Page 6: Things To Remember
Coaxial cable loss is measured in dB’s…decibels. 3 dB loss = 1/4 of your signal strength - either lost or gained. Watch out for the correct impedance…RG-8 and RG-58 have 50 Ohms. RG-59 and RG-6 (Low Loss Version of RG-59) have 75 Ohms. Most antennas and transmitters including ours are 50 ohm. Check our website for good coax. -
Page 7: Troubleshooting Table
TROUBLESHOOTING We hope you’ll never get to this step. We all know bad things happen. But do not despair! Fuse is the first thing to check. SWR and TEMP protection should help, too, although you should still be careful not to exceed ratings. Next check your mains power supply and antenna, make sure they are working properly. -
Page 8: Menu System
MENU SYSTEM: The UP and DOWN keys are used to change parameter value. In normal mode the LCD simply shows the frequency and power. Menu key can be used to enter the menu mode, repeatedly pressing this key brings up the following menus: POWER, TREBLE, BASS, COMPRESSION, THRESHOLD, ATTACK, DECAY, INTEGRATION INTERVAL, FIRMWARE VERSION, PLL STEP, LEFT CHANNEL GAIN, RIGHT CHANNEL GAIN, RF EQUILIZER, CONTRAST AND STEREO MODE. - Page 9 Setting the compression level Setting the compression threshold Setting the attack time, this is the time between the signal rise and the actual response of the compressor Setting the decay time, this is the time the compressor needs to respond to a decrease of the signal Setting the integration interval, this is the time the DSP extracts the samples Integration interval determines the energy needed to trip the compressor.

RF EQ selection FIRMWARE This option allows you to display transmitter firmware version and date. Firmware version LCD CONTRAST Select for the best visibility. Contrast is slightly affected by ambient temperature and you can adapt it to your needs here. -
