JBV-1 Docking Station and MJF-26 Adapter
The JBV-1 Docking Station has been designed for calibration and software update use.
The MJF-26 Docking Station Adapter makes signal connections to the phone. JBV-1 and
MJF-26 are used as one unit.
JBV-1 main electric functions are:
• adjustable VBATT calibration voltage, current measurement limit voltage
”VCHAR”, current measurement calibration current ”ICHAR”
• adjustable ADC calibration voltage via BTEMP and BSI signal
• BTEMP and BSI calibration resistor
• signals from FBUS to the phone via parallel jig
• control via FBUS or USB
• Flash OK/FAIL indication
In calibration mode JBV-1 is powered by external power supply 11-16V DC. In flashing
power for the phone can be taken from FPS-8 or external power supply 11-16V DC.

Rework procedure
Due to the large mechanical tolerance of the power amplifiers the following procedure is
necessary:
1 Put power amplifier into the MJS-76 re-work jig, the PA should be placed in the
best fit location, this is determined by firstly placing it in the largest location if
this is to large re-position the pa in the next size location, this should be carried
out until the best fit location is found.
