Battery Safety
CAUTION
Protect batteries from dust, moisture, heat and vibrations.
For use in dry locations only.
Do not use damaged batteries.
Batteries not handled properly may catch fire, explode, or
cause irritation and burns. To extinguish a battery fire use
either water, CO² or sand.
Batteries should not be heated, burned, short-circuited,
incorrectly inserted, modified, soldered or welded.
Charge batteries in a room outfitted with a smoke detec-
tor, on a non-flammable, heat-resistant and non-conductive surface. Keep away from combustible or highly flammable objects while charging. Always monitor batteries
during the charging process.
Do not exceed the maximum quick-charging current
specified for the respective cell type.
If a battery reaches temperatures above 140°F (60°C)
while it is being charged, immediately stop charging and
let the battery cool down to approximately 86 - 104°F (30
- 40°C).
S1008_X-8E_jh_V1
Never charge batteries that have already been charged,
are hot or are not fully discharged. If a cell in a battery pack
heats up following a quick-charge process, this may indicate a defective cell. Discard the battery immediately!
9 / 48
Damaged or corroded batteries may leak an electrolyte
that is caustic and should not be touched or come into
contact with your skin or eyes. In case of emergency,
rinse thoroughly with water and seek immediate
medical attention.
Always fully recharge the battery.
Special instructions on charging LiPo batteries
To charge and discharge LiPo batteries, only use specifi-
cally designed chargers/dischargers with balancer connector.
The white connector (cell count + 1 pole) is designed for
the connection to a LiPo balancer or a battery charger as
a single cell charger with a manual cell balancer. Always
charge the battery with the balancer connector.
Safety notes for stocking LiPo batteries
LiPo batteries should be stored with a voltage of about
3.8V per cell. If the cell voltage falls below 3V, then the battery must be charged. Fully discharging or storing a battery with a cell voltage < 3V renders the battery useless.
Exersize safety procautions when charging and transport-
ing your LiPo batteries. Always use a safety bag.

the cover and ensure it is securely closed.
On - Off
Switch
Set the the battery warning threshold in accordance with the
battery used. (see Chapter “SYS SET”)
If a voltage warning is triggered, charge the batteries.
Battery charging
Charge the LiPo batteries in the transmitter through the micro
USB socket using the USB cable provided. For all other battery
types, use an USB connection, e.g. a PC USB port or an USB
net adapter. During the charging process the LED under the display lights up red. When the battery is full the LED turns off.
Alternatively, you can charge the battery outside the transmitter
with an RC battery charger (not included).
Transmitter power switch
On the top of the transmitter there are two buttons. To turn on
the transmitter with RF off, push the right button for about 2 seconds. When the RF mode is off, a safety feature is activated that
prevents switched-on models from accidentally starting during
programming. Additionally, power consumption is reduced,
significantly conserving battery life.
