Connect the mains cable to the plug on the rear of the exciter.
NOTE: This device shall be correctly connected to ground.
Correct grounding is essential both for safety and to reach the rated performances.
Connect your source audio (for example the mixer or STL output) to the suitable
input connector. Depending on the version, the PTX-LCD offers a number of input
choices, L+R, MPX or even digital; see the connectors description for details.
5.3 Operation
Switch on the exciter with the mains switch on the front panel.
All the STATUS and ALARMS leds are lit on to permit the verification of their good
working status. The display than shows some information regarding the exciter.
After some seconds, the user is invited by the sound of a buzzer and by a message
on the display, to push the encoder if the current settings are not acceptable.
If the use pushes the encoder while the message is displayed, the exciter will start
in stand-by mode, that is completely working but with RF power disabled.
If the encoder is not pushed, the start-up sequence goes on undisturbed.
At start-up, the various modifiable parameters will be set as they were before the
machine was switched off (i.e., 98.00 % MHz and 0 % are just example values):
the current parameters are in fact always stored in non-volatile memory.
When the settings are not correct, for example at the first start up of the machine
or if for some reason it is necessary to change some parameters before starting to
transmit, it is possible to keep the exciter in stand-by mode, as seen above.
This operation is necessary only if one wants to modify the device’s settings before
starting transmitting.
