The JBV-1 and the
DA-40 are used as
one unit.
In the calibration
mode the JBV-1 is
powered by an
external power supply: 11-16V DC.
When flashing, the
power for the phone
can be taken from
the FPS-8 or an
external power supply: 11-16 V DC..
Note! The JBV-1 main electrical functions include the following:
•Adjustable VBATT calibration voltage, current measurement limit voltage:
VCHAR, current measurement: ICHAR
•Adjustable ADC calibration voltage via BTEMP and the BSI signal
•BTEMP and BSI calibration resistor
•Signal from FBUS to the phone via the parallel jig

repair jig is designed
for regional service
centers to allow
component level
troubleshooting,
testing and analysis.
Note! The supply
voltage for the MJ34 has to be kept
within the range 812V when using the
build in the regulator.
When bypassing the
regulator (IMEI
rewrite) the voltage
must be kept below
5,4V.

Operating instructions:
When inserting the PWB be careful to place it over the steering pins.
When inserting the UI flex, use the enclosed tweezers (placed on the left side of the jig, se e
pic above) to avoid damaging the flex. Be very careful when handling the UI flex, as it is very
fragile and easily breaks!
See this picture:
The display flex can be mounted carefully by hand. When removing the display flex, use the
special tool (placed on the right side of the jig) to carefully twist up the connector.
See this picture:
The switch marked “ON-OFF” has the same function as the reset switch in the SIM reader .
When in off position, the battery voltag e is switched off. This is used to test the reset circuit.
RJ-38Soldering Jig0780381The RJ-38 soldering
jig is used for soldering and rework for
the main board. the
material is resistant
to the heat used by
lead free soldering.
