully powered before flying to ensure normal
operation.
· 5.8Ghz AV with 2.4Ghz RC controllers: 2.4Ghz may cause
harmonic interference on Ch2 – Ch7 of the 5.8Ghz AV (Ch1 not
affected). The headset has been equipped with a high pass filter
that will allow the system to work with CE certified 2.4Ghz RC
controllers. However, the filtering may be insufficient to remove
noise from overpowered non CE certified controllers.
If you experience interference from your RC radio, change the AV
channel to channel 1.
· Although you don’t require any license to operate this device, you
are still legally responsible for operating in a responsible manner.

2.4Ghz receiver
- Choose a cleaner channel.
- Change to 5.8Ghz AV
- Check correct frequency antenna is used
Lots of interference lines
(horizontal lines) when
using 5.8Ghz receiver
Check to see if cause is harmonic interference
from 2.4Ghz RC controller (turn radio on/off).
- Use CH1 on TX/headset (Ch1 not affected
by 2.4Ghz)
- check correct frequency antenna is used
Head tracker not working - Ensure module pins are aligned correctly
into headset socket
- Review controller manual for correct settings
- Check servos are plugged into
correspondingly selected channels
Short range - Ensure correct antenna are installed
- Check for other sources of interference
- Ensure transmitter has clear LOS to
headset. Test in wide open area, away from
any obstructions
Short range (con’t) - Ensure that a compatible antenna is
installed. 2.4Ghz must use a 2.4Ghz antenna
and 5.8Ghz must use a 5.8Ghz antenna
- do not use other manufacture antenna, they
may be dual band or may be reverse SMA (no
center pin to connect to receiver)
