Measure the DC voltage at the upper solder pad o C4
(which is connected to T3 and R4). It should be
somewhere between 0.5 V and 1.0 V. I it is not, check
all solder joints or proper contact and check that all
components have been itted in the right places.
I everything is OK, the inal three
components can now be itted:
8. D1 (BAT54; marking WV4)
9. C2 & C4 (10 µF; no marking, large
SMD)
Now remove PCB 3 rom the panel, taking care to avoid damage to the tabs.
Then solder the Cinch panel-mount connector onto the PCB
( irst straighten the two ground tabs).
Remove PCB 5 rom the panel and lay PCB 3
on the bench with the Cinch connector acing
away rom you. Place PCB 5 in the proper
position on PCB 3 and perpendicular to PCB 3,
with the marking M2×6 acing the Cinch
connector. For now, solder only the pad at the bottom right.
Remove PCB 6 rom the panel and it it perpendicular to PCB 3
with the marking M2×6 acing you. For now, solder only the pad at
the bottom right.
Remove PCB 7 rom the panel and it it perpendicular to PCB 3.
The proper orientation is clearly indicated by the solder pads.
Solder all three pads.
Take PCB 4 (with the headset connector) and insert it care ully into
the rear piece and down onto the bottom piece, so that the tabs o
PCB 5 and PCB 6 it into the recesses in the side pieces. Press the
PCBs irmly together and solder them in place, starting at the
middle. While doing this, regularly check that the PCBs it closely
together at the bottom – at this point it’s still possible to make
corrections.
Now solder the joints between PCBs 3, 4 and 5 and between
PCBs 3, 4 and 6. Be sure to solder the joint between PCBs 3 and 4
at the bottom near the headset connector. I the tip o your
