OB-4 how to factory reset?

Hello everyone!

I am wondering if anyone knows how to factory reset the OB-4? ai can’t find any information on this on the internet about this or if it’s possible.

My issue is the scrub function is not working although the tape dial works for other functions like th metronome tempo change.

I have the latest firmware 1.5.8 and tried the motor calibration which causes the tape dial to move back and forth.

May help or issues much appreciated!

Cheers, Alan

factory reset won’t help you in that case, i’m afraid. please get in touch with support.

Hi jacobs, thanks for your advice. I tried the factory reset and calibration and you’re right it still does not work. I have contacted TE and hopefully i can take it in for repair maybe. Unfortunately it’s not under warranty. Cheers!

Can someone explain how to achieve a factory reset on the OB-4… I cannot find any documentation… It is probably super obvious but I cannot figure it out. Please help.

To factory reset, turn off the OB-4, then hold Input + Play and turn it back on.

Here’s the specifics on factory reset for OB-4:

:warning: IMPORTANT NOTE

Do not touch any of the dials or buttons while the unit calibrates itself as doing so can cause permanent damage to the device. make sure you understand this before starting this calibration.

got it? ok then, here’s how to do it:

  1. turn on your OB-4 and wait for it to start up in any mode.

  2. press and hold down [input] and [play] together for 18 seconds until the text ‘hold play to perform motor calibration’ is displayed on the led display.

  3. release both buttons and then press and hold [play] until ‘calibrating’ is shown on the display.

  4. OB-4 will start calibrating itself.

  5. :warning: IMPORTANT – DO NOT TOUCH ANY OF THE DIALS OR BUTTONS WHILE THE UNIT IS CALIBRATING AS DOING SO CAN CAUSE PERMANENT DAMAGE TO THE DEVICE.

  6. after the calibration process is complete you should find that operation is back to normal and that you have restored full control of the motors and functions.
