The dialer code *#07# on an iPhone is a specific shortcut used to access detailed information about your device's RF Exposure (Radiofrequency Exposure) and Specific Absorption Rate (SAR) values. This code provides direct access to regulatory information concerning the maximum amount of RF energy absorbed by the body from the phone.
Understanding the *#07# Code
When you dial *#07# and press the call button on your iPhone, it doesn't initiate a phone call. Instead, it triggers a hidden diagnostic screen that displays important compliance and exposure data. This is particularly useful for users interested in understanding the RF emissions of their device, a standard regulatory requirement for all mobile phones.
Here's a quick overview:
| Dial Code | Information Accessed | Purpose |
|---|---|---|
*#07# |
RF Exposure, SAR Value(s) | To view your iPhone's Specific Absorption Rate (SAR) values. |
How to Access Your iPhone's SAR Value with *#07
Accessing your iPhone's SAR information using the *#07# code is a straightforward process:
- Open the Phone app on your iPhone.
- *Dial `#07#`** into the keypad.
- Tap the Call button. Instead of making a call, a new screen titled "RF Exposure" will appear.
- On the "RF Exposure" screen, select the option related to RF Exposure if multiple options are presented, or directly look for the SAR value link at the bottom of the page.
- Tap on the SAR value link. This will navigate you to a new page containing detailed information about your iPhone's SAR values for different usage scenarios (e.g., head, body).
- Scroll down on the new page to view the specific SAR values for your iPhone model.
Understanding Specific Absorption Rate (SAR)
Specific Absorption Rate (SAR) is a measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) electromagnetic field. It is the internationally recognized measure for checking whether mobile phones are within safety guidelines.
- Measurement: SAR values are typically expressed in watts per kilogram (W/kg).
- Regulatory Limits: Regulatory bodies worldwide, such as the Federal Communications Commission (FCC) in the United States and the European Union, set limits for SAR to ensure the safety of mobile devices. For instance, the FCC limit for mobile phones is 1.6 watts per kilogram (1.6 W/kg) averaged over one gram of tissue.
- Purpose: The information displayed via the *#07# code confirms that your iPhone complies with these international RF exposure guidelines. For more detailed information about Apple's commitment to RF exposure and SAR values, you can refer to official sources like Apple's RF Exposure information.
