Common Features, Communication Headsets
Auto-Leveling Microphone
The Headset automatically detects the voice of the user against noise in the background. This gives the headset an automatic VOX (noise gate or squelch) that needs no adjustment when transitioning from areas of differing noise levels.
Noise Cancelling Microphone
Noise cancelling microphones remove background noise right at the mic element.
This lets listeners hear the person talking and not the background noise.
Radio PTT
The Headset interfaces with any two-way portable radio using the wired AUX input or wireless DECT connection. When there is a wireless DECT connection, the PTT signal is passed to the wireless DECT7 Wireless Base Station and onto the Digital Intercom. Otherwise, the PTT signal is passed to the wired AUX input.
Wireless Bluetooth® Technology
Available on the APX379 headset.

Soneto’s Wireless Headsets are backwards compatible with Soneto’s first generation wireless DECT, and DECT6 Wireless Base Stations with minimal loss in functionality.
Broadcast Mode
The Headset may be paired into a listen only mode of operation, reducing power consumption considerably. This also allows many more headsets to be connected to a Wireless Base Station simultaneously. Pressing the Radio PTT button allows the headset to momentarily talk on any available slot. A tone will let the user know when they can talk. After talking, there will be a slight delay when other users cannot be heard. Refer to the Wireless Base Station manual for details.
Dual Dome Antenna Design
Each dome has a separate DECT7 antenna using diversity switching to lock onto the best signal. The user never needs to worry about head position relative to the wireless base. The best possible connection is delivered at all times.
Radio PTT or Intercom Only Selection
The Headset may be configured to send a transmit signal to radios connected via a DECT7 Wireless Base Station or Intercom. The user can transmit over multiple radios depending on the configuration.
Multi-Channel System
Depending on the wireless DECT7 Wireless Base Station or IP-DECT7 system, the user may have access to multiple channels. This allows large teams to have separate channels for different activities and enables users to change channels and become one communication team. Refer to the Wireless Base Station manual for configuration details.
Out of Range Warning
The user is notified when DECT7 signal is weak, or when it goes out of range.
Proximity Pairing
To enhance security, the Wireless Base Station will only pair to wireless DECT7 units in close proximity. This adds another layer of protection for users.
Signal Strength Reporting
The Headset may be placed into a field diagnostic mode to detect signal strength at The Headset. This can be used to optimize placement of Comus or Base Stations.
Wide Band Audio
Wireless DECT7 communications are transmitted in a high definition wide band audio format. This gives better sound quality, greater intelligibility, and improves with voice activated control systems. The Headset can also be used in narrow band if necessary.

Overall device NRR when properly fitted is: = 24dB
Notice: Improper fit of this device will reduce its effectiveness in attenuating noise (See fitting instructions).
I mportant Ear Muff Fitting Instructions:

• Inspect hearing protectors for dirt damage and foreign objects each time before you place the hearing protector / Headset on your head.
• Earmuffs offer excellent protection if the cups are fitted and adjusted properly. Your ears should be completely enclosed by the ear cups.
• Adjust the cups up or down to fit the headband securely at the crown of your head. Best performance is obtained when the cushions form a tight seal against your head. (See Fitment Section for your specific Headset type located in this User Manual)
• Never attempt to physically modify/bend/overstress the headband which may compromise NRR rating, proper fit and void product warranty.
• Test the fit as follows:

1. In a noisy environment, place the palms of your hands on both cups and push the cushions towards your head and release.
2. You should not notice a significant difference in the noise level.
3. If the noise seems to lessen when you press the cups, your earmuff is probably not fitted properly (If necessary reposition Headset and ensure hat, hair or jewelry are not interfering with proper fit/seal of the muff pad to head.

• Regularly check cushions for wear and clean them occasionally as necessary with a damp cloth or disinfect ear seal surface with non-alcohol PPE wipes. (Do not use harsh detergents or any solvents which may damage the ear seal over time). Check ear seal cushions for wear. If the cushions become hard, damaged or otherwise deteriorate, they should be replaced promptly (Contact Soneto’s or your authorized dealer for exact replacement parts.
• Warning: Hats, balaclavas, glasses or other items worn on the head may potentially prevent proper sealing and reduce the level of hearing protection significantly which can possibly cause hearing damage.

Although hearing protectors can be recommended for protection against the harmful effects of impulsive noise, the Noise Reduction Rating (NRR) is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise such as gunfire.
Cautionary Note: The level of noise entering a person’s ear, when a hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the NRR.
NRR Example:

1. The environmental noise level as measured at the ear is 92 dBA.
2. The NRR is (value on label) decibels (dB).
3. The level of noise entering the ear is approximately equal to [92 dB(A) -NRR] dB(A)].

CAUTION: For noise environments dominated by frequencies below 500 Hz “the C weighted environmental noise level should be used.’’
Warning: This communication Headset has been sealed by the factory to assure noise protection rating and lock out dust and moisture and has no internal user serviceable parts other than the batteries. Do not attempt to open or service the unit as this will potentially reduce NRR and the ability for the device to protect your hearing. Unauthorized disassembly, modification or servicing nullifies the warranty and may cause hearing loss or reduction in NRR rating if the factory seals or calibration are compromised.
