A. SELLER liability under this Warranty is limited to repairing or replacing, at its option, any product
delivered not conforming to this Warranty;
B. This Warranty is limited to a period of three years;
C. Minor deviations from specifications that do not affect performance are excluded from this Warranty;

Safety Instructions
Safety Instructions
To maximize user safety and ensure correct device operation, all instructions con-
tained in this section should be read carefully.
Before Applying Power
Verify that the line voltage is 115VAC.
Ground the Exciter
To minimize shock hazard, the exciter chassis must be connected to an electrical
ground, the exciter must be connected to the AC power mains through a three-con-
ductor power cable, with the third wire connected to an electrical ground (safety
ground) at the power outlet. Any interruption of the protective (grounding) con-
ductor or disconnection of the protective earth terminal will cause a potential
shock hazard that could result in personal injury. If the exciter is to be energized by
any other source be certain that the chassis is connected to a separate safety
ground.
Caution: It is important that the user observe all warnings and instructions that
are on the device and contained in this manual.
Warning: DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Operation of the FM150ES in the presence of flammable gasses or fumes can
endanger persons proximate to the site of operation.
Caution: NO NOT REMOVE THE EXCITER COVER
Removal of the exciter cover will invalidate the FM150ES Warranty. Compo-
nent replacement and internal adjustments must be made only by PTEK quali-
fied service personnel.

vi PTEK Corporation
FM150ES Operating Manual and User Guide
Fuses
Only fuses with the same required current, voltage rating, and specified type (nor-
mal blow, time delay, etc.) should be used. Do not use repaired fuses or short-cir-
cuited fuseholders. To do so could cause a shock or fire hazard.
Output Connector
Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive devices
or micro-circuitry. Proper packaging and grounding techniques are necessary pre-
cautions to prevent damage. Always take industry-standard precautions.
Grounding Methods
Guard against electrostatic damage at workstations by following these steps:
1. Cover workstations with approved anti-static material. Provide a wrist strap connect-
ed to a work surface and properly grounded tools and equipment.
2. Use anti-static mats, heel straps, or air ionizers to give added protection.
3. Handle electrostatic-sensitive components, boards, and assemblies by the case or the
PCB edge.
4. Avoid contact with pins, leads, or circuitry.
5. Turn off power and input signals before inserting and removing connectors or test
equipment.
6. Keep the work area free of non-conductive materials such as ordinary plastic assem-
bly aids and Styrofoam.
7. Use field service tools, such as cutters, screwdrivers, and vacuums that are conduc-
tive.
Warning: The type-N output connector carries dangerously high RF voltages
that present shock and burn hazards. Never operate the FM150ES exciter with-
out properly terminating the output connector in either an adequately rated load
or antenna.

Safety Instructions
General Safety Rules
• The device must be used in accordance with the instructions for use.
• Electrical installations in the room must correspond to the requirements of respective regu-
lations.
• Take care that there are no cables, particularly mains cables, in areas where persons can trip
over them.
• Do not use a mains connection in sockets shared by a number of other power consumers. Do
not use an extension cable.
• Only use the mains cable supplied.
• The unit is completely disconnected from the power source only when the power cord is dis-
connected from the power source. Therefore the power cord and its connectors must always
remain easily accessible.
• Do not set up the device in the proximity of heat sources or in a damp location. Make sure
the device has adequate ventilation.
• All plugs on the connection cables must be screwed or locked to the chassis housing.
• The device is designed to be used in horizontal position only.
• The device is no longer safe to operate when the device has visible damage or the device no
longer functions.
• In case of system malfunction or visible damage to the FM150ES, the device must be shut
down and secured against unintentional operation.
• Repairs may only be carried out by a person authorized by PTEK LLC.
• If extensions are made to the FM150ES, the legal stipulations and the device specifications
must be observed.
• The FM150ES must be switched off when removing the top cover.

Preface
This document, entitled FM150ES Operating Manual and User Guide, provides
instructions on how to install, configure, power up, and perform diagnostics on the
150-watt PTEK FM150ES FM Stereo Broadcast Transmitter (see photo below), an
easy-to-use and versatile system that can be used in either stand-alone or backup
mode. The information contained within is intended for an experienced system oper-
ator with a knowledge of high-performance broadcast transmission systems.
The 2RU-high (3.5”) FM150ES is designed to fit a standard 19” rack and is provided
with rack-mount left and right brackets and handles. Optional rack-mount slides are
also available. The FM150ES is rugged enough to withstand extreme shock (up to
5G), temperature (up to 50°C), and EMI such as that associated with broadcasting
from remote rugged environments.
FM150ES FM Stereo Broadcast Transmitter

xiv PTEK LLC
FM150ES Operating Manual and User Guide
Key features of the FM150ES FM Stereo Broadcast Transmitter include:
• Totally solid-state no-tune construction
• Wide input range from 88 to 264 VAC
• 3-year warranty on all parts and labor
• Built-in field-programmable FSK ID for translator use
• Remote-control interface
•Optional built-in stereo encoder
• Rugged design withstands up to 5G forces and 50°C
• Meets or exceeds all FCC and CCIR standards
• Designed and manufactured in the United States
The FM150ES is FCC-certified for use on LPFM stations. Frequency stability for
each unit is ensured by using PLL (phase-locked loop) frequency synthesis from a
highly stable crystal oscillator. All units incorporate over-temperature protection and
VSWR foldback to automatically reduce power output to safe operating levels.
Switch-mode power supplies provide consistent performance even when there are
frequent power outages and voltage fluctuations that make stressful demands on
power dependence.
An overview and specifications of the FM150ES FM Stereo Broadcast Transmitter
is given in Chapter 1, "Overview and Specifications", of this manual.
