Remove all components from packaging and lay them flat on a smooth, clean work surface. Remove all packing materials and uncoil the 48 ft string light (A). Take care not to nick or cut the cord or damage pre-installed bulbs. 2. Confirm all 24 (or 32) pre-attached bulbs are fully tightened into each socket of string light (A). Twist each bulb (C) clockwise gently to secure; do not over-tighten. 3. Connect the male plug of the string light (A) to the female plug of the dimmer controller kit (B). Push firmly to lock the connection. 4. Thread mounting hardware through the eyelet holes on each suspended socket to securely fasten the string light (A) to your support structure. Cable ties are included for mounting(E). 5. Plug the dimmer controller kit (B) into a rated 120 V AC power outlet. 6. Install AAA batteries into the remote controller (D). Match the positive (+) and negative (-) markings inside the battery compartment. 7. Use the control buttons on the dimmer kit (B) for basic ON/OFF operation. Use the handheld remote (D) to control power, brightness and timer functions. REMOTE CONTROLLER FUNCTIONS 1. Pairing & Control Range: Connect string light (A) and dimmer controller (B), then plug the dimmer kit into power to turn on the light string. The remote is factory-paired to only one matching light string set and cannot control separate light strings. 2. Brightness Control: The light features 5 preset brightness levels: 20%, 40%, 60%, 80%, and 100%. Press the +/- brightness buttons to adjust the brightness level. The light will flash once when the maximum brightness (100%) or minimum brightness is reached. Press and hold the +/- buttons for stepless dimming. 3. Timer Function: The light flashes twice when a timer duration (2H/4H/6H/8H) is set successfully. Timer cancellation: Press the Cancel Timing button; the light flashes once to confirm the timer function is turned off. FCC Statement This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device shall not cause harmful interference; (2) This device must accept all interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the compliance responsible party will void the user’s legal authority to operate this equipment. Note: This equipment has been tested and complies with the limits for a Class B digital device under Part 15 of the FCC Rules. These limits provide reasonable protection against harmful radio interference in residential installations. This equipment generates, uses, and radiates radio frequency energy. If not installed and operated per the written instructions, it may cause harmful interference to radio communications. There is no guarantee interference will not occur in a specific installation environment. If this equipment creates harmful interference to radio or television reception (verifiable by power cycling the unit ON/OFF), users may resolve interference using one or more of the following solutions: 1. Reorient or relocate the receiving antenna of your radio/TV device. 2. Increase the physical separation distance between this light set and the radio/TV receiver. 3. Connect this equipment to a power outlet on a separate electrical circuit from the receiver’s outlet. 4. Contact your product dealer or a professional radio/TV service technician for support. This device has been evaluated to satisfy general RF exposure requirements. The unit may be used under portable exposure conditions without usage restrictions. ADDITIONAL CAUTIONS & WARNINGS 1. The dimmer controller only supports 120 V AC power supply. Do not connect to any other voltage power source. 2. When using the remote controller for the first time, confirm AAA batteries are correctly installed with matching polarity (AAA batteries not included). 3. Disconnect power supply before connecting extension cords or installing bulbs into empty sockets. 4. Never operate the light string with empty, uncovered lamp sockets. 5. Do not connect or disconnect cord connectors during rainy, damp or inclement weather to prevent electric shock.

RF Exposure Estimation EUT Specification LMY-TVRC-RF-14K (FCC ID: 2BW3A-LMY-TVRC ) is operating at 433.92MHz. 1. Limit and Guidelines on Exposure to Electromagnetic Fields According to 4.3 General SAR test exclusion guidance of KDB 447498 RF Exposure, no SAR required if power is lower than the flowing threshold: The 1-g 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 calculation25 • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 5) in section 4.3 is applied to determine SAR test exclusion. 2. Calculation method [(max. power of` channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 According to ANSI C63.10-2013 (9.5 Equations to calculate EIRP), Measurement Result For 433.92MHz. Field Strength (EMeas): 77.44 (dBuV/m) (f=433.92 MHz) Measurement Distance(dMeas): 3 (m) Equivalent Isotropically Radiated Power(EIRP): -17.72dBm (0.0169mW) Radiated Power + tune up tolerance = 0.169mW Distance = 5 mm f = 433.92MHz [0.0169/5] * √(0.43392) =0.022265≤ 3.0 Therefore, excluded from SAR testing.
