Elvex Guide System is a communications ear muffs set consisting of transceiver and receiver
units, and a hand held microphone. All headsets are hearing protectors with an independently
verified 22 dB NRR (Noise Reduction Rating). The transceiver can transmit and receive, while
the receiver can only receive. The transmission range is up to 25 meters (77 feet) in ideal
conditions, when no barriers or obstacles interfere with transmission.
Potential applications:
•
Guided tours in noisy environments: A person can guide a group of individuals through a
plant, explaining a process or technology.
•
A group participant can use the Guide Microphone to ask the guide a question.
•
Two individuals may communicate in a noisy environment by using two transceivers.
Controls, Transceiver and Receiver:
•
The receiving channel selector has three available channels. Select the same channel # for
transmitting on the transceiver and for receiving on the receiver headsets. Select another
channel (for both) only if you experience interference.
•
The receiving channels are selected with the large circular button. The transmitting channel is
selected with the button next to the battery compartment.
•
The on/off/volume control activates and deactivates the headset and also adjusts the volume.
•
The AMP button allows the user to increase the sound level of the receiver by 15 dB. This
makes it possible to use the headset in environments with noise levels up to 105-110 db.
Warning: when amplification is used the headset is no longer a hearing protector. The headset
still provides 22 dB NRR, but the sound level inside the headset it too loud to provide
effective hearing protection.
•
The microphone is noise canceling and voice activated and mounted on a flexible stalk.
Adjust the microphone so that is sits very close to your mouth in order to have the best
performance.
