Limited Warranty
PTEK (SELLER) warrants that products are free from defects in material and workmanship and meet
performance specifications provided, however, that:
(A) SELLER’ liability under this Warranty is limited to repairing or replacing, at its option, any
product delivered here under not conforming to this Warranty;
(B) This Warranty is limited to a period of two years;
(C) Minor deviations from specifications which do not affect performance are excluded from this
Warranty; and
(D) SELLER shall be liable under this Warranty only if:
(1) It is promptly notified in writing by the Buyer upon discovery of the failure of any product to
conform to this Warranty,
(2) The product is returned to SELLER, transportation charges prepaid by the Buyer,
(3) The product is received by SELLER not later than ten days after the last day of the one-year
period of this Warranty, and
(4) SELLER’ examination of the Product discloses to SELLER’S reasonable satisfaction that
such defects or failures as may exist have not been caused by misuse, neglect, improper
installation, repair, alteration, accident or shipping.
The Buyer will prepay freight to and from SELLER on products serviced here under at SELLER’ plant; but
SELLER may, at its option, elect to perform any repairs here under at the Buyer’s place of business.
The foregoing constitutes SELLER’S entire Warranty expressed, implied and/or statutory, except as to
title, and states the full extent of SELLER’S liability to the Buyer or to any other party for any breach of
such Warranty and for damages, whether direct, special, incidental or consequential; and, other than as
expressly provided in this document. No Warranties, expressed or implied, including any Warranty or
merchant ability or of fitness for a particular purpose, are made. No employee, representative or agent of
SELLER has any authority, expressed or implied, to alter or to supplement the terms of this Warranty.
Warranty Service
The Limited Warranty covers parts and labor to the original purchaser for one year. Damage
caused by misuse or shipping is excluded from the warranty. Before returning units or material,
contact the factory for a Returned Material Authorization (RMA) number. Ship all material

Safety
BEFORE APPLYING POWER
GROUND THE EXCITOR.
Fuses
.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
DO NOT REMOVE THE EXCITOR COVER
Output connector
Verify that the line voltage is 115V
To minimize shock hazard, the excitor chassis must be connected to an electrical ground. the excitor must beconnected to the ac power mains through a three-conductor power cable, with the third wire firmly connected to anelectrical ground (safety ground) at the power outlet. Any interruption of the protective (grounding) conductor ordisconnection of the protective earth terminal will cause a potential shock hazard that could result in personal injury.If the excitor is to be energized by any other source be certain the that chassis is connected to a separate safetyground.
Only fuses with the same required current, voltage rating, and specified type (normal blow, time delay, etc.) should beused. Do not use repaired fuses or short-circuited fuseholders. To do so could cause a shock or fire hazard
Do not operate the power amplifier in the presence of flammable gases or fumes.
Operating personnel must not remove the exciter cover. Component replacement and internal adjustments must bemade only by qualified service personnel.
The type N output connector carries dangerously high RF voltages which present a shock and burn hazard.operate this excitor with out the out put connector properly terminated in either an adequately rated load or antenna.

2 OPERATE Switch and
Indicator
This switch sets the FM Broadcast Amplifier to the Operate Mode; 110 VAC is
applied to the line transformers and this amber indicator is lit.
3 REMOTE OFF Indicator This red LED indicator is lit when the FM Broadcast Amplifier remote off
terminals (rear panel) are open circuit.
3 DRIVE LOW Indicator This red LED indicator is lit when the FM Broadcast Amplifier can not make the
power requested, because for example low drive power.
5 FAULT Indicator This red LED indicator is lit when the FM Broadcast Amplifier is in a fault
condition. This can be for one or combination of the following:-
Over drive, High supply Voltage, High load VSWR, Over temperature.
6 Meter Select Switch This switch selects one of the following to be presented on the meter (1):-
Forward Power, Reverse Power, Final Voltage, Final Current and Deviation.
7 ADJ POWER control This control adjust the output power from rated full power to less than 50%.
8 Ventilation Filter This provides for filtering the environmental air as it is drawn into the cabinet by
the internal fan (not used on FM10E).
Refer to the Table below for the following description. The installer should assure the ac line voltage is turned OFFbefore performing this procedure. The electrical connections are installed at the Exciter rear panel.
Installation-Electrical
Step Procedure
1 Connect the load RF line to RF OUT connector.
3 Connect the ac line power to the ac line in connector.
4 Optional. Connect the remote site metering, to the rear terminal block.
5 Connect either the composite input to the output from a stereo encoder or the balanced mono input to a
program source
