Tokyo Hy-Power HL-2.5KFX Instruction Manual page 2

1. Introduction
Thank you for purchasing the HL-2.5KFX. This compact and lightweight
desktop HF linear power amplifier has a maximum input power of 2.9 kW. Our
solid-state broadband power amp technology makes it the smallest and lightest
in the industry.
Typical output power is 1.5 kW PEP/SSB with the drive power of 85-90 W. The
built-in band decoder will let you forget about the band setting when the amplifier
is connected to your modern radio through such band data cables as ICOM CI-V,
DC voltage (ICOM, Yaesu), and RS-232C (Kenwood). All the data cables are
included in your amplifier for your convenience.
2. Cautions
2-1 Unpack the amplifier, check the fan guard at the rear panel Fan to see if
there is any damage caused by the physical shock during the transportation. Fan
blades must be free to rotate when powered.
The amplifier is cooled by forced airflow. Several inches of clearance on the top
and the rear wall are necessary to allow for smooth air intake into the fan. Do not
block the air vents on the top cover.
2-2 Keep the amplifier out of direct sunlight, in a cool dry environment.
2-3 Internal high voltages, (AC, DC and RF), are present at all times, ON
AIR or OFF. Internal access should be limited to avoid injury.
2-4 Turn off the AC main power immediately upon any unusual sounds,
sights or odors. Check the multimeter readings of Vd and Id, the fuses and all
cable connections around the amplifier. Please notify the dealer or the factory of
any problems.
2-5 For your safety, do not operate the amplifier without adequate grounding.
A proper ground connection will result in peak performance and stability, in
addition to reduced RF strays or noises.
2-6 To eliminate the RF interference to such home appliances as TV, FM
radio, telephone sets, etc., it is recommended that clamp-on ferrite cores be
