Vertex Standard VX-2R Manual Do Utilizador

This process uses a programmed routine in the transceiv-

er which simplifies many previously complex discrete

component settings and adjustments with digitally-con-

trolled settings via front panel keys and LCD indications.
Set the transceiver to the 430MHz band, then turn the

transceiver off. Now, press and hold in the [F/W], [MD],

and [ ] keys (at the same time) while powering the radio

on again. The display will show the first setting. Thereaf-

ter, the frequencies used during alignment will automat-

ically be set without further action by the technician.
In the alignment process, each adjustment is selected by

rotating the DIAL knob. Alignment is performed by:

¦

Pressing the [V/M] key;

¦

Injecting a signal of the required frequency and level;

then

¦

Pressing the [V/M] key after a level setting or adjust-

ment is made. This second pressing of the [V/M] key

stores the alignment data at the desired value.

To exit the alignment routine, press the [HM/RV] key. Af-

ter performing the system alignment in its entirety, indi-

vidual settings can be returned to and adjusted should

the need arise.

r

Adjust the generator level to +20 dBµ (leaving the

modulation level unchanged from the previous step),

then press the [F/W] key.

r

Press the [F/W] key again, then press the [V/M] key.

r

Rotate the DIAL knob to select the next setting.

TX High Power (Low Band Edge @6.0 V) Adjustment (HHP)
r

Set the DC power supply voltage to 6.0 V.

r
