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 rst 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.
