ZEROTIME is an HD image transmission device. It contains an Air Set and a Ground Set, both of which are
compact and work smoothly with low signal transmission delay and high sending and receiving
sensitivities. ZEROTIME uses wireless links to transfer collected videos and images, flight control signals
and commands emitted from the Ground Set. ZEROTIME features a 2.4 GHz working frequency, low signal
delays (within 45ms), and long ranges of transmission (up to 2 km), and the device supports 1080P HD
video transmission.

Setup and Calibration
Linking
Keep the distance between the Air Set and the Ground Set between 1 and 2 meters. Connect both
Sets to power.
Press the Link Buttons on the Air and the Ground Sets for 3 seconds until the C-LED indicators
turn flashing green. Linking begins.
Linking is successul if the C-LED indicators on the Air and Ground Sets turn green.
ŀ
喆The Ground Set is linked to the Air set by default. Linking is required when a new Ground Set is used.
After linking an Air Set to a new Ground Set, the Air Set's previous linking to another Ground Set is automatically abolished.

ZEROTIME Video Transmission Settings

Channel Selection
The current video transmission data is illustrated graphically. Signal strength in each channel is
plotted. Channel settings may be done automatically (Auto) or they may be customized (Custom).
Video Resolution
The video quality can be set to 720P30, 720P60, 1080P30, or 1080P60. The default quality is
720P60.
Auto (default): When switched to Auto, the Ground Set selects the channel with the strongest
signal and adjusts the video transmission quality as distance changes.
Custom: When switched to Custom, video transmission channel and image quality are set
manually.
dž
dž
dž
dž
Image Bit Rate
Set the bit rate to adjust video transmission quality.
Note: The value of image bit rate must be smaller than that of the chanel bandwidth.
dž
Channel Bandwidth
Set the bandwidth to adjust video transmission quality. Small bandwidth corresponds to large
transmission distance and low image quality. Large bandwidth corresponds to small transmission
distance and high image quality.
Note: The value of the chanel bandwidth must be larger than that of image bit rate.
dž
OSD Settings
Enable on-screen display for flight information including altitute, distance, battery percentage,
photo/video switch, GPS satellite data, image signal strength, flight time, vertical speed, horizontal
speed, flying mode etc..
Users can add, remove or arrange icons on the display.

Firmware Upgrade
The way of upgrading the firmware of the Air Set or Ground Set is totally the same, let's take the Air
Set as an example.
Download the ZEROTIME setup package (ZEROTIME.zip) from ZEROTECH's official website
(http://www.zerotech.com).
Extract the package and save it to a USB storage.
ŀ
Step 1喟Before upgrading
ŀ
Ł
Use an OTG cable to connect the USB storage to the Firmware Upgrade Port on the Air Set. Turn
on the power for the Air Set.
The Video Transmission System automatically loads the firmware and installs the upgrade.
Upgrade is completed when the C-LED indicator is green.
