To replace the cartridge, proceed as follows:
1. Insert a No. 4 (.050 in.) hex wrench
into set screws in case (see Figure 1),
and turn clockwise (inward)
just
enough to loosen the grille-cap. Be
careful not to turn the screws all the
way into the case.
2. Remove the grille-cap, front screen,
front pad, and the two rubber washers.
3. Carefully withdraw the cartridge from
the case, and remove the side screen,
and the side pad, exposing soldered
and taped connections.
4. Remove tape from soldered connec-
tions on the bottom (not the side) of the
old cartridge and retain for use on the
new cartridge. If tape is missing or
damaged, any suitable electrical tape
may be used for step 7.
5. Carefully unsolder the three leads at-
tached to the old cartridge.
6. Carefully solder the three leads to the
new cartridge (see Figure 2).
7. Place tape over the black and white
lead solder connections of the new
cartridge.
8. Wrap the side pad and side screen
around new cartridge.
9. Insert new cartridge in case; twisting
cartridge slightly to avoid pinching
leads between cartridge and case.
10. Replace the rubber washers, front pad
and front screen, and slip grille into
place. Align holes in the grille with set-
screws in the case.
11. Insert hex wrench in set screws and
turn counterclockwise (outward) to
lock grille, being careful not to turn the
screws all the way out of the case.
