Page 5: General Information
Always adhere to the instructions classified with the warning signal carefully, as otherwise the MSK 25 test receiver may be damaged or even be destroyed. This symbol provides information on measuring functions and refers to chapters containing further particulars on a subject. -
Page 6: Functionality
Functionality The MSK 25 has been conceived as a portable test receiver for TV, SAT and FM radio measurements, as well as for DVB-C, DVB-S and DVB-T in both, battery operation and mains operation. The built-in lead battery (3.4 Ah) and a wall power supply with a built-in charger, suitable for 230 VAC, are included in delivery. -
