The louder the volume, the shorter the safe listening time is. Be sure to observe the following guide- lines when using your headset. • Listen at reasonable volumes for reasonable periods of time. • Be careful not to adjust the volume continuously upwards as your hearing adapts. • Do not turn up the volume so high that you can't hear what's around you. • You should use caution or tempo- rarily discontinue use in potentially hazardous situations. • Excessive sound pressure from earphones and headphones can cause hearing loss. • Using headphones with both ears covered while driving is not recom- mended and may be illegal in some areas while driving. • For your safety, avoid distractions from music or phone calls while in trac or other potentially dangerous environments. General information To avoid damage or malfunction: Caution  Do not expose headphones to excessive heat  Do not drop your headphones.  Headphones shall not be exposed to dripping or splashing.  Do not allow your headphones to be submerged in water.  Do not use any cleaning agents containing alcohol, ammonia, benzene, or abrasives.  If cleaning is required use a soft doth, if necessary dampened with a minimum amount of water or diluted mild soap, to clean the product.  The integrated battery shall not be exposed to excessive heat such as sunshine, re or the like.  Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type. About operating and storage temperatures and humidity • Store in a place where temperature is between -20°C (-4°F) and 50°C (122 °F) (up to 90% relative humidity. • Operate in a place where temperature is between 0°C (32°F) and 45°C (113 °F) (up to 90% relative humidity. • Battery life may be shorter in high or low temperature conditions. • Replacement of a battery with an incorrect tpye that can defeat a safeguard (for example, in the case of some lithium battery types); • Disposal of a battery into re or a hot oven, or mechanically crushing or cutting of a battery, that can result in an explosion; • Leaving a battery in an extremely high temperature surrounding environment that can result in an explosion or the leakage of ammable liquid or gas; • A battery subjected to extremely low air pressure that may result in an explosion or the leakage of ammable liquid or gas. 2 Your True wireless earphones What's in the box Philips True wireless earphones Philips TAT8505 Replaceable rubber ear caps x 3 pairs Quick start guide Other devices A mobile phone or device (e.g. note- book, PDA, Bluetooth adapters, MP3 players etc) which supports Bluetooth and is compatible to the headset (see 'Technical data' on page 8).

Note  Before you use your earpieces for the rst time, place the earpieces in the charging box and charge the battery for 3 hours for optimum battery capacity and lifetime.  Use only the original USB-C charging cable to avoid any damage.  Finish your call before charging the earpieces, as connecting the earpieces for charging will power the earpieces o. Connect one end of the USB cable into the charging box, and another end into the power source. • Charging process is veried by the blue LED light next to the USB socket on the case. • When the charging box is fully charged, the blue light goes on. • Charging process is veried by blue LED light on the earpieces. • When the earpieces is fully charged, the blue light goes o. • Place the earpiece to charging box. • Close the charging box cover. • Place the center of the charging case on the center of the wireless charger. • After fully charging, disconnect the charging case from the wireless charger. Tip Tip  The charging box serves as a portable backup battery for charging the earpieces. When the charging box is fully charged, it supports 3 times full recharge cycle for the earpieces.  Normally, a full charge takes 2 hours (for the earpieces or charging box) by USB cable. Tip  A full charge takes 4 hours b…

Test Procedure: Remove the antenna from the EUT and then connect a low loss RF cable from the antenna port to the spectrum analyzer. Use the following spectrum analyzer settings: a) Span: The frequency band of operation. Depending on the number of channels the device supports, it may be necessary to divide the frequency range of operation across multiple spans, to allow the individual channels to be clearly seen. b) RBW < 30% of the channel spacing or the 20 dB bandwidth, whichever is smaller. c) VBW ≥ RBW. d) Sweep: Auto. e) Detector function: Peak. f) Trace: Max hold. g) Allow the trace to stabilize. Note: The cable loss and attenuator loss were offset into measure device as an amplitude offset. Test Setup: Refer to section 4.5.3 for details.

The average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of 0.4 seconds multiplied by the number of hopping channels employed. Test Procedure: Remove the antenna from the EUT and then connect a low loss RF cable from the antenna port to the spectrum analyzer. Use the following spectrum analyzer settings: a) Span = zero span, centered on a hopping channel b) RBW shall be ≤ channel spacing and where possible RBW should be set >> 1 / T, where T is the expected dwell time per channel. c) Sweep = As necessary to capture the entire dwell time per hopping channel; where possible use a video trigger and trigger delay so that the transmitted signal starts a little to the right of the start of the plot. The trigger level might need slight adjustment to prevent triggering when the system hops on an adjacent channel; a second plot might be needed with a longer sweep time to show two successive hops on a channel. d) Detector function = peak e) Trace = max hold f) Use the marker-delta function to determine the dwell time Note: The cable loss and attenuator loss were offset into measure device as an amplitude offset.
