Subsets
For proper operation, the SP2 Remote Handset/Speaker Amplifier Station must be installed with a remote
subset configuration from the following list:
single or multi-party desktop subset
single or multi-party desk-edge subset
single or multi-party flush-mount subset
The SP2 Remote Subset must be mounted within 10 feet of the subset due to the subset cable limitations.
In addition, the amplifier enclosure must be mounted at an indoor location—the amplifier enclosure is not
designed for outdoor use.
