    There’s a power button on the transmitter but not the receiver. It simply goes to sleep and displays the time/clock.

  • Sissy

    Which model for Nikon D7100 SLR?

  • ede

    I cannot comprehend what is so difficult about including a manual slide switch to power off both units. You did it on the receiver, why not on the transmitter. There is nothing more anoying than coming to the site to find out that one cannot make the photos you intend to shoot because of two small – flat – batteries.

  • Aputure

    Great, u offered us a very nice proposal. Also plz feel free to use it, it supports long battery life. U can check it here. Better to use rechargeable batteries.

  • andrian

    can it do half press?

  • Aputure

    Yes, half press the shutter release button to autofocus and full press it to fire the shutter.

  • Aputure

    Thanks for your email ,glad to answer your following questions as below : .

    Q 1 : I don’t understand the difference betweend “LONG” and “INTVL”: the intervalometer seems to wait LONG + INTVL seconds before exposure

    A1:”LONG”means long exposure,”INTVL”means interval .
    Yes ,it will begin to work after “LONG + INTVL” :)

    Q2:on the screen it is displayed “INTUL” instead of INTVL

    A2: Thanks for telling us ,could you tell us the model number in your hand ?We will check and revise then :).

    Q3: The red/green light don’t work in the remote mode
    A3: That means the signal sources of transmitter and receiver are not the same ,please check and try again :).
    Any questions please let us know

    The length of antenna affect your controling for your camera. The perfect length of antenna is 17.25cm. Please keep your antenna in 3/4 long and remote it.
    PS if you have any questions, you would send email

    Best regards

  • Aputure

    Please try it again as follows:
    Put the batteries in transmitter, receiver and camera, and then switch transmitter and camera on at first.
    Plug the receiver in camera.
    Set the transmitter in channel 1 and keep it in Remote Mode.
    Switch the receiver on and keep pressing the set button till the indicator lasting red.
    Set all time details in transmitter and keep it in Timer Mode when you want to time remote your camera.
    Press Start/Stop button. You can control it.
    And I have to emphasiz the following things:
    do not switch the receiver on so early before you connect it with transmitter. It will sleep within 10 seconds if without operation.
    make sure you have switched your camera on when you connect transmitter with receiver.
    Keep the screen of transmitter in Remote Mode when connect
    transmitter with receiver. And also keep it in Timer Mode when you’d like to time remote your camera.

    Can this product be used to control shooting in video mode on a Canon 1100 EOS?

  • Aputure

    Hi,The Pro Coworker is a product used for shooting,not recording. If you need to use it in video mode,please check Aputure V-Remote IR controller which makes video shooting easier than ever.

    Hi Bert,Many thanks for contacting again!
    I am sorry,Aputure only warrants the original consumer from defects for 1 year.According to your description,I think you can replace the battery connection if you know soldering.And I need to suggest you remove the batteries when you do not use the product:-)
