To avoid burns, DO NOT let bare skin touch hot surfaces. If provided, use handles when moving this heater. Keep combustible materials, such as furniture, pillows, bedding, papers, clothes, and curtains at least 1 meter (39 inches) from the front of the heater and keep them away from the sides and rear. • Extreme caution is necessary when any heater is used by or near children or invalids and whenever the heater is left operating and unattended. • DO NOT operate any heater with a damaged cord or plug or after the heater malfunctions, has been dropped or damaged in any manner. Disconnect power at service panel and have heater inspected by a reputable electrician before reusing. • INDOOR use only! NEVER use this heater outdoors! Doing so may result in electric shock! • To disconnect heater, turn controls to off, and turn off power to heater circuit at main disconnect panel. • DO NOT run power cord under carpeting. DO NOT cover power cord with throw rugs, runners, or similar coverings. DO NOT route power cord under furniture or appliances. Arrange power cord away from traffic area, and where it will not be tripped over. • DO NOT insert or allow foreign objects to enter any ventilation or exhaust opening, as this may cause electric shock or fire, or damage the heater. • To prevent a possible fire, DO NOT block air intakes or exhaust in any manner. • A heater has hot and arcing or sparking parts inside. DO NOT use it in areas where gasoline, paint, or flammable liquids are used or stored. • Use this heater only as described in this manual. Any other use not recommended by the manufacturer may cause fire, electric shock, or injury to persons. 3 • This appliance MUST be grounded. • ALWAYS plug heaters directly into a wall outlet/receptacle. NEVER use with an extension cord or relocatable power tap (outlet/power strip). • NEVER use this heater in bathrooms, laundry rooms, or any other location where the heater could fall into a bathtub or pool, become damp, or come in contact with water. • AVOID FIRE! Regularly inspect all air vents to make sure they are free from dust, lint, or other blockage. Unplug the unit and clean with a vacuum ONLY. DO NOT rinse or get wet. • NEVER hang this unit on a wall directly below an electrical outlet. • WARNING: DO NOT DEPEND ON THE ON/OFF SWITCH THE SOLE MEANS OF DISCONNECTING POWER WHEN SERVICING OR MOVING THE HEATER. ALWAYS UNPLUG THE POWER CORD. • WARNING: REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK— DO NOT USE THIS HEATER WITH ANY SOLID STATE SPEED CONTROL DEVICES. • For residential use only! NOT for commercial use! Any commercial or public use of this heater voids all warranties, and could cause injury. • This product is not intended to be a primary heat source. It is for supplemental heat only. • Risk of electric shock! DO NOT OPEN! No user-serviceable parts inside! • NEVER modify this heater. Doing so could result in personal injury or property damage. Modification of this fireplace completely voids all warranties. • ALWAYS turn this heater off before unplugging it from the outlet. • ALWAYS disconnect this unit from the power supply before performing any assembly or cleaning, or before relocating the electric fireplace. • NEVER leave this heater unattended. ALWAYS unplug this heater when not in use. • ALWAYS store this heater in a dry location. NEVER use the fireplace if it has become wet. • ONLY use this heater on a 120V AC 15-Amp or 240V AC 15- Amp circuit. NEVER overload the circuit. If this heater trips the circuit …

If the transmitter complies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. 8.4.3 Test Configuration Test according to clause 7.1 radio frequency test setup 1 8.4.4 Test Procedure The transmitter output (antenna port) was connected to the spectrum analyzer  Reference level measurement Establish a reference level by using the following procedure: Set instrument center frequency to DTS channel center frequency. Set the span to ≥ 1.5 times the DTS bandwidth. Set the RBW = 100 kHz. Set the VBW ≥ 3 x RBW. Set Detector = peak. Set Sweep time = auto couple. Set Trace mode = max hold. Allow trace to fully stabilize. Use the peak marker function to determine the maximum PSD level. Note that the channel found to contain the maximum PSD level can be used to establish the reference level.  Emission level measurement Set the center frequency and span to encompass frequency range to be measured. Set the RBW = 100 kHz. Set the VBW =300 kHz. Set Detector = peak Sweep time = auto couple. Trace mode = max hold. Allow trace to fully stabilize. Use the peak marker function to determine the maximum amplitude level. Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding restricted frequency bands) are attenuated by at least the minimum requirements .
