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 first time the transmitter is charged, the charge time may be
6-7 hours. Charge the transmitter when the low battery alarm
sounds. See the System Settings section for information on setting
the low battery alarm level.
Always charge the transmitter on a heat-resistant surface.
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 leave a charging battery unattended.
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.

2. Connect the included magnetic USB charging cable to the
