    STEP 2: Keep everything aligned and attach the bottom part to the top part.

    STEP 3: Rotate the ring clockwise until hearing a snap, the button should be automatically popped out and aligned with a locked icon.

     
     
    Disconnect

    STEP 1: Press and hold the button.

    STEP 2: Rotate the ring counterclockwise.

    STEP 3: When the button aligns the unlock icon, the T7 can be detached from the top part of Hyper Quick Release.

     
     
     
  • 08. Powering Up The GREMSY T7

    After connecting to the power supply, the gimbal will perform a series of alignments, self tests, which last about 2 seconds and will determine the status of the gimbal, indicated by the Status LED color. During this time, don’t touch the gimbal or camera.

    Always start the gimbal with a balanced camera set up otherwise after initialization the controller will return an error followed by a red color indicator.

     
    Step 1

    Make sure the Hyper Quick Release is mounted to the drone and its power port is already connected to the power supply correctly. Next, let’s mount the gimbal to the Hyper Quick Release, it will be automatically powered up.

     
    Step 2
    Wait about 2 seconds, do not touch the gimbal or camera.
     
    Step 3
    If the status LED is blinking green, the gimbal is ready for use. By default, the gimbal is in Follow mode if the motors are turned ON by the Function Button.
     
    If the status LED is solid red, something is wrong with the gimbal and motors can not start. Connect to the software/apps to check details of the error message.
     
    Read “LED STATUS INDICATOR” in next section for more information.

  • 10. Operation Modes
    GREMSY T7 HAS 2 OPERATION MODES

    LOCK MODE: is a stabilization mode where the camera maintains orientation independently of the rest of the gimbal and the orientation can be changed by an external control signal from remote control.

    FOLLOW MODE: in this mode, the camera will mimic the operator’s movement and allows one person to control camera tilt and pan without using an external device like a remote control.

     
     
    GREMSY T7 Supports

    SINGLE OPERATOR: using FOLLOW mode.

    DUAL OPERATOR: a second operator can use a Remote Controller (SBUS, SPEKTRUM, PPM) to control gimbal’s movement.

     
     
  • 11. Working Operation

    GREMSY T7 has 2 working operations: Normal and Inverted.

     
    After powering up the gimbal , it will automatically detect if the gimbal is in inverted operation or normal operation based on pan motor position.
    During working, switching to another working operation made easy by changing pan motor position, the gimbal will automatically detect new types of working operation.

    Swithing Between Modes

    Using function button

    PRESS TIMES MODES
    Once time Turn motors ON
    2 times Lock mode
    3 times Follow mode
    Hold 3 seconds Turn motor OFF
     
     

    Using mode channel on remote control

    POSITIONS MODES
    High Follow mode
    Motors ON
    Midle Lock mode
    Motors ON
    Low Motors OFF
     
     
     

    Using software/application

    If there is a remote control signal, changing modes or turning motors on/ off by other methods such as using the function button or software will not take effect because the remote control signal has the highest priority and override the command.

    USING BLUETOOTH CONNECTION
    ON MOBILE APP
    STEPS TO CONNECT:
    • 1 - Enable bluetooth adapter of mobile devices
      On Android: the OS will ask for Location Data permission for BLE scanning feature (updated by Google since Android 6.0)
      On iOS: the OS will sometimes have issues with its Bluetooth adapter. Users should check the device’s quick settings and general settings to enable the adapter and the Bluetooth icon should appear on the device’s status bar.
    • 2 - Turn ON the gimbal and run the app.
      After switching to Bluetooth, the app will begin scanning for Gremsy Bluetooth integrated gimbals.
      If only one gimbal is found, it will be connected automatically.
      If more than one gimbal is found, a list of gimbals will be shown to allow the user to select the desired one.
      If no gimbal is found, an error will be shown.
