5. Operations:
5.1. Display Explanations of LCD
a; LCD displays 16 characters a line, totally two lines.
b, Parameter name is in the first line; value is in the second line.
After plugging in to the suitable power socket this set will automatically
delay 7 seconds before opening RF amplifier. Shows as follow:
5.2. Press middle key:
Changing the amplitude of RF driving signal then change the modulation depth
of laser and can using the lift key and right key to decrease and increase
it.
Amplitude of RF Amplifier working status
(There is RF signal) (If there is no RF signal)

Note1:
If no RF signal it will display “no RF signal” as fellow lift finger. Otherwise
LCD will display the amplitude of RF signal as fellow right finger.
Totally 16 words“>”,User may adjusting the RF amplitude by press the lift
Or right key (see 7.4) according to the number of TV channels transmitted
And the parameter of your system to enables superior link optimization and
Variable modulation depth (RF drive level).
