WARNING
Before connecting the amplifier to your line (mains) supply, be sure that the line (mains) supply is correctly
wired and is capable of providing the required current, i.e., up to 5 A from 240 V and 10 A from 120 V. As
discussed earlier, it is very important that the ground lead is adequately sized and properly connected.
The Power Switch on the front panel must be in the OFF position; only then should you insert the amplifier's
line (mains) plug into the appropriate wall outlet. At this time the amplifier remains switched off.
3. POWER ON, CONTROLS AND INDICATORS
CAUTION
Do not turn the amplifier on for at least 2 hours after unpacking it and locating in its operating location. Pay
particular attention whenever the amplifier is moved from a very cold place to a very warm one because
unseen condensation may develop, and this could result in damage to the high voltage circuits of the
amplifier. Under these circumstances, do not turn the amplifier on for at least 4 hours. A similar effect could
occur following rapid warming of the location, such as winter use of a powerful electric heater.
CAUTION
To avoid damage that may not be covered by the amplifier warranty, carefully check that the voltage for
which the amplifier is set corresponds to your nominal line (mains) voltage. See Section 2-2 and Table 2-1.
After following all instructions in Section 2, you may now turn ON the main POWER switch on the front
panel (Fig. 3-1). The green LED indicator above the switch will illuminate:
Fig. 3-1 ACOM1011 Display and Control
Note that the upper LED bar-graph always reads peak forward power, except for the service functions
(Section 5-5). The 800 W-scale resolution is 50 W. Note also that levels below 50 W may be not detected.
The lower LED bar-graph will indicate reflected power up to 240 W. The scale resolution is 30 W.
The OPER button alternatively switches between the operate and standby modes once the amplifier has
completed its 30-second warm-up period. See Section 4-2.
The RTTY button reduces the output power of the amplifier to 500 W. See Section 4-3.
