It is recommended that the following procedure be
performed on a table or other flat surface to support
the cartridge and case in order to avoid the possibility
of breaking the cartridge leads.
To replace the cartridge in the BG1.1, BG2.1, or BG3.1,
proceed as follows:
1. Unscrew and remove the grille (turning counterclockwise).
2. Gently pull out the old cartridge, being careful not to
break the leads.
3. Using a Phillips screwdriver, remove the screws which
hold the switch in place.
4. Using long-nose pliers, gently pull out the switch, being
careful not to break the leads.
5. Unsolder and remove the leads of the old cartridge
from the switch. Discard the old cartridge.
CAUTION: To prevent damage, a soldering iron be-
tween 25 and 40 watts is recommended.
6. Solder the lead closest to the RED dot on the new cartridge (see wiring diagram above) to the terminal with
the YELLOW lead on the switch.
7. Solder the other lead from the new cartridge to the terminal with the BLUE lead on the switch.
8. Using long-nose pliers, carefully replace the switch in
the case with the blank terminal on the switch facing
towards the cartridge (to ensure the UP position is
ON), being careful not to pinch the leads.
9. Placing your finger inside the case to support the
switch, secure the switch with the screws removed in
step 3.
NOTE: Do not overtighten the screws.
10. Gently insert the new cartridge into the case, being
careful not to pinch the leads, and making sure the
foam gasket on the cartridge is above the aluminum
ring.
11. Replace and screw on the grille.
