How the Guide System Works

The Guide offers 2-Way communication solution tool that can be adapted and utilized in many work applications. An example would be conducting a plant/factory tour in which a individual can lead a group through the plant/factory explaining the technology or process.

There are many ways that the Guide can assist and increase work productivity such as utility work to construction and manufacturing to training. The possibilities on the Guide usage is endless and it’s easy to use!

How it Works:

Controls, Transceiver/Receiver

  • There are 3 available channels. Select the same channel number for transmitting on the transceiver and for receiving on the receiver headset. Select another channel only if you experience interference.

  • The transceiver can transmit and receive, while the receiver can only receive.

  • 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.

  • Ideal for high and medium frequency noise

  • The microphone is noise canceling and voice activated and mounted on a flexible stalk. Adjust the microphone so that it sits very close to your mouth in order to have the best performance.

Battery Life & Replacement:

  • When the transceiver is in constant transmission mode, the batteries last approximately 4 hours When transmission is made occasionally, the battery life is extended significantly and may exceed 10 hours of operation.

  • A LED light will begin to flash when the batteries have about 20 minutes of life remaining.

Handheld Microphone

  • The handheld microphone can transmit to both the transceiver and the receiver headsets.

  • The microphone can be used in a guide application, providing an avenue for visitors (using receivers) to ask questions of the guide (using a transceiver).
