The Shure RPM210 is a replacement screen and grille assembly
for Model SM57 and 545 and UNIDYNE

)

III-type microphones. The
RPM210 consists of the complete screen and grille assembly, an
extra retainer ring, and separate SM57 and 545 nameplates. If you
have a Shure microphone that requires a different nameplate
(SM77, PE65, PE66, etc.), please contact Shure's Service Depart­ment.

IMPORTANT: The RPM210 replacement procedure should only

be performed by qualified service personnel.

REMOVAL

CAUTION: Use extreme care in removing the screen and grille

assembly. Avoid damaging the clear plastic diaphragm! Bending or
tearing the diaphragm will affect the microphone response, and
may require complete cartridge replacement.

1. Peel the old nameplate off and discard it.

2. Rotate the grille assembly until the two metal tabs are cen-

tered above one of the recessed flat areas (visible through the
perforated collar). Refer to the exploded diagram above.

3. Use a small (1/16 in. blade maximum) screwdriver to depress

the two metal tabs while you lift the grille up and over the metal
tabs.

INSTALLATION

CAUTION: As in the disassembly process above, take care not

to damage the clear plastic diaphragm!

1. Remove the retainer ring from the new screen and grille
assembly.

2. Wrap the new retainer ring around the cartridge groove just
above the perforated collar.

3. Hold the two ends of the retainer ring closed around the car­tridge and center them above a flat area on the side of the car­tridge.

4. Hook the crimped tab at the back of the retainer ring into one
of the two slots in the grille.

5. Lower the front edge of the grille assembly over the retainer
ring until it contacts the tops of the two metal tabs and holds
the retainer ring closed. Be sure the collar is tucked under-

neath the grille.

6. Use a small screwdriver to tuck the two metal tabs under the
edge of the grille assembly. Continue lowering the grille
assembly into place until the tabs lock into the slot on the
retainer ring.

7. When properly assembled, the grille assembly can be rotated
while the perforated collar is held in one position.

8. Remove the paper backing from the replacement nameplate.
Locate the raised index mark along the lower edge of the grill
assembly and affix the nameplate so that it covers the retainer
ring holes, but not the index mark.
