4. OPERATION
Operation of the amplifier is simplified due to the TRI (True Resistance Indicator) tuning aid,
AUTO-OPERATE function, and Automatic Protection System, so you will be able to begin using the amplifier
immediately after the installation.
However, to make full use of amplifier's potential and to fully configure it to your local conditions, we
recommend that you thoroughly read the following information.
4.1. Turning ON and OFF
In order to turn on the amplifier, press the power switch marked "
ON " (see
Figure 3-1 Front panel - Display
and Controls
to ON position (see
Figure 2-2 Power rocker switch in OFF or ON position)
. The LED indicator above
the switch will glow green and the audible cooling fan will start.
Following a series of automatic self-tests, the
OPER LED will begin to flash green and will continue to do so
during the 150-second warm-up period. Throughout this period, the amplifier will remain in the STANDBY
mode, and the transceiver may continue to be used.
Also, during this period, the
A1-A2 button may be pressed to change antennas, i.e., between the antennas
connected to the ANT1 and ANT2 outputs (see
Figure 2-1 Rear panel - Connections
, Pos. (c)). Switching
between the antennas does not affect the warm-up process.
NOTICE
To avoid damage not covered under warranty, do not change the antenna output during
a transmission, i.e., never press the
A1-A2 button when transmitting.
When you intend to have a short operating break, it is better to leave the amplifier in
standby mode instead of turning it off. Tube life is shortened by repeatedly turning on
and off the tube heater supply. However, if you unintentionally power-off the amplifier,
it is best to switch it on again immediately. When the pause is short (up to one minute)
and the cathode is still warm, the warm-up period is shortened significantly, which
reduces the waiting time and prolongs the tube's expected life.
After the warm-up period is complete, the
OPER LED stops flashing and remains illuminated green.
