This will allow the front of the clock to separate from the back case section of the clock. The back case is the portion that will be mounted to the wall first. Make sure that both the clock and the back case are facing in the upright position before moving on to the next steps. w Mount the back case and mounting cap to the switch box - Make sure that the mounting cap is slid into place on the back case. *Note: the mounting cap should slide on to the top side of the clock. Pull all necessary wires from the switch box through the hole in the back case and mounting cap (9”- use the top hole, 12” or 16” - use either the top or second to the top hole). Line up the two holes in the back case of the clock and the mounting cap with the two holes that line up with the top and bottom of the switch box. Note: the back case of the clock and the mounting cap are provided with holes that line up with the holes on a double switch box as well - these holes are located on the four outter most holes of the back case and the mounting cap. Using the 6-32x1" screws included in the supplied kit, screw the back case and mounting cap to the switch box. e Plug and secure wiring - Take the wiring that should now be routed through the switch box and through the hole in the back case and mounting cap and secure it to the back case by slipping it under the clamps or tabs located within the back case. The user will choose the clamps and tabs used based on the amount of excess wiring present inside the back case. Take the front of the clock that was separated from the back case in step 1 and plug the end of the wiring into the appropriate jack on the movement. r Attach the front of the clock to the back case - With the wiring now secured and properly plugged into the movement, take the front of the clock and snap it back together with the back case. Press the front of the clock into the back case, making sure the tabs that were disengaged in step one are properly snapped back together. Note: when pressing the front of the clock onto the back case, DO NOT press on the center of the clock. Rather, push on the outer edges of the frame of the clock as to not damage the contents of the clock.

Antenna Description The Sapling Company, Inc. FCC ID: R73LPA1 The quarter wave monopole antenna is a single element antenna fed at one end, that behaves as a dipole antenna. It is formed by a conductor ¼ in length. It is fed in the lower end, which is near a conductive surface which works as a reflector. The current in the reflected image has the same direction and phase as the current in the real antenna. The quarter-wave conductor and its image together form a half-wave dipole that radiates only in the upper half of space. In this upper side of space the emitted field has the same amplitude of the field radiated by a half-wave dipole fed with the same current. Therefore, the total emitted power is one-half the emitted power of a half-wave dipole fed with the same current. As the current is the same, the radiation resistance (real part of series impedance) will be one- half of the series impedance of a half-wave dipole. As the reactive part is also divided by 2, the impedance of a quarter wave antenna is (73 + i43) / 2 = (36 + i21) ohms. Since the fields above ground are the same as for the dipole, but only half the power is applied, the gain is twice (3dB over) that for a half-wave dipole ½, that is 5.14 dBi.

FCC ID: R73LPA1 Page 3 of 34 General Test Requirements 1. The measurement procedures of ANSI C63.4:2003 were utilized as specified in FCC Part 15, Subpart C, Section 15.31(a)(3). 2. All radiated emissions measurements were performed on an Open Area Test Site (OATS), listed with the FCC, in accordance with FCC Section 15.31(d). 3. The level of the RF power output was measured with the AC input varied from 85 to 115% of rated. The worst case results were reported in accordance with FCC Section 15.31(e). 4. All radiated emissions measurements were performed at the specified 3 meter test distance as required by FCC Section 15.31(f). 5. The EUT was rotated throughout 360 degrees for all radiated emissions measurements as specified in FCC Section 15.31(f)(5). 6. All readily accessible EUT controls were adjusted in such a manner as to maximize the level of emissions in accordance with FCC Section 15.31(g). 7. Appropriate accessories were attached to all EUT ports during the performance of radiated emissions measurements as required by FCC Section 15.31(i). 8. AC line conducted emissions were measured utilizing a 50 Ohm / 50 MicroHenry LISN as specified in FCC Section 15.31(l). 9. The EUT operated over the frequency range of 914 to 928 MHz. A total range of 14 MHz. Testing was performed with the device operating at 3 frequencies, 1 at the top, 1 in the middle and 1 at the bottom of the range of operation in accordance with FCC Section 15.31(m). 10. The frequency spectrum was investigated from the lowest frequency generated in the device up to the 10 th harmonic of the highest fundamental frequency in accordance with FCC Section 15.33(a)(1). 11. Measurements below 1000 MHz were taken utilizing a Quasi-Peak Detector. Measurements above 1 GHz were taken utilizing an Average Detector in accordance with FCC Section 15.35(a). The peak value of emissions above 1 GHz were verified to meet the 20 dB requirement of FCC Section 15.35(b). Retlif Testing Laboratories, Test Report R-1735P-2, The Sapling Company, Inc. FCC ID: R73LPA1 Page 4 of 34 Requirements and Test Results Requirement: FCC Section 15.203 Antenna Requirements An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier current devices or to devices operated under the provisions of §15.211, §15.213, §15.217, §15.219, or §15.221. Further, this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with §15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that the proper antenna is employed so that the limits in this part are not exceeded.  Results: This module, when integrated into the final product, is distributed and professionally installed through a dealer network, therefore the module is deemed compliant with FCC Section 15.203. Requirement: FCC Section 15.207(a) - Conducted Limits For an intentional radiator that is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies within the band 150 kHz to 30 MHz shall not exceed the limits shown in Table 1, as measured using a 50 μH/50 ohms line impedance stabilization network (LISN). Compliance with the provisions of the paragraph shall be based on the measurement of the radio frequency voltage between each power line and ground at the power terminal. The lower limit applies at the boundary between the frequency ranges.
