Charging
For optimum charging results, the built-in charger requires a
USB power supply capable of at least 2-3A output. Using a
power supply with a lower output will result in very long charge
times or the transmitter not charging if it is powered on while
attempting to charge.
The fi rst time you charge the transmitter, the charge time
may be 6-7 hours. Always charge the transmitter on a heat-
resistant surface.
Charging:
1. Connect the power supply (not included) to an AC outlet.
2. Connect the Micro USB cable to the power supply and to
the charge port on the transmitter as shown.
3. The LED will fl ash blue while charging. A fast press of the
power switch will bring the Charge Battery icon to the color
touch screen display.
4. Charging is complete when the blue fl ashing LED stops.
Disconnect the USB cable once charging is complete and
disconnect the power supply from the power outlet.
• Never charge batteries in extremely hot or cold places
(recommended between 50–80˚ F or 10–27˚ C) or place
in direct sunlight
• Always disconnect the transmitter after charging, and let
the charger cool between charges
• Always inspect a new battery before charging
• Always terminate all processes and contact Horizon Hobby
if the product malfunctions
• Always keep batteries and charger away from any material
that could be affected by heat (such as ceramic and tile),
as they can get hot
• Always end the charging process if the charger or battery
becomes hot to the touch or starts to change form (swell)
during the charge process
CAUTION: Never leave a charging battery unattended.
CAUTION: Never change the low voltage limit for Li-Ion
batteries below 3.3V. Doing so could over-discharge the
battery and damage both battery and transmitter.
CAUTION: Never charge the battery outside of the
transmitter. Charging the battery outside of the
transmitter may interfere with the battery monitoring
system, which can give false low battery warnings.
