Thanks. But I don't think so.Look that from worldwide.bose.com
[FONT=微软雅黑]ANR power: 5.5 to 32 VDC (provided by intercom or
other external source). Fail-safe operation allows
two-way communications with loss of voltage input
or talk-through power.
Talk-through:Auser-selectable, binaural feature that
permits monitoring of the ambient sound environment.
Output is limited to 85 dBA SPL to protect user. One AA
alkaline battery provides 240 hours operational time
and is housed in the control module.[/FONT]
