1. 8 Guarantee conditions During the production process each battery backer undergoes a series of tests We take the maintenance of the highest quality standards very seriously and that is why we are able to grant a 24 month guarantee on all our battery backer systems valid from the initial date of purchase The guarantee covers proven material faults which will be corrected by us at no charge to you We wish to emphasise expressly that we reserve the right to replace the unit if a repair is impossible for economic reasons Proof of the commencement and progress of this guarantee period is the purchase receipt Repairs which our Service Department carries out for you do not extend the guarantee period Misuse and maltreatment such as reversed polarity excessive voltage and the effects of damp invalidate the guarantee The same applies to faults due to severe wear or excessive vibration The guarantee does not cover any additional claims such as consequent damage We expressly deny liability for damages which are caused by the device or arise through the use of the device Liability exclusion We are unable to ensure that you install and operate the battery backer correctly nor that the entire radio control system has been maintained properly For this reason we are unable to accept liability for loss damages or costs which result from the use of the backer or are connected with its use in any way Unless otherwise prescribed by2. 24 Professional developed by us and an extremely successful unit with remotely accessed channels i e remote gt from the receiver signal amplification voltage monitoring and much more besides it could be summed up as a complete servo receiver management system At that time all the top European pilots were still flying their models with four cell or five cell NC batteries or the then new NiMH packs but in the USA many leading flyers were already using Li lon batteries made by the renowned battery manufacturer DuraLite It was inevitable that Emory Donaldson Manager of Duralite would be present at the TOC and he showed great interest in the type of power supply represented by the PowerBox Professional There and then in Las Vegas he granted us a contract to develop a power supply system for DuraLite Li lon batteries which have a voltage curve similar to the LiPo types now in common use max 8 4 Volts Only five months later in April 2003 we were able to present him with a power supply system which contained a linear voltage regulator a completely new in house development two electronic switches double voltage monitor etc registered design DE 203 13 420 6 This linear voltage stabilisation circuit supplies a constant 5 9 Volts and offers a particularly high performance it has been employed unchanged in all our regulated battery backer systems and switches since 2003 All the companies which produce competing produc

4. the batteries you wish to use to the PowerBox The PowerBox 40 16 Evolution is equipped with five stabilised two way signal amplifiers i e a separate amplifier for each channel In our opinion this additional complexity is definitely worthwhile It completely eliminates the problem of crosstalk between the different channels which can occur when only one IC is used for this purpose The signal amplitude is maintained exactly at a constant 5 0 Volts another feature which is only found in our systems Many servos do not respond correctly to signals which fluctuate in voltage These modern short circuit protected signal amplifiers are also necessary in order to block out interference which could penetrate the system via the servo leads connected to the unit Naturally all our PowerBoxes are protected against reverse voltage which might be generated by servo motors PowerBox Systems POWER BOX Evolution 40 16 This measure is necessary because there are servos available on the market fitted with electronic circuitry which does not prevent reverse voltage Certain receiver types are also not protected against this potential problem The design of our PowerBoxes ensures that you can use any type of servo and receiving system In this case the ferrite rings fitted to the backer cables are not only designed to provide additional RF suppression since the integral servo signal amplifiers already fulfil this task reliably The ferrite rin

6. e modelling in general The PowerBox 40 16 Evolution is equipped with two independent IC controlled voltage monitors whose task is to check the performance of the two power sources Each monitor is assigned three coloured LEDs which indicate the actual voltage of the batteries i e one green one orange and one red LED indicate the voltage of each battery separately For this reason we recommend that you install the PowerBox 40 16 Evolution in your model in such a position that you can clearly see these voltage monitor LEDs PowerBox Systems POWER BOX Evolution 40 16 You should check before every flight by stirring the sticks that the voltage of both batteries remains stable If the batteries in your model are too weedy for the application i e of inadequate capacity this check will immediately show up the shortcoming In general terms small batteries of high capacity are not suitable for use as receiver power supplies because they have very high internal resistance this means that their current delivery capacity is often inadequate for powerful high speed digital servos Please believe what the voltage display tells you For even better monitoring of the power sources the battery backer also features a minimum value memory low voltage memory for both packs This memory records all voltage collapses separately for each battery during the flight This is a very important feature as it provides you with important inf
7. e reason for the possible discrepancy The PowerBox 40 16 Evolution is fitted with two independent IC controlled voltage regulators i e one regulator for each battery This duplication is known as redundancy However electronic components like any other technical parts are never 100 identical i e all components have a certain tolerance We do take the greatest trouble to select components for our products which exhibit the tightest tolerances according to the manufacturer s data sheets but we cannot completely avoid minor deviations Neither are all batteries 100 identical so it is not possible to eliminate the problem just by the selection process This means that a slight difference in the capacity of your batteries after several flights actually constitutes proof that your PowerBox contains two independent systems We are aware that other systems always feed absolutely identical capacities into the batteries We therefore ask you to consider for a moment whether this could really occur if as claimed the system contained two completely independent systems Our experience obliges us to conclude that these alternative systems actually contain no duplicated circuitry apart from the two batteries Both batteries are simply discharged via one regulator which provides power to the servos and the receiver In our opinion a process of this type does not represent a system with redundancy as required for valuable model aircraft and for saf
8. ent in a duplicated or redundant form This is precisely the approach taken by the PowerBox 40 16 Evolution The PowerBox 40 16 Evolution also provides you with remote access for up to five channels from the receiver We have coined this term because we are absolutely convinced and countless tests have confirmed our conviction that not all receiver channels should be operated using an external power supply Why should that be Well there is nothing fundamentally wrong with the standard receiver sockets and they are always adequate for certain servos and model functions Even so there are particular applications in model aircraft for which it is not good practice to use the standard receiver connections That is why we recommend that you set up remote access to certain channels from the receiver the channels concerned are these 1 Channels which are required to control multiple servos several servos per control surface hence integrated signal amplification required 2 Channels which are operated using very long servo leads more than 60 cm hence integrated servo signal amplification also RF suppression 3 Channels which have to supply extremely powerful high performance servos with correspondingly high current drain digital servos Jumbo servos Power servos in order to reduce the load on the receiver 4 Channels which require special interference suppression measures RF suppression of long servo leads turbine e
9. erating the unit safety notes It is essential to use low resistance batteries of the best possible quality to supply your receiving system Don t be tempted to use receiver packs of inadequate capacity as just one of them will have to power the whole system on its own if one pack should fail in flight We recommend that you use batteries of at least 1700 mAh capacity and for large scale models batteries of 3000 mAh or more are appropriate You can use either Nickel Cadmium NC batteries or Nickel Metal Hydride NiMH packs If you decide to use modern lightweight LiPo batteries we recommend the PowerBox Battery 1500 and PowerBox Battery 2800 from our own range wo ue TAR apa U kh 24 Battery 2s 3 S amp S S d 3 5 These LiPo batteries currently represent the safest most reliable battery packs available as they contain a balancer and a low voltage monitor as well as complete charge and security electronics 11 PowerBox Systems POWER BOX Evolution 40 16 Charging these batteries is as simple as charging a mobile phone Naturally each battery set includes a practical mount and accessories Of course it is possible to connect two separate receivers to this battery backer If you wish to do this be sure to observe the information supplied by your RC manufacturer concerning the use of two receivers in a model otherwise there may be problems with interaction between the two units minimum physical se
