To install the battery the back panel must first be removed as
follows: push the two latch sliders outwards for a distance of
about 2 cm as shown in Fig. 2. The back panel can now be
lifted off forwards under light pressure. Check that the aerial
does not fall out of its holder when you do this.
F-14's voltage indicator
The LED voltage indicator shows the voltage of your transmitter battery by means of various LED sequences.
1 ) Two LEDs light up:
Voltage 9.2 V or more. Battery capacity bet-
ween 100 and 30%.

Fig. 3 shows an internal view of the transmitter. Place the bat-
tery in the recess provided for it; the back panel will hold it in
place securely. Deploy the cable from the battery to the circuit
board as shown, and push the socket firmly onto the appro-
priate pins. The connector is polarised, i.e. it can only be con-
nected the right way round.
Close the transmitter by reversing the procedure described
above. Note that the transmitter back panel should first be en-
gaged at the front, then at right and left.

Operating times

With a 1400 mAh battery the transmitter will operate for about
6 hours. If you fit a 2000 mAh battery the maximum operating
time rises to about 8 hours. Please note that this does not apply
to the receiver battery. The receiver battery's operating time
varies greatly according to the number of servos connected
to it, the freedom of movement of the control linkages, and the
frequency of control commands.
For this reason it is very important to ensure that all mechanical
linkages move freely, and that the servo is not mechanically
obstructed or restricted at any point in its travel.

Charging the batteries

We recommend that you also use a factory-made battery pack
for the receiving system. Glow motors can cause vibration in
the model, with the resultant danger of loss of control due to
intermittent contact, and welded or soldered packs eliminate
this problem. When the receiver battery is almost discharged
you will notice that the servos run markedly more slowly.
