PREMIX WIRELESS FM-72 Operation Manual Section 1: FCC Information and Precautions: AD FCC Information and Requirements This device complies with part 90 of the FCC rules. Operation is subject to the following two conditions: (I> This device may not cause harmful interference, ond (2) This device must accept any interference that may course undesired operation.
PREMIX WIRELESS FM-72 Operation Manual Operation of the FM-72 Transmitter requires an operating license, Prior to operating the FM-72 transmitter, an application must be filed with the FCC and approval from FCC is required. Prior to receiving the FM=72 Transmitter, filing and FCC licensing should have been completed, if not, you must fill out and file the required application with the FCC.
PREMIX WIRELESS FM-72 Operation Manual without an antenna will destroy the transmitter circuit! Altering the antenna or case which serves as the ground plane for the antenna is prohibited by FCC regulations. FCC also requires tho the antenna be attached to the case and tho the antenna is vertical with respect to the earth, Static electricity can damage the FM-72 transmitter. Be sure tho you are grounded before touching the antenna or the case.

PREMIX WIRELESS FM-72 Operation Manual Section 3: Initial Setup: AD Transmitter Setup 1) Transmitter location The first step In setting of the FM-72 transmitter is to determine a suitable location for the transmitter. The transmitter requires 120 VAC and therefore it must be located near a 120 VAC outlet.
PREMIX WIRELESS FM-72 Operation Manual B> Clock setup (see figure page #8 Clocks for the FM-72 transmitters come fully assembled. They do require the installation of 2 “D” cell batteries, setting of the clock hands to the approximate time and the pressing of o red button to identify the position of the second hand ond the minute hand The procedure is as follows: 15 Insert two “D’ cell batteries into battery holder.
PREMIX WIRELESS FM-72 Operation Manual Section 4: Details of Operation: AD Transmitter Operation: The following assumes that the FM-72 transmitter and clocks have been properly setup as described earlier in this manual, When power is first applied to the FM-72 transmitter, it will display the Software revision number for o few seconds.

PREMIX WIRELESS FM-72 Operation Manual S50 If the “AM” or “PM” are displayed on the dial, then the 12 hour option was selected and is being displayed, If neither “AM” or PM’ is being displayed then the 24 hour was selected and is being displayed. For practical purposes the 24 hour mode switch only changes the display. Both the 12 & 24 hour modes support the 12 hour and 24 hour clocks. 60 GPS signal reception is indicated by the tower (it looks like ao “Y* with o line over it) and by the parentheses.
PREMIX WIRELESS FM-72 Operation Manual clock to that time. The FM-72 then starts to transmit its internal time once every second. The transmission signal is o one watt FM signal at approximately 72.
PREMIX WIRELESS FM-72 Operation Manual then the microprocessor will store the channel number, set the clock to the received time and then for the next minute the clock will beep every time that it receives a valid time signal, If the clock is in a good signal area it will beep once o second. [If the clock beeps every few seconds, then you are in a poor signal area, The clocks should work in these poor signal areas, but they will have a shorter battery life (est.
