5-3. INFO (INFO BOX)

During operation of the amplifier, information is stored in the nonvolatile memory about the 12 most
recent protection trips or irregularities and the time when they have occurred (indicated as tubes
working hours). This information, along with other service data is also stored which can be transmitted
to the service center for use by remote diagnostics.
For transmitting the information, the standard BAUDOT code is used with the following parameters:
45.45Bd speed, AFSK, 170Hz Shift, 2295Hz Mark-tone, 2125Hz Space-tone. The signal is emitted
acoustically by the BEEP-indicator of the RCU and its strength is constant.
In order to transmit the signal, bring the microphone of the telephone near the RCU (or use other
convenient means) and in the OFF-MENU twice depress the button. Three identical transmission
cycles follow of about 1 minute duration each, or 3 minutes and 10 seconds total, during which you will
hear the typical RTTY sound from the RCU. The procedure can be interrupted at any time by pressing
the ESC button.
Using the DOS application (option) you can read the same information on the screen of a PC, save it in
a file, print it, or mail it via INTERNET (see S. 1-2).

5-4. LOCK

N O T E
If you use this feature be careful that you DO NOT FORGET THE CODE!
By following the instructions below, you can set a lock code to protect against undesired power-on of
the amplifier by other persons, for example by children.
Initially, the code characters are question marks, which indicates that no code is set (the manufacturer
does not set any code):
The lock code is a number with up to six figures which afterwards must be set by anyone who wants to
switch on the amplifier with the red button or to change the code.
The and buttons change the code figure selected by the brackets, while the and
buttons move the brackets among the different figure positions. It is not mandatory that you use six
figures, nor be they orderly. For example, the code could be 32???6 or 238935. After you have selected
the desired code, press the button.
In order to eliminate the code, select the LOCK sub-menu, enter the active LOCK-code, then set six
question marks instead of a code and press the button.
