protected.  The  maximum  current  on  the  input  connector  is  10  A,  so  take  care  of  that  the 
maximum power of all the attached peripherial devices is under 100 W! Always make sure, 
that you are using a 12 V power supply that has the necessary output power rating to power 
all of your connected devices!  
 
Now you can turn on the controller with the main switch. The platform moves to the home 
postion 

– it may take 1-2 minutes-, then the tracking starts automatically after a warning 

beep. 
 

ATTENTION! Right after you turn on the controller, you will hear a beep, then the 

platform initializes, which means that axles start to move! Keep away your fingers off 

the platform to avoid any injuries! 

 
 
 

2.5.4 Wireless Remote Controller 

During the active tracking you can use the remote controller to control it’s movement or to 
search an object in the sky.  
 

ATTENTION! Remote controller has a built in, rechargeable lithium polymer battery! 

Battery is not replaceable at home! Do not disassemble it! Do not expose it to direct 

heat or sunlight! Do not leave it in a car that can warm up on sunlight! Never leave it 

unattended during charging! Do not use and do not attempt to charge it if the house is 

broken! Do not use in rain, the remote controller is not waterproof!  

 
The functions of each button is shown below:

 

 

The remote controller has a key lock function to prevent unwanted movements. To unlock the 
remote  controller,  press  and  hold  the  ENABLE 

button.  Once  it’s  enabled,  the  built-in  LED 

indicator shows the state of the charge of the battery: 

-

 

green:

 

battery level is OK, it’s over 30% 

-

 

red:

 

bettery level is low, it’s under 30% 

-

 

flashing red:

 

battery is too low, connect it to a charger 

If  the  red  light  is  flashing,  the  remote  controller  doesn’s  send  any  signal  to  the  platform 
controller,  so  connect  it  to  a  charger  as  soon  as  possible.  Remote  controller  can  be  used 
during charging.  
 

To charge the remote controller

 you can use any standard 5V USB power source or phone 

chargers with microUSB cable, or you can use the rear USB connector of the TEPP connector. 
During  charging  the  built  in,  blue  LED  lights.  Charging  time  is  around  6-8  hours.  Once  the 
charging has ended, the blue light turns off. 
 
To  control  the  TEPP,  push  or  pull  the  joystick  to  the  desired  direction,  while  the  ENABLE 
button is pressed. If the platform controller receives the signals it will sound very short beeps. 
If you don’t hear this continous clicking sound, you’re probably out of the range, so go closer
