TOA EC-100M
Chime Microphone
The EC-100M microphone is equipped with an electronic chime. It can be operated as easily as normal type microphones, and can be used in any locations. The EC-100M’s power saving design permits it to be operated for approximately 2 years (on the assumption that it is used 150 times a day) on two R14P batteries. (It is highly recommended that the batteries be replaced every 2 years to avoid battery leakage.)
