Charging Your Transmitter; Nimh/Lipo Battery Support; Battery And Charging Precautions And Warnings - Spectrum DX8 Instruction Manual

ChARGING YOUR TRANSMITTER

The DX8 features a built-in multi-chemistry charger designed to charge 4-cell
NiMH and 2-cell LiPo batteries at a charge rate of 200mAh. The charge jack on
the right side of the transmitter is non-polarity-critical, allowing you to use any
type of 12-volt supply to charge the battery regardless of connector polarity.
Using the included SPMB2000NMTX NiMH battery pack, you should plug the
included 12-volt AC to DC power supply in for 10 to 12 hours to fully charge
the battery.
CAUTION: Never plug in a peak detection or fast charger into your
DX8 as this could damage the internal charge circuit. Use only a 12V DC
source.
With the transmitter power turned off, plug the included 12 volt power supply
into a wall outlet. Then plug the male charge plug into the charge jack. The blue
LED on the front of the transmitter will illuminate. When charging the optional
SPMB4000LPTX, a full charge can take up to 30hrs depending on the initial
charge state of the battery. When charging a LiPo, the blue light will turn off
when the charge cycle is complete.
SPEKTRUM DX8 • RADIO INSTRUCTION MANUAL

NIMh/LIPO bATTERY SUPPORT

The DX8 includes a rechargeable NiMH battery pack. A low battery alarm
sounds when the battery reaches 4.3 volts. Spektrum offers an optional 2-cell
LiPo battery pack (SPMB4000LPTX) for the DX8. LiPo batteries have a higher
operational voltage and when switching to a 2-cell LiPo battery in the transmitter,
it is important to change the low battery alarm to the LiPo setting to prevent
over-discharging the pack.
To Access and Change battery Type
In the System Setting screen (see page 20 in your manual) rotate the roller to
select NEXT at the bottom right of the System setting screen. The following
screen appears.
Rotate the roller to highlight battery type.
Press the roller to access NiMH or LiPo. The low voltage cutoff will default to
the recommended voltage for the battery type selected. The voltage cutoff can be
adjusted from this screen, but normally the default cutoff of 6.4 volts for LiPo is
recommended.
