How to Place Transmitter Antenna Right
DA16s transmitter antennas have the best signal strength when they are placed horizontally. Thus, please
avoid pointing antennas’ upper end directly to aircraft.

Foxtech DA16s Radio Control System User Manual
©2018 FOXTECH All Rights Reserved 12
Do not fold or cover antennas and avoid any obstruction between transmitter and aircraft in a flight,
otherwise there will be an obvious decrease to transmission signal strength.
DA16s transmitter is equipped with a built-in 3000mAh Li-Po 1S battery. Charging time is generally
between 2.5 to 3 hours using a standard 5V/2A adapter charger. Charging time may be different using
charger with different standards, please pay an attention to transmitter charging indicator in charging.
Each unit of DA16s transmitter is assigned with a unique ID code. Before linking DA16s receiver to DA16s
transmitter, receiver must identify transmitter ID(Linking). After the first linking between transmitter and
receiver, the ID code will be memorized in receiver, so that you don’t have to repeat linking next time (except
if the transmitter was linked with a different receiver after that).
Before charging DA16s transmitter, please read the part “READ TIPS - Precautions on Charging DA16s
Transmitter” in this manual carefully.
Transmitter charging time is limited by charger’ power output. More power charger adapter has, less
charging time it is.
(1) Choose the right charger for DA16s transmitter;
(2) Make sure that DA16s transmitter is powered off.
(3) Find a Micro-USB cable among accessories
coming with DA16s transmitter packaging, connect
its Micro-USB end to transmitter’s Micro-USB port on
the back, USB end toadapter charger;
(4) Plug charger into adapted AC power outlet;
(5) In charging, transmitter charging indicator is solid
red; charging finished, it turns to solid green.
