Before connecting the amplier to your mains supply, be sure that the

supply is correctly wired, and is adequate for the current drawn by the

amplier. Make certain that the grounding lead is connected properly in

the wall outlet for the amplier.

It is preferable that you use the wall outlet closest to the source. The installation leads should

be at least 2.5mm

(AWG 12 or SWG 15). Check if the respective fuses can handle current up

to 20A, as well as if the voltage corresponds to the voltage for which the amplier is set (S.2-2).

If you connect the amplier to a different mains outlet, be sure that you check it, too.

Make sure the main Power Switch on the front panel is in OFF position (so that the red strip on

the switch is hidden) and insert amplier's mains plug into the wall outlet prepared for it. The

amplier remains switched off.

2-5. Installation of Optional Fan

This fan is not necessary in SSB and CW modes, nor in continuous carrier modes (RTTY, SSTV

etc.) with carrier down times of maximum 15 minutes and a subsequent pause of 3 minutes. For

higher duties the fan is recommended. The auxiliary fan (119x119mm) is supplied as an option

with a set of 8 screws, nuts and washers. It may be mounted by the manufacturer or dealer

on request (Fig. 2-2). Contact your dealer or see the TECHNICAL SUPPLEMENT for details.

3. POWER ON, RCU CONTROLS, INDICATORS AND MENUS

C A U T I O N

Before you turn the amplier on, at least 2 hours should have expired since

it was brought in and unpacked in the room where it will be used. Pay

particular attention when you move it from a very cold into a very warm place

- condensation is likely and this could result in damage to the high voltage

circuits. In such a case, wait at least 4 hours. A similar effect can occur after

a rapid warming of the operating room (for instance after switching on a

powerful heater).

C A U T I O N

To avoid damage (not covered under warranty) carefully check that the voltage

for which the amplier is set corresponds to your mains nominal voltage (see

S.2-2 and table 2-1).

After following all instructions in S.2, you can turn ON the Main power switch on the front

panel. The red LED indicator above it must light and a picture will appear on the RCU (Fig.3-

1):
