Using the CyberMaxFM+ series transmitter
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 many of the options and DSP functions of this unit.
Lcd control module menu system: Power and DSP functions
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>, <TREBLE>, <BASS>,

<RIGHT CH VOL>, <LEFT CH VOL>, <PLL STEP>, <RF EQ>, <FIRMWARE VER>, <PWR/SWR METER>,
<TEMP ALARM>, <SWR ALARM>, <BAND SELECT>, and <RF AMP CONTROL>. 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. Depending on PLL STEP setting your frequency will go down in
5/10/25/50/100/200KHz steps. If you keep pressing a key for a while the PLL STEP switches to fast tuning mode and
jumps in 500KHz steps.
Note: Frequency changes also when you select a view type which does not show frequency, such as UPTIME.
<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.
