Operation; Turning On And Off - Acom 1500 User Manual

a) You can use the OFF LINE information screens and control functions. They refer to the
auto-protection signatures list, Display brightness control, as well as the Auto-Operate
feature. This is described in S5.
b) You can turn on the amplifier and start the warm-up sequence. After 3 minutes you may
tune and begin operating the amplifier and you can use the ON LINE information screens or
control functions (see below).

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 I4 ON LINE information screens, which can be selected by pressing repeatedly the
NEXT or PREV buttons (see fig.3-2). Their purpose and method of use are described in the
next five sections 4-1 through 4-6.

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 red ON/OFF button (located under the red LED on the front panel right-bottom
corner) and hold it on for about one second. The VFD will light at full brightness and the
ON/OFF LED indicator above the button will change the color from red to green. You'll hear
the blower and the optional external fan starting at high speed for a second, then slow down.
After successfully passing the initial amplifier self-tests, the ON/OFF LED begins flashing
green while the following inscription on the LCD remains lit:
WARMING UP: nnn s
(nnn above is the number of seconds remaining to readiness for operation)
A tube warm-up period of 180 seconds (3 minutes) follows. During this time the amplifier
remains in standby mode, so you can continue operating with the transceiver.
