TELLO

User Manual

f. Flying in an area where the lighting changes frequently or drastically.

g. Flying over extremely dark (< 10 lux) or bright (> 100,000 lux) surfaces or towards

bright sources of light (e.g. towards sunlight).

h. Flying over surfaces without clear patterns or texture.

i. Flying over surfaces with identical repeating patterns or textures (e.g. tiling).

j. Flying over small and ne objects (e.g. tree branches or power lines).

k. Flying at speeds of over 11 mph (18 kph) at 3.5 ft (1 m) or lower.

• If the aircraft's Vision Positioning system fails for 3 seconds when its ying altitude is

above 20 ft (6 m), Failsafe Protection will automatically initiate landing. If the Vision

Positioning system recovers during landing, Failsafe Protection will shut off and the

aircraft will hover.

• The Vision Positioning System may not be able to recognize patterns on the ground in

very dark (< 100 lux) environments. DO NOT take off if there is a warning prompt in the

Tello app telling you that the environment is too dark.

• Keep the cameras and sensors clean at all times. Dirt or other debris may adversely

affect their effectiveness.

Intelligent Flight Modes

The Tello features Bounce mode, 8D Flips, Throw & Go, Up & Away, and EZ Shots. To use an

intelligent ight mode, ensure that the aircraft’s battery level is at least 50%, tap in the Tello app,

then select a mode.

Bounce Mode

In Bounce mode the aircraft automatically ies up and down between 1.6 and 3.9 ft

(0.5 and 1.2 m) above a at surface. If the aircraft detects an object below it (such

as your hand) it increases its altitude then continues ying up and down.

Using Bounce Mode

1. Press the power button once to turn the aircraft on. Launch the Tello app and

tap to take off.

2. Tap and then select Bounce mode. Read the information prompt and then select

Start

. The

aircraft will start ying up and down.

3. Extend your arm and place your palm 1 ft (30 cm) or more below the aircraft, keeping your palm

open. The aircraft will increase its altitude then continue ying up and down.

4. Tap in the Tello app any time to exit Bounce mode.

• Ensure there is sufcient space when using Bounce mode. Allow a radius of at least 7 ft (2 m)

horizontally around the aircraft and allow at least 10 ft (3 m) above the aircraft.

• Before using Bounce mode ensure that the Aircraft Status Indicator is periodically blinking

green twice, indicating that the Vision Positioning System is available.

• In Bounce mode, ensure your arm is extended and your palm is at. DO NOT try to

catch the aircraft. The distance between your palm and the aircraft should be at least 1

ft (30 cm).

• Watch out for potential obstacles in your surrounding area (especially on the rear, left, and

right sides of the aircraft) and stay clear of them to avoid accidents.
