While exploring Arkham Asylum in Mission 7.2 – Talia Al Ghul, you’ll eventually grapple into a tower filled with sonic equipment. You need to solve a puzzle here to proceed — in this guide, we’ll show you how to align the frequencies, solving the puzzle.
Reset sonic device
Upon entering the tower, your first step will be to reset the sonic device so you can begin the puzzle. Simple approach the console on the far wall, and a prompt will appear. When it does, hold / / to reset the sonic device.
Align the frequencies
Now you’ll need to set each oscilloscope (the 4 machines that sit on the left and right walls) to the correct frequency. This must be done in a specific order, indicated by the order in which the oscilloscope frequencies appear on the console’s screen. You can also see the correct order in which to interact with the equipment by looking at the image below. After resetting the sonic device (labeled 1), set the frequency on the oscilloscope labeled 2, then 3, and so on.
By walking up to each oscilloscope, you’ll be able to hold / / to change the frequency. If the frequency display remains red, you’ll need to hold the button again — repeat until the frequency displayed is green. If you make a mistake, you can reset the puzzle by interact with the main console to reset the sonic device again (labeled “1” in the image below).
Once you’ve got all four frequencies correct, the console’s screen should display a series of green frequencies, and you’ll be able to continue with the mission!
We hope this guide on how to the oscilloscope puzzle was helpful! As always, questions and suggestions are welcome in the comments below.
