To prevent possible hearing damage, do not listen at high volume levels for long periods. OSHA GUIDELINES FOR NOISE EXPOSURE LIMITS The Occupational Safety Health Administration (OSHA) has issued headphone usage recommendations for maximum daily exposure and sound pressure levels [measured in decibels (dB)]. A decibel is a unit of sound measurement that increases exponentially with volume. For example, conversational speech is typically around 60dB, and a rock concert in a stadium is often about 110dB. 90dB8 hours 95dB4 hours 100dB2 hours 105dB1 Hour 110dB30 minutes 115dB15 minutes 120dBAvoid as damage may occur FCC WARNING This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction FCC ID: SVC-M4UTWM Because the True Wireless Micro Planar Earphones(PSB M4U TWM) is too small, the label information has been included in the user manual and outer packaging box, as shown in the manual. FCC lable: SIZE:40*20mm WARNING Warnings or announcements may be unnoticed when you are using the earphones. Please be aware of ambient sounds while wearing the earphones and recognize them as needed. •To prevent possible hearing damage, do not listen at high volume levels for long periods. •These earphones should only be connected to a USB interface of version USB2.0 or higher. •Risk of explosion if the battery is replaced by an incorrect type, dispose of used batteries according to the instructions. •Be sure to read the Owner’s Manual of the device that you want to connect to these earphones. •Check the volume settings when using the earphones when in public places and ensure that you do not disturb people around you. •These earphones are not guaranteed to work with all combinations of Bluetooth devices/ mobile phones. •These earphones do not support a connection with all Bluetooth devices/mobile phones. •Bluetooth wireless technology can communicate up to approximately 10 m. Obstructions (people, metallic objects, walls, etc.) and radio wave conditions affect the actual range. •The Bluetooth device that you want to connect with must support the same profile as these earphones in order to use the Bluetooth function. For details on profiles that the Bluetooth device is compatible with, see the Bluetooth device Owner’s Manual. •Due to features of Bluetooth wireless technology, playback of audio on the earphones is slightly delayed compared to the playback on the transmitting device. •Do not use your earphones while driving. •Remove the earphones immediately if you experience a warming sensation or loss of audio. •Do not use mobile phone adaptors to connect these earphones to airplane seat jacks, as this could cause overheating and result in injury or property damage. •The earphones and accessories contain small parts which may be a choking hazard.

According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g SAR and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)]·[√f(GHZ)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where: • f(GHZ) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
