1 INSTRUCTIONS 3 Welcome Warning What you need to understand before using foc.us What’s in the box Before starting Getting started Calibrate your foc.us Programs Starting & Stopping a Session Welcome The foc.us v2 is an advanced micro current signal generator. Download the latest version of this manual from: http://www.foc.us/v2/downloads foc.us is designed to be used by healthy adults who do not suffer from epilepsy, brain or mental health conditions or have a metalic implant such as a skull plate, cochlear implant, pace-maker or others. Setup options foc.us dock & software Intended use Bluetooth® connection Troubleshooting Specifications Support Glossary FCC Warranty & Guarantee Contents 3 4 6 9 11 13 15 17 19 20 23 24 24 25 26 26 27 28 29 5 Warning If you suffer from epilepsy, seisures, brain lessions, bipolar depression or severe heart disease you should not use the foc.us headset. If you experience short term negative effects with foc.us you should immediately stop using it. This is not a toy and is not intended to be used by anyone under the age of 18 years old. If using your own electrodes it is not recommended to create novel electrode placements. Do not position the electrodes so that the current may pass through the brainstem. Do not position the electrodes over cuts, grazes or damaged skin. Allow at least 48 hours between usage. Always use the electrodes with wet sponges. Do not touch the metal electrodes as this can lead to burns. 7 What you need to understand before using foc.us foc.us is designed to improve your mental gaming skills. You are exciting and inhibiting sections of your pre-frontal cortex with an electric current. Possible side effects include tingling sensations under the electrodes or on the scalp, visual artifacts, nausea, headaches and fatigue. If you experience any of these you should stop using foc.us. Repeated use may lead to skin irritation. If you exceed the recommended durations you increase the risk of consolidating both the excitatory and inhibitory processes. You may feel a tingling sensation, or a hot or cold sensation. If this is uncomfortable or painful then you should stop session and remove the electrodes. Redness may appear under electrodes after use which will disappear after a short time. Foc.us should not be used during any activities other than seditary gaming. If you see white flashes, or phosphenes you should adjust the position of the headset on your head, pushing it further back away from your eyes. 9 What’s in the box 1. foc.us v2 2. foc.us dock 3. micro-usb cable for recharging 4. this instruction booklet 1. 2. 3. 11 Before starting Firmly push the v2 into the provided dock and connect the dock to a USB power supply to recharge.

Airplane mode - turns off bluetooth PIN - the default PIN is 000000 Reset - reset your foc.us device to factory settings Security - please set your foc.us device to lock to prevent un-authorised usage. Language - if your language is not supported please contact [email protected] Session - foc.us+ session sharing settings Warnings - it is not recommend to use your foc.us more than once every 48 hours. 23 foc.us dock & software The foc.us dock and software can be used to update the firmware of your v2. It can also be used to sync your program and session data with foc.us+ 25 Intended use Use foc.us in accordance with the guidelines of the connected headset WARNING: If you attach external electrodes, make sure you know what you are doing. You have a responsibility to ensure they are not placed in positions that could be dangerous including but not limited to passing current through the brain stem. Bluetooth® connection foc.us can be controlled by bluetooth.

TRaC Global Test Report: TRA-023656-01-47-01A 54 Appendix G: SAR Exclusion & MPE Calculation KDB 447498 Section 4.3 General SAR test reduction and exclusion guidance For Standalone SAR exclusion consideration, when SAR exclusion Threshold requirement in KDB 447498 is satisfied, standalone SAR evaluation for general population exposure conditions by measurement or numerical simulation is not required. In the frequency range 100 MHz to 6 GHz and test separation distance of ≤ 50mm, the SAR Test Exclusion Threshold will be determined as follows SAR Exclusion Threshold (SARET) SAR Exclusion Threshold = Step 1 + Step 2 Step 1 NT = [ (MP/TSD A ) * √ f GHz ] NT = Numeric Threshold (3.0 for 1-g SAR and 7.5 for 10-g SAR) MP = Max Power of channel (mW) (inc tune up) TSD A = Min Test separation Distance or 50mm (whichever is lower) = 5mm (in this case) We can transpose this formula to allow us to find the maximum power of a channel allowed and compare this to the measured maximum power. = [(NT x TSD A ) / √ f GHz ] For Distances Greater than 50 mm Step 2 applies Step 2 (TSD B – 50mm) * 10} Where: TSD B = Min Test separation Distance (mm) = 50 Note: Step 2 is not required here as the TSD A is less than 50mm. TRaC Global Test Report: TRA-023656-01-47-01A 55 Operating Frequency 2.402 GHz SARET = [(3.0 x 5) / √2.402] SARET = 9.68mW Operating Frequency 2.440 GHz SARET = [(3.0 x 5) / √2.440] SARET = 9.60mW Operating Frequency 2.480 GHz SARET = [(3.0 x 5) / √2.480] SARET = 9.53mW Channel Frequency (MHz) EIRP (mW) SAR Exclusion Threshold SAR Evaluation 2402 2.26 9.68 Not Required 2440 1.77 9.60 Not Required 2480 1.35 9.53 Not Required Therefore standalone SAR evaluation for general population exposure conditions by measurement or numerical simulation is not required.
