4 OVERALL FEATURES

2 CARACTERISTIQUES

4.1 TRANSMITTER BATTERY

Your transmitter is equipped with a NiMH battery ensuring optimum safety of use and a very reduced cost of ownership
of your set.
After reading the manual in its entirety, charge the Tx battery with a suitable charger (not supplied).
To perform this operation :
1/ Open the battery bay
2/ Get the free connector running out of the battery
3/ Connect the battery to the charger. We recommend to use the simple A2Pro 7200 or 7220 chargers.
4/ Once charging process is done, disconnect the battery from the charger.
6/ Replace the free connector in the battery bay and replace battery cover.
The battery of your transmitter, like any NiMH battery has a non negligible self-discharge rate. In other words, it will
i
discharge itself even if it is not used. It is therefore strongly recommended to charge at least once a month your
battery. Note that a new battery or one that has not been used for a long time should be properly charged before
use.
In addition, this type of battery suffers from a phenomenon called "memory effect" that occurs after a number of
recharge cycles-discharge incomplete. This reduces the lifetime and battery capacity. To limit this phenomenon, it is
recommended to follow this process :
 Totally discharge the battery
 Completely recharge the battery
Temperature strongly influences the characteristics of a battery when using it, but also during charging process.
!
Therefore, proceed to charge your battery in a room with an ambient temperature between 15 and 25 ° C.
Do not place or charge any of your NiMH batteries near a heat source or fire.
The NiMH battery supplied in your transmitter consists of elements containing chemicals. When the battery is
i
worn out, ie when its capacity will become too small, you will have to replace and remove the old battery into a
recycling center.
4.2 ANTENNA POSITION
The antennas used in the 2.4 GHz band are characterized by very short length (30 mm) as well as their important
directivity. This latter feature strongly influences the positioning of antennas of the transmitter and receiver.
To ensure optimum range of the link between the transmitter and the receiver, it is imperative to always fully deploy
transmitter antenna before flying. you should in no circumstances orient the antenna in the direction of the model
because the waves are less powerful in the axis of the antenna. In other words, antennas transmit and capture best
waves on the sides rather than their end.
The following diagram shows the directions in which the emitted waves are the most powerful, and therefore able to
ensure the best connection.
