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.
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.
