Specifications
- Model: H9140-HT
- Product Type: Headset
- Compatibility: BTH Headsets
Product Usage Instructions
Disassembly of Headband Spring From Headset:
- Remove nut and washer stack on each ear dome using an 11/32 nut driver or socket.
- Detach the spring assembly from each ear dome during the process.
Removal of Overhead Cord From Nape Cushion:
- For Model H9140-HT and newer BTH Headsets with a slit along the D-channel:
- Peel back carefully with overhead cord until removed.
- For older BTH headsets without the D-channel slit:
- Use small blade scissors to cut a slit along the D-channel and peel back with overhead cord until removed.
Installation of Rail Adapters to Headset Ear Domes
- Check the Adapter Housing’s orientation and rotate the base as needed until the locking tab is between the Dual-Tension Spring.
- Secure the Slider Mount to the headset ear dome using provided hardware in the specified order.
Donning Instructions
- Orient each dome over user’s ears by slight rotation and adjustment of the Slider Mount.
- Press inward at the bend of the Dual-Tension Springs until each side clicks into the engaged position for use.
- For relief, grab each ear cup and pull outward until each side clicks into the disengaged position.
- Rotate ear domes towards the rear of the helmet shell when not in use.
Frequently Asked Questions (FAQ):
-
Q: How do I adjust the headset for optimal positioning?
- A: Orient each dome over your ears through slight rotation and adjust the Slider Mount back and forth over the Dual-Tension Spring until optimally positioned.
-
Q: What should I do if my headset is an older model without the D-channel slit?
- A: Use small blade scissors to carefully cut a slit along the D-channel and peel back with overhead cord until removed.
KIT, CONVERSION, BTH TO HELMET RAIL, ARC STYLE
The 22610G-01 Headset Conversion Kit is designed to convert any DCCI
traditional behind-the-head (BTH) style headset to operate as a helmet-mounted
unit on cutaway Special Ops helmets with compatible Accessory Rails (e.g.,
Ops-Core FAST helmets and Galvion Caiman helmets; consult DCCI to confirm
compatibility.) It includes a detent feature, allowing the user to either
clamp into position over the ears when communication/noise attenuation is
required, or detent outward to relieve clamping pressure when not in active
use.
Installation Instructions
Disassembly of Headband Spring From Headset
Remove nut and washer stack on each ear dome by unfastening the nut with an
11/32” nut driver or socket, detaching the spring assembly from each ear dome
in the process (see Figure 1).
Removal of Overhead Cord From Nape Cushion
- Model H9140-HT and newer BTH Headsets will have a slit along the edge of the D-channel, spanning the full length of the nape cushion. Peel back carefully with overhead cord until removed (see Figure 2).
- Older BTH headsets do not include the D-channel slit referenced above. For such models, use a small, thin blade scissors or shears, positioned with the tip of the blade inserted in the D-channel opening (between the overhead cord and channel edge) and carefully cut a slit, spanning the full length of the nape cushion, then peel back carefully with overhead cord until removed (see Figure 3).
Installation of Rail Adapters to Headset Ear Domes
- Check the Adapter Housing’s orientation, rotating the base as needed until the locking tab is in between the Dual-Tension Spring (see Figure 4).
- Using the provided hardware, secure the Slider Mount to the headset ear dome with the washers and nut in the order as shown below (see Figure 5).
Installation of Rail Adapters to Helmet Rails:
Slide the Adapter Housing into the bottom dovetail slot of the helmet
accessory rail (vertical section), ensuring full and proper insertion, with
the locking tab facing toward the front of the helmet (see Figure 3). Engage
the locking tab into one of the accessory rail slots. Make sure the overhead
cord is routed in-between the adapter spring and the users head. Plan cord
routing to avoid/minimize obstructions (e.g., snag hazards, allowances for
dome rotation, etc.) then apply hook and loop patches to fasten the overhead
cord to the helmet as desired (see Figure 6).
Donning Instructions
Orient each dome over user’s ears to the desired position through slight rotation of each ear dome, as well as adjustment of the Slider Mount back/forth over the Dual-Tension Spring, until optimally positioned over the ear.
- For use, press inward at the bend of the Dual-Tension Springs until each side “clicks” into the engaged position.
- For relief, grab each ear cup and pull outward until each side “clicks” into the disengaged position.
- Ear domes may also be rotated towards the rear of the helmet shell, away from the ears, when not in use.(see Figure 6)
Use and Care Instructions
- When not in use, helmet should be stored with headset in the engaged position, with ear domes over the ear position (not over the helmet outer shell.)
- Inspect for debris and/or salt build-up, brush away with a nylon/synthetic bristled utility brush. Clean regularly with mild soap and water, using a clean cloth.
- Regular use of appropriate corrosion inhibitors in marine environments is encouraged after thorough cleaning. Consult Series 9100 Component Maintenance Manual, doc. #19602P-99, for more
- details.
