to accommodate an electrical conduit if needed. (The unit is delivered with

one of these knockouts removed; the other can be removed if desired.)

arrow on the housing rim.

(See “Removing and replacing the receiver dome,” below.)

Reoving and replacing the receiver dome

After having installed and used the VoiceLift microphone for some period of time,

you may want to make changes to the receiver’s connections (such as adding a

secondary receiver or an auxiliary input device) or to the DIP switch settings. To

make these changes, you must detach the dome from the housing to access the base

plate. Follow these steps to remove, reconﬁgure, and reattach the receiver dome:

1. Pull any new cables to the receiver’s location that will be connected to the

receiver.

2. Grasp the receiver dome ﬁrmly and turn it counterclockwise until it stops.

3. Pull the dome away from the housing, being careful not to disconnect any of

the connectors.

4. Make any desired changes to the connections or DIP switch settings on the

receiver base panel.

5. Place the dome onto the housing,

aligning the etched arrow on the

dome tab with the raised arrow on

the rim of the housing.

6. Turn the dome clockwise until the

arrow on the tab aligns with the

raised dot on the housing rim, and

the dome snaps into place.
