Reely SKY Jet Ranger Notice D'emploi page 36

When new batteries or freshly charged rechargeable batteries have been inserted, switch on the transmitter with the
function switch (see figure 1, item 5) for test purposes. The green LED display (see figure 1, item 8) indicates the
power supply of the transmitter.
If the power supply is not sufficient any more for faultless operation, the LED colour switches to yellow. In this case,
you should stop operating your model as quickly as possible.
If the voltage drops below 7.5 V, the LED colour turns red. To continue operating the transmitter, recharge the batteries
or insert new batteries.
