39 Using the transmitter for the first time - Updating the firmware
ently using them incorrectly. This means that any
servos connected to these channels will simply
“stay put” at their centre position until a trans-
mitter control is assigned to the channel in ques-
tion. For the same reason virtually all the mixers
are inactive by default. For more details of this
please refer to page 86 (fixed-wing model) or 88
(helicopter).
The basic procedure for programming a new
•
model memory can be found on page 66, and in
the programming examples starting on page 164.
When switching on, binding or setting up the ra-
•
dio control system, please ensure at all times
that the transmitter aerial is an adequate distance
from the receiver aerials. If the transmitter aeri-
al is too close to the receiver aerials, the receiver
will be swamped, and the red LED on the receiv-
er will begin to glow. At the same time the down-
link channel will stop working. As a result the
field strength bars on the transmitter screen are
replaced by “x”, and the receiver battery voltage
is displayed as 0.0 V. At the same time the radio
control system switches to Fail-Safe mode, see
page 136, i.e. the servos remain fixed in their cur-
rent position for as long as reception is not pos-
sible, and until a new, valid signal is picked up.
If this should happen, simply increase the dis-
tance between transmitter and receiver until the
displays revert to “normal”.
Updating the transmitter firmware
The transmitter firmware can be updated at the owner’s
risk using either of two methods:
As described under “FIRMWARE UPDATE / Chang- •
ing the screen language” in the section entitled
“
Hidden mode ” on page 27.
As described in the next section, using the five-pin •
mini-USB port on the back of the transmitter, in
conjunction with a PC or laptop running Windows XP,
Vista or 7.
