Menu “Measurements in the amplifier” – AMP MEASURE
The menu AMP MEASURE (Fig. 5-1) is accessible from the MENU SELECTION screen (Fig. 5) in all modes. It is
possible to measure digitally 11 parameters in it, characterizing the amplifier operation and its regime.
Fig. 5-1 Menu “Measurements in the amplifier” – AMP MEASURE
Two identical lists appear on the left and the right halves of the screen, each one having the 11 parameters,
whose values are refreshed continuously.
An arbitrary parameter can be selected in each screen half. Using buttons ITEM1 and ITEM2 (up and down) select
the desired item (parameter) – it will be marked with color. Upon reaching either the top or bottom edge of any
half-screen, further movement in the same direction will cause the screen to scroll up or down, respectively, so
you can reach all the items in the list. The two marked parameters will be indicated continuously in the digital
measurements area on the basic screen (S. 3-2(b), Fig. 3-2) - after leaving this menu (EXIT button).

Menu “Service functions in the amplifier” – AMP SERVICE.
The amplifier service menu (Fig. 5-2) is accessible from the MENU SELECTION screen (Fig. 5) only during
reception (RX mode).
C A U T I O N
The AMP SERVICE menu is used for check and adjustment of the zero-
signal (idling) drain current of the final transistors and for tests of some
functions and circuits in the amplifier during repair as described in the
Technical compact disk (CD – option to the amplifier). We recommend

procedures are carried out only by a trained service technician!
With the ITEM buttons (up and down) the necessary service function is selected – it is colored. With the SELECT
buttons (left or right) the selected function or test item is turned ON or OFF.
The inactive functions are grey and the active - red. At leaving a function, its parameters are turned off and
deactivated automatically. Pressing the EXIT button all service functions (except for the OPERATE ACCESS) are
turned off (deactivated), menu AMP SERVICE is abandoned, and the MENU SELECTION screen comes back
(Fig. 5). At another pressing of the EXIT button, the basic screen returns (Fig. 3-2).
