The RF-Flight Recorder display is accessed by briefly
and simultaneously pressing buttons I and II on the
SensorSwitch:
Antenna Fades: - Spektrum, Futaba, M-Link: This item displays the lost data packets for the individual recei-
vers.
- HoTT and Jeti: This item displays the number of switching events between the receivers.
Lost Frames: This value shows how many occasions none of the connected receivers was able to supply a
valid data packet.
Holds: This value is incremented when none of the connected receivers is able to supply a valid signal
for a period longer than 250 ms. When this occurs, the servos move to the Hold or Fail-Safe
positions stored in the backer.
The Power-Flight Recorder display can be accessed
by briefly and simultaneously pressing buttons I and II
on the SensorSwitch a second time:
This Flight Recorder enables you to monitor all data relating to current and batteries
- Min. Voltage: This is the lowest value to which your battery voltage fell during the flight.
- Max. Current: The highest current which was drawn from each battery during the flight.
- Consumption: This item shows the energy consumed since the system was last switched on. The value is
erased when you switch the system off.
Note: it is extremely rare for the maximum current and / or energy consumption of both batteries to be
identical. In fact, the discrepancy is proof that the backer exhibits "genuine redundancy", i.e. it contains two
systems which work entirely independently of each other. Although we go to great lengths to match the inte-
gral regulators accurately to each other, there are always minor manufacturing tolerances in the components,
hence the difference. Only non-redundant systems drain the batteries equally.

3. INITIAL STEPS

a) Installation notes
The four mounting holes in the base plate of the PowerBox Champion SRS are fitted with rubber grommets as
standard. The Champion SRS should be mounted on a surface which is not subject to serious vibration, using
the retaining screws supplied in the set. Although all PowerBox products are designed to be highly resistant to
vibration, you should still avoid attaching the backer to thin GRP or CFRP surfaces.
The internal card packaging can be used as a template for installing the SensorSwitch. The SensorSwitch
should also be installed at a point where vibration is low. The GRP fuselage sides of a powered model aircraft are
not suitable for this, as they suffer from severe vibration. The appropriate area should be stiffened with a piece of
plywood 2 to 3 mm thick; 20 to 40 mm of wood round the switch is generally sufficient to stiffen the GRP fuselage
side. Gluing the plate to the GRP material helps to absorb the vibration, and also provides plenty of "meat" for the
switch retaining screws.
The Info Display should also be installed at a point where vibration is low – and ideally in a position where it can
be seen clearly. The Info Display does not need to be left permanently in the model, as the Champion SRS also
functions without the screen connected. All you have to do is ensure that it can be plugged into the main unit
when you are using the system.
Connect the SensorSwitch, the Info Display and your batteries to the PowerBox. The Champion SRS features
unrestricted output mapping. This means that you can assign any function to any of the output. For this reason
you should not connect the servos until later – see point 3d.

b) Switching the PowerBox on, the menu system

The method of switching on and off is very simple, and effectively prevents the system being switched on or off
accidentally. This is the procedure: locate the SET button on the SensorSwitch and hold it pressed in until the
centre LED lights up red. Now press the two buttons I and II in turn: the backer is now switched on. The procedure
for switching off is exactly the same: hold the SET button pressed in, wait until the centre LED lights up red, then
switch off by pressing buttons I and II in turn.
Your PowerBox stores the last switched state. This means that the backer stays off if it is switched off using the
SensorSwitch. Once switched on, the unit can only be switched off again using the SensorSwitch. Any intermit-
tent contacts or interruptions in the power supply circuit cannot cause the backer to be switched off.
The menu system for all PowerBox devices is as simple as possible, and generally self-explanatory:
- Hold the SET button pressed in for a few seconds to access the menu system.
- Use the SET button to select the menu point you wish to use.
- Buttons I and II are now used to move the cursor up or down, and to change values once a menu point has
been selected.
- Pressing the SET button again leaves the menu point.

c) Setting the receiving system to be used

The first requirement is to define the receiving system.
If this setting is not selected, the subsequent func-
tions, settings and assistants only work in a restricted
manner.
Switch the PowerBox on as described above. Hold
the SET button pressed in for a few seconds, and the
menu system appears. Select the RX/TX SETTINGS
point; the first point in the TX-SYSTEM menu enables
you to select your radio control system:
