Service Tool Concept for RF Tuning Operations
• All RF tuning operations must be carried out in the MJS-49 Module Jig!
• JBV-1 Docking station with MJF-27 Docking Station Adapter must not be
used for RF tunings, only for testing!
• Power to MJS-49 must be supplied from an external DC power supply, not
FPS-8 prommer
• MJS-49 input voltages:
Maximum + 12V
Nominal input for RF tunings is +4.2 V DC
Minimum +3V DC
• Remember the cable attenuation when setting required RF levels
