Fig.3-2 Information Screens and Control Functions Structure
The OPER button alternatively changes operate and standby modes (S.4-2) while ON LINE. Please note that Auto-
Operate might be enabled. The same button activates signature list while OFF LINE.
The PREV and NEXT buttons change information screens or select control functions (S.4-4) for both OFF LINE and ON
LINE.
The ON/OFF button alternatively switches OFF LINE and ON LINE states of the amplifier.
You can proceed in one of two directions:
a) You can use the OFF LINE information screens and control functions. They refer to the auto - protection signatures
list, LCD contrast and backlighting control, as well as the Auto-Operate feature. This is described in S5.
b) You can turn on the amplifier and begin the warm-up sequence. After 2.5 minutes you may tune and start 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 it immediately after the installation. However, to make full use of amplifier’s
potential and to fully configure it to your local conditions, we recommend 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 fig.3-2). Their purpose and method of use are described in the next five sections 4-1 through 4-5.
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 (on the front panel right-bottom corner) and hold it on for about 1 second. The LCD backlight will light and 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 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 2.5 minutes follows. During this time the amplifier remains in standby mode, so you can
continue operating with the transceiver.
