The JBV-1 Docking Station has been designed for calibration and
software update use. The MJF-6 Docking Station Adapter makes signal
connections to the phone. JBV-1 and MJF-6 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.

*Note: The nominal supply voltage for MJS-46 is +8.0 V.
The supply voltage must not exceed +12.0 V (min 5V).
(MJS-46 has overvoltage protection).
For flashing with FPS-8, it is possible to bypass the regulator
(jumper).
