Of course the BTS can be used to substitute the normal battery also during normal testing, and optionally the input d.c. may be taken from some
external power supply . However , one should take care not to exceed the voltage rating
of the phone.

Test Frame JBS–16
Product code: 0775039
Technical Documentation
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 example
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.

Service Box JBS–7
Product code: 0770015
Service Tools / Accessories
Service box provides convenient test environment (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 straight 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.
When HOOK switch is in OFF position and the phone in cellular mode, the audios are
always routed to ear–piece and internal microphone.
Additionally JBS–7 has a spare battery slot, through which the battery may be connected to external capacity meter.
