Congratulations on your decision to purchase the Graupner/SJ PRX stabilised receiver power
supply. The PRX is intended exclusively for use in battery-operated radio-controlled models; we
do not condone its use for any other type of application. It is absolutely prohibited to use the unit
in any vehicle designed to carry people.
If you wish to use the unit successfully it is important to understand its features and operate it
correctly.
Please read these operating instructions carefully before using the unit for the first time.
Warning notes
- The fact that this device has been granted a CE certificate does not relieve you of the obliga-
tion to use it with due care and attention.
- It is important only to use Graupner/SJ or GM-Racing batteries which are suitable for use with
the PRX. Ensure that the battery or batteries contain the correct number of cells, and that the
output voltage is as stated in the Specification.
- Batteries should always be disconnected from the PRX for charging. We also recommend that
you remove them from the model.
- Never leave your RC model unsupervised when a battery is connected. If a fault should occur,
this could cause a fire in the model or to other objects in the vicinity.
- Never allow the PRX or other electronic components to come into contact with water. Protect
the PRX from dust, dirt, damp, vibration, extreme cold and heat and foreign bodies.
- All cables and connections must be well insulated, as short-circuits could wreck the PRX.
Always take great care to avoid reversed polarity.
- The PRX is not a plaything, and is not suitable for young persons under fourteen years of
age.
- The PRX is intended exclusively for use in battery-operated radio-controlled models; we do
not condone its use for any other type of application. It is absolutely prohibited to use the unit
in any vehicle designed to carry people.
- Motors, gearboxes, boat propellers and aircraft propellers are potentially dangerous objects.
For this reason keep well away from the hazard zone around and in front of the power sy-
stem.
- Always check the aircraft's working systems before flying the model, and carry out a range
check on the ground (hold your model securely) before you fly it. Repeat the check with the
motor running, opening the throttle occasionally to check its effect on the RC system.
- It is not permissible to carry out modifications of any kind to the PRX.
- Liability exclusion: As manufacturers, we at Graupner/SJ are not in a position to influence
the way you install, operate and maintain the PRX. For this reason we are obliged to deny all
liability for loss, damage or costs which are incurred due to the incompetent or incorrect use
and operation of our products, or which are connected with such operation in any way.
Use only the components and accessories which we recommend, and be sure to use genuine
and compatible GRAUPNER/SJ connectors and accessories.
