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.
A 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.
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.
