RF-Tuning Instructions (with Phoenix)
General
RF tunings should be made in the same order as shown in this section.
If baseband tunings are needed, they should be made before the RF tunings
Avoid unnecessary tuning – factory tuning values are always the most accurate ones.
Views in this document may change as the service software is developed. Please refer to
the Phoenix help files, phone model specific service manual and bulletins for help.
Service Tool Concept for RF Tunings
• All RF tunings should be carried out using in MJS-9Q (module jig), TDS-10 (RF-
probe) or RA-7 (RF-adapter)
• CPL-5 coupler can only be used for testing, NOT for tuning!
• Power to MJS-9Q or to JBV-1 should be supplied from an external DC power sup-
ply, not FPS-8 prommer
• MJS-9Q maximum input voltage is +9 V DC, nominal input for RF tunings is +6V
DC
• TDS-10 and RA7 needs MJF-7 (docking station adapter) in JBV-1 (docking sta-
tion). JBV-1 input voltage is +14 V DC
• Remember cable and jig attenuations when setting required RF levels
