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 DX7s includes a rechargeable NiMH battery pack. The DX7s
has 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 port on the right side of the transmitter is not
polarity-dependent.
CAUTION: Never connect a peak detection charger or fast
charger to your DX7s. These devices can damage the internal
charge circuit. Use only the included 12V DC source.
Charge in a safe place NOT affected by the usual heat that
comes from a charger and batteries during charging.
1. Power off your transmitter.
2. Connect the power supply’s connector to the transmitter’s
charge port.
3. Connect the included 12-volt power supply to a power outlet
using the appropriate outlet clip.
4. The blue LED on the front of the transmitter will illuminate
during charging.
5. The blue LED will remain lit when charging the included
NiMH battery. When charging the optional LiPo battery the
blue LED will go off when charging is complete.
6. Disconnect the transmitter from the power supply when
charging is complete.
7. Disconnect the power supply from a power outlet when the
power supply is not in use.
For first use, charge the included NiMH battery pack for 10 to
12 hours until fully charged. Use the included 12V power supply.
If you purchase the optional LiPo battery pack (SPMB4000LPTX),
the initial charge can take up to 30 hours.
CAUTION: Never leave a charging battery unattended.
Battery Alarm
The System Settings Screen allows you to change the battery
type and low alarm settings.
• Always set the Battery Type to correspond with the chem-
istry of battery that is installed to enable the correct low
voltage limit. When using a LiPo battery, you must connect
the battery to the transmitter and then change the battery
type in the programming. See Appendix for LiPo battery
pack installation.
• 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.
