15. INSTRUCTION MANUAL HF LINEAR POWER AMPLIFIER MODEL HL 2 5K TOKYO HY POWER 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
