Battery and Charging Precautions and Warnings
Failure to exercise caution while using this product and comply with the following warnings could result in product malfunction,
electrical issues, excessive heat, FIRE, and ultimately injury and property damage.
Charging Your Transmitter
The DX18 has an internal charger designed to charge the
included 2-cell LiPo battery at a charge rate of 200mAh. The
charge port on the right side of the transmitter is not polarity-
dependent.
NOTICE: Never connect an external battery charger to your
DX18 transmitter. If you wish to charge the LiPo battery using a
LiPo charger, you must remove the battery from the transmitter
before charging.
The fi rst time you charge the transmitter battery, the charge time
may be 12-15 hours. Always charge the transmitter on a heat
resistant surface.
1. Power off your transmitter.
2. Connect the power supply connector to the transmitter
charge port.
3. Connect the power supply to a power outlet using the appro-
priate adapter.
4. The blue LED on the front of the transmitter turns on during
charging and turns off when the battery is fully charged.
5. Disconnect the transmitter from the power supply once
charging is complete and disconnect the power supply from
the power outlet.
CAUTION: Never leave a charging battery unattended.
LED indicators
The blue LED indicates the transmitter battery is charging. The
orange LED indicates the transmitter is powered on and there is
radio transmission.
Battery Alarm
The System Settings Screen allows you to change the battery
type and low alarm settings. See “System Settings” for more
information.
• An alarm will sound when the battery reaches the low volt-
age limit (4.3V for NiMH, 6.4V for LiPo).
CAUTION: Never change the low voltage limit for LiPo
batteries from 6.4V. Doing so could over-discharge the
battery and damage both battery and transmitter.
