Designed for Usability
Voice clarity is a critical requirement for any help phone but in especially for handsfree help phones. KNEM-21 implements advanced acoustic echo cancellation and noise re, duction technologies allowing clear communication in the noisiest environments.The KNEM-21 audio amplifier is capable of producing up to 15 watts of undistorted digital power which is delivered to an high efficiency full range speaker.
Designed for Reliability
KNEM-21 has been designed from the ground up with reliability in mind. Extensive use of wide temperature and over-rated components helps ensure it is always operational when needed.The electronics are housed in an enclosure that is dust proof and capable of preventing entry of strong jets of water. Of course, jets of water will never reach the electronics module as the body has also been designed to prevent entry of water. All connectors used on the electronics enclosure are at least IP66 rated on both the plug and socket side. KNEM-21 can be equipped with a wide range of backup batteries (from 2.3Ah to 20Ah) allowing reliable operation through the dark months of the year when little sunlight is available for charging.
Designed for Safety
The KNEM-21 body is manufactured using SUS or CRS which allows the strength to withstand abuse by vandals, stones from cars or hail, but also ensures the phone will not significantly damage a vehicle if a collision occurs. KNEM-21 incorporates an unique internal structure that ensures all parts of the phone will be pulled down and under a colliding vehicle rather than breaking apart and possibly impacting the vehicles windscreen.
Designed for Peace of Mind
Integrated monitoring and diagnostics will alert you via SMS of abnormal phone conditions including: low battery, abnormal temperature, door tampering or solar panel removal, or if the phone is no longer standing vertical. Periodic self testing also checks the audio path (microphone and speaker). Ad-hoc self testing can be requested via SMS. Contact sales manager for details to confirm.
