2. GENERAL DESCRIPTION
[NF-2S]
Consisting of one Base Unit and two Sub-Units, the NF-2S Window Intercom system is designed
to relieve problems in understanding face-to-face conversations through a partition or face masks.
Since the Sub-Units’ built-in magnets allow them to be easily attached to both sides of a partition,
they can be used even in locations without ample mounting space.
[NF-CS1]
The NF-CS1 Expansion Set is designed exclusively for use with the NF-2S Window Intercom System,
and consists of a System Expansion Sub-Unit and a Distributor for sound distribution. The coverage
area for assisted conversations can be expanded by increasing the number of NF-2S Sub-Units.
3. FEATURES
