The bluetooth light is always on, now you can play music on your device by bluetooth. 2.When the bluetooth is connected successfully and you make calls with phone, the voice will automatically enter into the bluetooth hands-free mode.Short press “ ”key to answer incoming call,Long press to reject call. Please connect 3.5mm audio cable to the headphone of the phone/computer output interface, short press “ ” key switch to AUX in mode.When you hear a prompt tone“AUX in mode”, then you can play music. Due to the lower power supply capability,most computer’s USB interface can not meet speaker’s operational requirements.It is not recommended to use the computer’s USB for charging synchronously when you play music in the AUX in mode while connecting computer. If they connected succesffully ,music will play on the speaker shows dual stereo sound effect. Note:This function requires two M8 speakers,make sure both are turned on and in the bluetooth mode. No bluetooth connection to any other devices before TWS paring. When TWS is connected, short press“ ”key of one speaker to cancel the Do not use power adapter that has not been certificated by safety certification. Power adapter with output 5V-2A is recommended for charging. 1.When you hear a prompt tone “Out of battery”,Please charge speaker as quickly as possible. 2.This speaker supports self-adaption charging . It’s able to choose charging current automatically according to the external rated power of the adapter, When charging by USB interface on computer, the current is smaller and it takes longer time to complete charging. 3.When speaker is charging, the power light is red and always on. When speaker is fully charged,the power light is green and always on. Kindly tips: This product is waterproof on daily basis conditions,and it can washes normally. Do not soak the product in water for a long time(If the prodcut malfunction due to water ingress, our company reserves the right of final Explanation). Energy saving: The speaker will automatically shut down to save power under below circumstances. 1.In bluetooth mode,after 20 minutes waiting for no device pairing. 2.In any modes, short press “ ”key pause for 20 minutes without any operation the speaker will shut down automatically, Please long press the power key to turn it on again. ※The function of power bank is forbidden when the speaker is charging. Both states can not exist at the same time. 1.USB-A OUTPUT : 5V/1A(Power bank function only works when speaker is turned on. 2.Turn on speaker insert the standard USB cable into the output interface of power bank, connect the other end to the mobile. At this time the power bank indicator is green, the green indicator will be off after mobile being fully charged. 3.Turn off speaker in the process of using speaker to charge the mobile,speaker will stand by,power bank function works normally, and speaker can be awakened by long press the power key. ※The USB and Type C interfaces of the same charing line are forbidden to be inserted into the speaker simultaneously. 1.Can not connect to bluetooth or no sound when playing music? Please make sure the speaker is in bluetooth mode,and also make sure your device supports bluetooth function and bluetooth has already been turned on searching for devices. Check if there are too many bluetooth devices around ,which might bring difficulties of the searching process. Please turn off other bluetooth device. 2.What if TF card doesn’t respond ? Please make sure TF card is in good quality,and check whether the audio file is MP3 playing format,If all problems above are exc…

Shenzhen BCTC Testing Co., Ltd. FCC ID:2AVFK-M8 RF EXPOSURE EVALUATION 1. Introduction According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency(RF) Radiation as specified in §1.1307(b), a device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 cm is normally maintained between the transmitting antenna and the body of the user or nearby persons. In this context, the term “fixed location” means that the device is physically secured at one location and is not able to be easily moved to another location. Transmitting devices designed to be used by consumers or workers that can be easily re-located, such as wireless devices associated with a personal computer, are considered to be mobile devices if they meet the 20 cm separation requirement. The limits to be used for MPE evaluation are specified in §1.1310. All unlicensed personal communications service (PCS) devices and unlicensed NII devices shall be subject to the limits for general population/uncontrolled exposure. 2.RF Radiation Exposure Limits According to 47 CFR §1.1310, the criteria listed in below table shall be used to evaluate the environmental impact of human exposure to RF radiation as specified in §1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of §2.1093. Notes: 1. f = frequency in MHz 2. Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. Limits for occupational/controlled exposure also apply in situations when an individual is transient through a location where occupational/controlled limits apply provided they are made aware of the potential for exposure. 3. General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or cannot exercise control over their exposure. Shenzhen BCTC Testing Co., Ltd. 3.MPE Assessment Method Calculations can be made to predict RF field strength and power density levels around typical RF sources. For example, in the case of a single radiating antenna, a prediction for power density in the far-field of the antenna can be made by use of the general Equations below. This equation is generally accurate in the far-field of an antenna but will over-predict power density in the near field, where they could be used for making a "worst case" or conservative prediction. Where S = Power Density, unit in mW/cm2 P = Power input to the antenna, unit in mW G = Power gain of the antenna in the direction of interest relative to an isotropic radiator R = Distance to the center of radiation of the antenna, unit in cm EIRP = Effective isotropically radiated power 4. MPE Calculation for Standalone Operations Operation Frequency: 2402-2480MHz Power density limited: 1mW/ cm 2 Antenna Type: Internal antenna Antenna gain: 2dBi R=20cm mW=10^(dBm/10) =3.1416 Modulation Channel Freq. (MHz) Conduct ed power (dBm) Tune-up power (dBm) Max tune-up power (dBm) Max tune-up power (mW) Antenna Gain Numeric Evaluation result (mW/cm2 ) Power density Limits (mW/cm2) 2402 1.682±13.00 2.001.590.000631 24412.072±13.00 2.001.590.000631 24802.20 2±13.002.001.590.000631 24022.43 2±13.002.001.590.000631 24412.793±1 4.002.511.59 0.000791 2480 2.933±14.002.51 1.590.000791 GFSK Pi/4DQPSK Conclusion: For the max result : 0.00079≤ 1.0, compliance with FCC's RF Exposure. Summary: Since the ERP (effective radiated power) operated at < 1.5 GHz is less than 1.5 watts and > 1.5 GHz is less than 3 watts, the routine environmental evaluation is not required, and the MPE result calculated for this device complies with the MPE limit as specified in 47 CFR §1.1310.
