Test Frame JBS–16
Product code: 0775039
JBS–16 is used when the service work must be done without covers in the
phone. The phone’s radio module is placed into plastic frame, which provides
the needed connections to the bottom– and battery connectors of the phone.
RF connection is done by RF cable, which is as well included into the JBS–16.
Suitable d.c. power supply regulation for JBS–16 concept is provided by exam-
ple JBS–7. Note, that the UI module (flexi) is not required in this environment.
Note also, that some of the signal values give wrong results when RF shields
are removed. Hence the phone should never be tuned without shields.
