INTRODUCTION
This service manual describes the latest service information
for the IC-PW1 HF/50 MHz ALL BAND LINEAR AMPLIFIER
and the PX-1981 POWER SUPPLY UNIT at the time of
publication.
To upgrade quality, all electrical or mechanical parts and inter-
nal circuits are subject to change without notice or obligation.
DANGER
THE IC-PW1 include an AC power supply. Therefore,
NEVER touch the PX-1981 unit while the linear amplifier
is connected to an AC outlet, otherwise an electric shock
may be received. An insulated tool must be used at all
times.
Use
ONLY the specified AC voltage labelled on the AC
power socket of the IC-PW1. Other voltages could cause a
fire hazard.
THE IC-PW1 IC accepts 13.8 V DC ONLY. NEVER con-
nect to an AC outlet. Such a connection could cause a fire
hazard and/or electiric shock.
DO NOT expose the linear amplifier to rain, snow or any
liquids.
NEVER carry the linear amplifier by yourself. At least
two persons must carry the linear amplifier since it weights
approx. 25 kg (55.12 lb).
