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”, cur-
rent 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
Product Code
JBV-1 Docking Station: 0770298
MJF-7 Docking Station Adapter: 0775285

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 recom-
mended 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.

RA7 RF adapter
RA7 RF adater is low cost option for NHL-2 RF tuning. RA7 can be used together with
FLA-21 or MJF-7/JBV-1 combination. Four screws has to be opened in NHL-2 Transceiver
and Acoustic chamber has to be removed in order to be able to use RA7 RF adapter.
