Product code: 0770009
Dummy battery is convenient device when the battery reference voltage is to
be programmed. JBS–7 has a voltage setting for supplying specified reference
voltage needed for this programming. Of course the BTS can be used to sub-
stitute 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.
