CHARGING & INSTALLATIONS

Wall Adapter Charging

Only charge the Headset using the supplied 12VDC regulated wall adapter. Using unregulated wall adapters will damage the Headset charging circuit and components and void the warranty.

Vehicle Charging

Note: Make fuse no further than 18" from the battery.

Note: Only replace fuse with the same type, 1.5A AGU.

1. The unterminated end of the supplied charging cable assembly and fuse assembly must be wired to the vehicle per the diagram above.
2. Observe correct polarity when connecting the charger cable to 12V from the vehicle. Connect the RED wire to +12V and the BLACK wire to battery chassis ground. This will result in a positive center terminal of the charger jack as shown in the illustration.
   
3. Charge Headset completely before use with vehicle power 12V supply or supplied wall mount charger.
4. For maximum battery shelf life, turn OFF the Headset.

SPECIFICATIONS

Noise Reduction
This Firecom Headset provides 24dB noise attenuation when properly fitted. Any modification to the Headset will reduce the Headset performance and hearing damage could occur. Always wear hearing protector in areas that have been identified as high noise locations.

Federal law requires the following statements:
"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."
"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."

Example

1. The environmental noise level as measured at the ear is 92dBA.
2. The NRR is 24dB.
3. The level of noise entering the ear is approximately equal to 92dBA – NRR or 68dB.
   "For noise environments dominated by frequencies below 500 Hz, the C- weighted environmental noise level should be used."
