If a mobile phone is tested with a separation distance of 15mm or 25mm, does the user manual have to include the SAR related distance, like the FCC?

For R&TTE directive compliance we would be looking for the user information to provide RF Exposure guidance when there is a separation distance used for SAR testing of portable devices or the compliance boundary which is applicable which was applicable for any RF Exposure MPE calculations, primarily to inform the user as to how the manufacturer advises the device to be operated as well as the operational instructions to meet the R&TTE RF Exposure guidelines. If a mobile handset is tested with a 15mm or 25mm separation for near body usage, the user manual should state that a separation i.e. of 15mm or 25mm should be maintained between the device and the body during transmission or operation. It is also recommended, that for portable devices the user manual also provide guidance on approved holsters and any accessories which were subject to test.

There is guidance in the EN 62209-2 standard which specifies that for evaluation of body SAR without a specific accessory, the separation distance used for SAR test cannot be more than 25mm.
