Test Frame JBS–8
Product code: 0770014
Service Accessories
JBS–8 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–8.
Suitable d.c. power supply regulation for JBS–8 concept is provided by
example JBS–7. Note, that the UI module (flex) is not required in this enviroment. Note also, that some of the signal values give wrong results
when RF shields are removed. Hence the phone should never be tuned
without the shields.

Service Box JBS–7
Product code: 0770015
Technical Documentation
Service box provides convenient test enviroment (regulated power supply,
M2BUS, preset battery reference voltage, external RF connection, audio
test loops, HOOK switch etc.) and mechanical interface in one box.
When AUDIO switch of JBS–7 is INT position, the AF signals are routed
normally to the modular–type system connectors. When in EXT position,
the AF signals are routed from the speaker pin of the bottom connector
straght back to the external microphone pin of the phone. Thus the
speech codec of the phone is able to feed the internally generated test
signal to the loudspeaker line, and measure the same signal from the
EXT MIC line. Whenever audio signals are to be monitored or measured
outside the phone, the AUDIO switch of the JBS–7 must be in INT position.
HOOK switch of the JBS–7 enables the audio signals to be routed to and
from the phone via the bottom connector also when the phone is in cellular mode, for example during a test call to some cellular tester. When
HOOK switch is in OFF position and the phone in cellular mode, the audios are always routed to earpiece and internal microphone.
Additionally JBS–7 has a spare battery slot, though which the battery may
be connected to external capacity meter.
Note: When tuning the maximum power, do not use more than
10 volts d.c. in the power supply input of the JBS–7.
