MASTER Series
1. Safety and operating instructions
Building and operating remotely controlled models requires a high level of technical com-
petence, careful handling and a particular emphasis on safety. Inaccurate and faulty
construction as well as inattentive and careless operation can result in significant prop-
erty and/or personal injuries. Consequently, particular emphasis should be placed on
working carefully and on the prudent operation of our controllers.
The CE mark guarantees the conformance with the applicable laws ensuring trouble free
operation; it does not however entitle you to careless handling of the controller. The
MASTER product series was developed exclusively for use in radio controlled models.
The controller may not be under any circumstances be used in man-carrying aircraft,
man-carrying vehicles or the like.
The MASTER Prog-Box is designed for use with batteries only. Do not use the Prog-Box
with a power supply, incorrect voltages can destroy it. Never connect the Prog-Box to
alternating current (typically 100-230 V).
Remove the propeller or other rotating objects prior to programming the controller. Be
sure to remove other objects that may be able to come into contact with the rotating parts
of the motor assembly. Mechanical or electrical defects may lead to sudden, unexpected
starting of the motor. Please be sure to protect yourself from the danger that may result
in particular from rotating propellers or rotor blades.
The Prog-Box should be protected against the effects of vibration, dust, moisture, shock
or pressure. Inspect the Prog-Box for damage at regular intervals. Should the device
have been exposed to moisture it should not be used again until it has been thoroughly
dried and closely inspected? The Prog-Box should not be used if it has been damaged
and must be sent to our service department for repair should you wish to use it in the
future.
No modifications or alternations of any type may be made to the Prog-Box.
Use the device only in ambient temperatures between –10
o
C/+14
o
F and +50
o
C/+122
o
F.
The Prog-Box may only be used in an environment free of static electricity.
The Prog-Box is not protected against reversed polarity, reversing the connecting leads
will cause it to be damaged or destroyed.
Should a BEC be used as the power source for the Prog-Box, a receiver battery may not
be connected in parallel. Doing so will inevitably result in the destruction of the BEC cir-
cuitry. If it is desirable to use a controller with BEC in conjunction with receiver battery,
then the red (+) connecting lead must be removed from the receiver connector of the
MASTER controller. When using the UNI connectors employed by the MASTER series, a
small screwdriver may be used to loosen the retaining mechanism and to then to push
the lead out of the connector. The loose end must be carefully insulated. Once the BEC
is inoperative a receiver battery may be connected without danger.
Connect the throttle servo cable of the controller to the corresponding connection on the
Prog-Box.
The MASTER Controllers are pre-set for optimal use with Hackler Brushless Motors on
delivery. The motor brake is activated for fixed wing models. Please refer to this user
guide for the appropriate settings for other motors.
