Getting Started:
Please study carefully the “IMPORTANT SAFETY INSTRUCTIONS” that are given on page 4 before applying power
to your AMFM1 tuner.
This unit was carefully checked and packed before leaving the factory. However, it is always a good idea to inspect
the shipping container and unit for indications of improper handling . If the unit has been damaged, make an
immediate claim to the dealer or distributor from whom it was purchased . If the unit was shipped to you, notify the
transportation company without delay, saving all packing materials, in order to process the claim.
INSPECTION
Before installing the tuner, continue the inspection by running a quick performance check . Connect an 8
W test
speaker to the 8
W music-on-hold “MOH OUT” output terminals, attach the FM wire antenna, and set the controls for
operation. MAKE SURE THE UNIT IS GROUNDED BEFORE TESTING. In this way you can check the basic
operation of the AMFM1 before actually installing the unit and making all of the final terminations required for the
permanent installation. If shipping damage has resulted in the tuner being inoperable out of the box, call Lowell
Customer Service to arrange for a replacement.
INITIAL PERFORMANCE CHECK
MOUNTING THE TUNER
The AMFM1 may be placed on a wooden or metal wall-mount shelf. For shelf mounting, attach the provided stick-
on rubber feet to the bottom of the AMFM1 chassis. Rack mount ears are built-into the front panel of the AMFM1,
so the unit may be mounted in a Lowell equipment cabinet using standard 10-32 Phillips-head machine screws (like
the Lowell model RS or RSP rack screws) with integral plastic washers to protect the finish of the front panel of the
AMFM1 tuner.
WARNING: THIS AMFM TUNER
MUST BE EARTH GROUNDED.
The AC power cord provided with this tuner is equipped with a North American style NEMA 5-15P plug and the AC
VOLTAGE SELECT SWITCH (see item on page 3) is set to operate on a 115 VAC 50/60 Hz. power source. The
AMFM1 may also be powered with 12VDC (
See the DC current requirements under “DC SUPPLY VOLTAGE” in the
“TECHNICAL SPECIFICATIONS” section on page 1). If this unit is to be used in other geo-political areas of the
world, it may be necessary to change the AC SUPPLY SWITCH to operate on 230 VAC. Remove the black screw
below “VOLTAGE SELECT” on the rear panel and push the switch in using a small diameter insulated tool .
Remove the plug from the end of the cord and replace it with one appropriate for the local power grid receptacle
standards. The internal wire color code for the cord supplied with this unit is as follows :
Green/Yellow
Earth “E” or Safety Ground
Blue Neutral “N”
Brown Line “L” or Hot
Note: If a British Standard BS1363 plug is installed, it must be provided with a 5 Amp fuse.
Since electrical color codes vary around the world, make sure that the correct connections are made to the cord
even if the local color code is different. If in doubt, obtain the services of a locally qualified electrical professional.
POWER WIRING
MAIN OUTPUT CONNECTIONS
The AMFM1 dual mono output connections are RCA phono jacks . Connecting output cables
should be wired with the pin “hot” or “+” and with the sleeve “common” or “-”. The stereo cable
