Spektrum SPMR9900 DX9 - Manual (Page 5)

5 SPEKTRUM DX9 • TRANSMITTER INSTRUCTION MANUAL
EN
The DX9 has an internal charger designed to charge the included
2-cell Li-Ion 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 DX9
transmitter. If you wish to charge the Li-Ion battery using a Lipo/
Li-Ion charger, you must remove the battery from the transmitter
before charging.
The first 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
appropriate 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 voltage
limit (4.3V for NiMH, 6.4V for LiPo/Li-Ion).
CAUTION: Never change the low voltage limit for
LiPo/Li-Ion batteries from 6.4V. Doing so could over-
discharge the battery and damage both battery and transmitter.
