Henry Radio TEMPO S30 Operating And Maintenance Instructions

TEMPO S30 OPERATING AND MAINTENANCE INSTRUCTIONS
INTRODUCTION
The Tempo S30 is a nominal 30 watt output, 1.5 watt drive RF amplifier
designed to mate with the Tempo S1 hand held, or any 1 to 5 watt drive por-
table transceiver. It operates in the 144 to 148 MHz 2 meter amateur band.
The S30 comes with a drive cable which mates with the S1, and a 3 foot fused
DC cable. The small size of the amplifier makes it easy to install, yet it has
enough heat sink to operated reliably and cool.
UNPACKING AND INSTALLATION
The S30 was tested at the factory at 144 to 148 MHz. Further alignment may
be necessary to match the antenna in your installation. Please read the align-
ment procedure carefully to prevent damage to the amplifier. If the amplifier
is Operating at its nominal output, no alignment is necessary. The solid state
devices in the amplifier are easily damaged if they are serviced incorrectly. The
equipment warranty can not cover damage caused by negligent service. We
recommend that all service be accomplished by a knowledgeabie technician.
Remove the amplifier from its shipping box and packing and examine it for
visible damage. If the amplifier was damaged in shipping, save the box and
packing and notify the transportation company immediately. Do NOT put
the amplifier into service if it has been damaged.
The following accessories should be included with the S30. A 6 foot drive
cable terminated on. one end with a UHF connector, and on the other end with
a mini phono plug. Also included are a 3 foot fused DC plug, a warranty card,
and an instruction sheet. When installing the S30, keep in mind that the equip-
ment should be mounted as closely as possible to the 13.8 VDC power source
to prevent low output caused by a voltage drop in the DC cabie. We recommend
installation inside the vehicle for mobile installations. The red power lead con-
nects to the battery's positive (+) terminal and the black DC lead connects
to the battery's negative (-) terminal. The diagram below shows the necesary
connections.
The DC power cables should be connected directly across the battery to prevent
damage to the ignition system of the vehicle caused by the high operating
current of the amplifier. Mount the amplifier at the desired location and plug
the DC cable into the 2 pin Jones plug on the amplifier.
