Operation; Turning On And Off - Acom 1000 User Manual

4. OPERATION

Operation of the amplifier is simplified due to the TRI tuning aid, Auto-Operate function, and automatic
protection system, so you'll 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.
There are 14 ON LINE information screens, which can be selected by pressing repeatedly the NEXT or PREV
buttons (see
Figure 3-2 Information Screens and Control Functions Structure
are described in next Sections

4.1. Turning ON and OFF

In order to turn on the amplifier, while the Main Power Switch (located on the rear panel) is on, press the
ON/OFF button (on the front panel right-bottom corner) and hold it on for about one second. The ON/OFF
LED indicator above the button will change from red to green. You'll hear the blower start first at high
speed, then slow down.
After successfully passing the initial self-tests, the ON/OFF LED begins flashing green while the following
inscription on the OLED remains lit:
(nnn above is the number of seconds remaining to readiness for operation)
A tube warm-up period of 2.5 minutes follows. During this time the amplifier remains in standby mode, so
you can continue operating with the transceiver.
Pressing either the PREV or NEXT buttons during this period will result in changing the screen to one of the
14 available information screens described in (see Section
) below. This action will not influence the warming-up process, so you may pass through all
Functions
information screens, for instance to monitor the High Voltage value or the Exhaust Air temperature. You
can also return to the old one to see how many seconds are still needed for the tube's heater.
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.
