NSM-3
MODIFICATION FOR JBU-6 (SCD-6)
In some cases there have been problems with Service Box (JBU-6) while
tuning NSM-3. The problem occurs, if 1800 MHz channels and the highest
power level are used. Then it is possible that RF 'goes in' to the MBUS line of
SCD-6 module, causing several kind of malfunctions in phone (switches off
etc.).
Note: If the phone works fine during the tuning, no further actions are
needed.
To prevent above mentioned interference a shielded cable for SCD-6 module
has been taken in use. All JBU-6 Service Boxes are equipped with a new
SCD-6 modified module since production code HD1403618 (April 2000) (see
type label in the bottom of the Service Box). Also all spare part SCD-6
cables, produced in April or later, are modified.
