AFETY NOTES
! Read the instructions before using the module.
! Do not modify the module. Unauthorised work on the
module invalidates the transmitter's operating approval.
If the settings of any components are changed, or if the unit is
damaged, send the module to your nearest MULTIPLEX Ser-
vice Centre for checking.
! Protect the module from mechanical stress (vibration,
shock, distortion) when stored. Protect it from damp, and
store it in a protective ESD bag designed for electronics.
! Always switch the transmitter off before opening the
case. Never carry out any work inside the transmitter
with the power turned on.
Disconnect the transmitter battery to be on the safe side.
3. ESD
NOTES
Electronic devices are sensitive to electrostatic dis-
charge. This module also contains components
which can be damaged in this way. The damage
can occur when charged components dissipate their
charge (potential imbalance), typically when the
components are touched. This can also shorten the compo-
nents' effective life. The module is supplied in a conductive ESD
bag which provides effective protection from this risk.
It is important to observe the following safety measures when
handling modules which are subject to electrostatic damage:
•
Earth yourself before fitting the module or removing it from
the transmitter. This can be done by touching a radiator or
similar earthed metal object with your hand.
•
Open the transmitter (if necessary), and hold it by a large
area in order to allow any potential differences to dissipate.
•
It should now be safe to remove the module from the con-
ductive ESD protective bag. Avoid touching the electronic
components or solder pads directly. Hold the module only
by the edges of the circuit board.
•
When the module is out of the transmitter, store it in the
conductive ESD protective bag at all times. Never allow it to
contact ordinary, non ESD-suitable foam plastic, styrofoam
or other plastic material.

band EATURES
The Channel-Check PLUS module has two basic functions:
•
Channel-Check
Automatic protection from channel clashes (two transmitters
on the same frequency) when you switch on the transmitter
•
Manual scan
Signal strength display (showing channels in use) with man-
ual channel selection (3D digi-adjustor)
When you switch the transmitter on, the Channel-Check func-
tion automatically checks whether the set channel is free before
it allows the RF module to be activated. The transmitter only
starts transmitting if the set channel is found to be vacant (not
already in use); an RF signal is then transmitted. This represents
an important contribution to safety when flying model aircraft, as
it considerably reduces the risk of crashes due to channel
clashes.
Manual Scan mode allows the user to check the transmitter's
frequency band. The signal strength is shown on the screen in
four stages in place of the usual trim display. The Channel-
Check PLUS module works like a normal radio control receiver.
No RF signal is radiated during scanning operations.

ITTING THE
! Note: identical frequency band
The frequency band of the Channel-Check PLUS module
must be identical to that of the transmitter!
You will need to open the transmitter case in order to install the
Channel-Check PLUS module; the procedure is described in de-
tail in the COCKPIT SX operating instructions (undo the seven
TORX screws in the back of the transmitter).
! Read the ESD notes (
The module is simply plugged into the main circuit board of the
COCKPIT SX.
Carefully fit the Channel-Check PLUS module in the transmitter,
then close the transmitter back and fit the screws again.
The Channel-Check PLUS module is now ready for use.
