Installing dome

The SARAH2O PRO has a perspex dome that is ﬁtted to the front of the aircraft and is kept in place via

eight quick release, quarter turn clips. A complimentary micro ﬁber cleaning cloth and protective bag is

also provided.

A neoprene foam seal seated around the opening keeps the dome watertight.

To ﬁt the dome, follow the instructions below:

1. Move all of the clips to their open position

2. Using the supplied silicone grease, apply a thin later of grease over the dome neoprene seal

3. Place the dome onto the neoprene seal, ensuring it is seated evenly over the seal

4. Close the clips at apposing corners, e.g. bottom left, top right etc. Until all eight clips are in the

closed position

5. To remove the dome simply reverse the process

If you scratch the dome it is possible to remove marks by polishing them out using automotive/

car polish.

Place the aircraft upside down (on its back) to aid installing the dome.

Do not over tighten the clips.

You need to carry out a water test and adjust the clips on the dome before you ﬂy over water.

Please refer to page 13 for instructions.

SARAH2O PRO User Manual

Water test

Before you ﬂy over, or land on water, you will need to carry out a water test to ensure the dome and

rear hatch are ﬁtted and adjusted correctly.

Please follow the procedure below in order to carry out a water test;

Dome water test

1. Ensure the aircraft is powered o and the batteries are removed.

2. Remove the dome and rear hatch from the aircraft.

3. Using the supplied silicone grease, apply a thin later of grease over the dome neoprene seal.

4. Re-ﬁt the dome and ensure each retaining clip is in its closed position.

5. Lower the front of the aircraft into a suitable container ﬁlled with water (bath, tub, pool etc.) ensuring

all of the retaining clips are submerged - do not submerge the whole aircraft only the dome / dome

clips needs to be submerged.

6. After a few seconds you can lift the aircraft out of the water. Keeping the nose of the aircraft

pointing down, look through the opening at the rear of the aircraft to check that no water has

breached the dome. If any water has breached the aircraft you will need to adjust the retaining clips in

that area, so they apply more pressure to the dome / neoprene seal.

7. Once you have made any required adjustments, repeat the above process.

Rear hatch water test

1. Ensure the aircraft is powered o and the batteries are removed.

2. Remove the dome and rear hatch from the aircraft.

3. Using the supplied silicone grease, apply a thin later of grease over the rear hatch neoprene seal.

4. Re-ﬁt the rear hatch and ensure each retaining clip is in its closed position.

5. Lower the back of the aircraft into a suitable container ﬁlled with water (bath, tub, pool etc.) ensuring

all of the retaining clips are submerged - do not submerge the whole aircraft only the hatch / hatch

clips needs to be submerged.

6. After a few seconds you can lift the aircraft out of the water, keeping the nose of the aircraft

pointing up. Look through the opening at the front of the aircraft to check that no water has breached

the rear hatch. If any water has breached the aircraft you will need to adjust the retaining clips in that

area, so they apply more pressure to the rear hatch / neoprene seal.

7. Once you have made any required adjustments, repeat the above process.

Be careful not to get any water on the electrical components.

Only a thin layer of grease is required. Applying too much grease may cause it to run onto the

dome.

SARAH2O PRO User Manual

To adjust the clips

Hold the clip in the ‘closed’ position. Using the supplied 3mm hex key turn the screw clockwise, one

quarter turn at a time to increase the pressure against the dome / neoprene seal.

Repeat the water test process above until you have a watertight seal.

The dome and hatch on the aircraft use a neoprene foam seal, silicone grease and pressure to

make a watertight seal; this should be regularly checked for signs of wear or damage - for more

information please see the maintenance section on page 21.

Flight

Once pre-ﬂight preparation is complete, it is recommended that you use the ﬂight simulator to learn

how to ﬂy safely.

Ensure that all ﬂights are carried out in a suitable location.

You can then move to your ﬁrst ﬂight with the SARAH2O PRO - however we advise your ﬁrst few

ﬂights are carried out in ‘Beginner Mode’ which can be set via the DJI GO app. Beginner Mode puts

a Geofence around the aircrafts takeo point. It limits the maximum distance you can ﬂy to 30 meters

(98.4 feet) as well as restricting the height to 30 meters too. This can be turned o at anytime via the

GO app.

Gimbal motor error may occur in these situations: (1) gimbal is placed on uneven ground. (2)

gimbal has received an excessive external force, e.g. a collision. Please take o from ﬂat, open

ground and protect the gimbal after powering up.

Flight environment requirements

1. Do not use the aircraft in severe weather conditions. These include wind speed exceeding 12m/s and

lightening.

2. Only ﬂy in open areas. Tall buildings and steel structures may aect the accuracy of the on-board

compass and GPS signal.

3. Avoid obstacles, crowds, high voltage power lines and trees.

4. Minimize electromagnetic interference by not ﬂying in areas with high levels of electromagnetism,

including mobile phone base stations or radio transmission towers.

5. Aircraft and battery performance is subject to environment factors such as air density and

temperature.

6.Be very careful when ﬂying 14700 feet (4500 metres) or more above sea level as battery and aircraft

performance may be reduced.

7. The SARAH2O PRO cannot operate within the polar areas in “P” mode.

SARAH2O PRO User Manual

Pre ﬂight checklist

1. Before your ﬁrst ﬂight ensure you have completed a full bench test and followed the

instrucitons in this User Manual, including performing an Advanced IMU calibration and

Compass calibration.

2. Remote controller, aircraft battery, and mobile/tablet device are fully charged.

3. Arms are fully extended and locked into place.

IMPORTANT: Make sure to calibrate the compass before each ﬂight. The compass is very sensitive

to electromagnetic interference, which can cause abnormal compass data leading to poor ﬂight

performance or even failure. Regular calibration is required for optimum performance.

- DO NOT calibrate your compass where there is a chance of strong magnetic interference, such

as magnetite, parking structures, and steel reinforcements underground.

- DO NOT carry ferromagnetic materials with you during calibration such as keys or cellular

phones.

- DO NOT calibrate beside massive metal objects.

- YOU MUST calibrate your compass in every new ﬂight location - including your FIRST FLIGHT.

Calibration procedure

Choose an open space to carry out the following procedures.

1. Ensure the compass is calibrated. If you did not calibrate the compass when performing your

checklist, or if you have changed your position since the last calibration, tap the ‘Aircraft Status’

indicator bar on the DJI GO app and select ‘Calibrate” and follow the on screen instructions.

2. Hold and rotate the aircraft horizontally 360 degrees anti-clockwise, and the Aircraft Status

Indicator will display a solid green light.

3. Hold the aircraft vertically with the nose pointing downward, and rotate 360 degrees anti-

clockwise, around the center axis. Recalibrate the compass if the Aircraft Status Indicator shows

solid red.

If the Aircraft Status Indicator blinks red and yellow after the calibration, move your aircraft to a

dierent location to carry out compass calibration.

Calibrate the compass before each ﬂight.

SARAH2O PRO User Manual

When to recalibrate

1. When compass data is abnormal, and the Aircraft Status indicator is blinking red and yellow.

2. When ﬂying in a new location, or a location that is dierent to your last ﬂight.

3. When the mechanical structure of the aircraft has changed, i.e. changed mounting position of the

compass.

4. When severe drifting occurs in ﬂight, i.e. the aircraft does not ﬂy in straight lines.
