JBV-1 Docking Station and MJF-7 Adapter
The JBV-1 Docking Station has been designed for calibration and software update use.
The MJF-7 Docking Station Adapter makes signal connections to the phone. JBV-1 and
MJF-7 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.
MJF-7 main electric functions are:
• phone recognizing from BTEMP
• filters of FBUS signals
• Proximity sensor calibration plate
• White light source for camera testing
• Possibility to use TDS-11 ambient light sensor calibration lamp
• Possiblity to use TDS-10 for RF tuning or CPL-5 for RF measurement

Spare parts for MJF-7
MJF-7 has a white light source integrated to the structure for Camera Testing. Light
source has limited lifetime and it starts to lose brightness as it is used. It is recommended that the light source be changed every 1000 hours of use.
Spare part code: JBS-28 Uniform Light source module 0770335

CPL-5 RF coupler
The CPL-5 RF coupler has been designed to be used with MJF-7 and JBV-1. CPL-5 allows
service technician to measure performance of NHL-2GSM RF. RF tuning with CPL-5 is
not allowed.

TDS-10 GSM RF probe for RF tuning
GSM RF probe has been developed for repair places where easy access for RF tuning s is
essential. Only Sim cover of the phone has to be removed and then phone is ready for RF
tuning. This probe has to be used together with MJF-7 and JBV-1.
Product Code
TDS-10 GSM RF probe for RF tuning 0770436

Spare pins for TDS-10
The pins which make RF connection to phone are quite sensitive for mechanical stress.
Spare pins are available with the following codes.
Ground pin, TDS-10 Accessory 0770437
Insulated antenna pin, TDS-10 Accessory 0770438
Insulated pin can be hard to insert without experience. The following tool is available to
help in this operation:

TDS-11 Calibration lamp
Ambient light sensor of NHL-2 tranceiver needs to be calibrated after certain service
operations. TDS-11 must be used together with JBV-1 and MJF-7.
Note! TDS-10 is made out of metal and it is not recommended to keep it installed when
making coupler measurement or RF tunings with TDS-11. Remove TDS-10 always from
MJF-7 when not using it. TDS-10 brightness also weakens in lond term use. Ambient
light sensor calibration system (JBV-1+MJF-7+TDS-11) must be calibrated time to time
with golden phones (Selected phones from production line) in regular intervals.
