Signalis Guide | How To Solve Office Wall Safe Puzzle

In SIGNALIS, solving the office wall-safe puzzle is critical to advancing through the game. This article will walk you through the steps in full, including the frequencies required to open the safe and retrieve the important identity card within.

Finding The Frequencies Document

The first step in unlocking the office wall safe is to find the frequency paper. This document, Memorandum: Wall Safe Codes, may be found in the Office area. It gives you a critical hint by revealing that at least one employee is aware of the broadcasting frequencies associated with the wall safe.

You'll need to find this paper because it provides the frequencies required to complete the challenge. If you're stuck, make sure you've extensively investigated the area since the paperwork should be available by the time you attempt to answer this challenge.

Searching The Interrogation And Isolation Rooms

Once you have the frequency sheet, the next step is to determine the particular radio frequency required to open the office wall safely. Proceed to the Interrogation and Isolation Rooms, which are just to the left of the Office area. Searching these rooms will supply you with the necessary information to progress.

Using The Radio To Tune Into The Frequency

After gathering the relevant information, go to your inventory and locate the frequencies specified there. You should discover one for frequency IC3, which is set to 173. Entering this frequency into your radio will produce a five-digit code. In my situation, the code produced was 43947.

The technique may differ slightly depending on your gameplay, but the premise is the same: tune your radio to the correct station and record the code.

Inputting The Code Into The Office Wall Safe

With the five-digit code in hand, proceed to the office wall safe. The safe should have a tree symbol on it, which is where you will enter the code. To unlock the safe, enter the code (in this case, 43947) and hit the button.

Don't forget to twist the dial after inputting the code; the safe's mechanism requires it. This is a minor but critical step that ensures the safe unlocks properly.

Obtaining The Identification Card

After unlocking the safe, open it to find the identification card inside. You must obtain this card to continue your journey through SIGNALIS, so make sure to do so before proceeding.
