GRILLE CAP
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.
