Frequency and power adjustment
The three keys
Basically there are three push-buttons available for the menu system;
UP
,
DOWN
and
MENU
. By
pushing
UP
or
DOWN
you get a shift of frequency in corresponding direction. Hold any of these
keys for a few seconds and the jumps will increase to 500 KHz. The new frequency is saved
automatically. The third button (
MENU)
gives you an option to select and setup other functions of
this unit.
The menu system
The UP and DOWN keys are used to change parameter values. In normal mode the LCD simply
shows the frequency and power or whatever view you select. Menu key can be used to enter the menu
mode, repeatedly pressing this key brings up the following menus: <RF POWER>, <STEREO
MODE>, <VIEW SELECT>. Pressing the UP or DOWN key selects the desired parameter and
allows you to modify its value. Another press on the MENU key and you’re back to the normal mode.
Note that all these settings except power and frequency are already set as they should be so changing
them should not be necessary and is not recommended.
Changing frequency
Simply press the UP/DOWN button to change frequency. If you keep pressing a key for a while the
PLL STEP switches to fast tuning mode and jumps in 500KHz steps.
<RF POWER>
This setting allows you to set output power. Select desired power with the UP/DOWN keys and press
MENU key to exit the menu system and return to normal operation. Selected power is displayed on
the LCD as a line of bars. Think of this setting as an accelerator (gas) pedal in your car. Think of the
power in watts that is shown on the LCD as the speed meter in your car. Depending on the road going
uphill or downhill speed meter will show different values even if your accelerator pedal is fixed in the
same position. If you go downhill your speed will be greater with same amount of gas pedal. Likewise
here your supply voltage can affect the actual output power slightly.
<STEREO MODE>
You can set your transmitter to MONO or STEREO here.
