Headset Power Switch and Volume Control

A power switch is provided on the volume control. This control is located on the right ear
dome on the UHW headsets, and on the left ear dome on the FHW headset. Volume should
be set at a comfortably high audio level to optimize performance but not so high as to cause
audio distortion and hearing discomfort.

Operation

The base station should be installed and powered up prior to operating the headset. If the
headset has not been previously paired to the base station, refer to the “Pairing Section” for
instructions. Turn the power switch on, the green LED will flash rapidly to indicate that the
headset is attempting to link to the base. The link LED on the base station will also be flashing
rapidly at this point. After approximately 5 seconds the headset will link to the base and the
green LED will turn on steadily to indicate that the headset is linked to the base. The headset
will also sound a one time double-beep on connection to the base. Once the connection is
established, full duplex communication between the base station and the headset will become
possible.

Out-of-Range Warning

All wireless headsets incorporate an out-of-range warning to warn the user against exceeding
the coverage range of the headset. The headset will sound a 1 second cautionary beep every
10 seconds when the headset is at the fringes of the coverage range and before the headset
goes completely out of range and looses its link to the base. The cautionary beep will stop if
the user steps back into range from the base station.

Warning: Firecom recommends that the headset always be operated 
within the coverage range to ensure consistent and clear communications 
to ensure the safety of the crew and help them perform their duties in the 
safest and most effective manner.

Reconnect Feature

Should the headset go out of range and loose its link to the base station, the headset is 
capable of automatically reestablishing its link to the base within 10-15 seconds of the head-
set’s coming back into range. However, if the headset is not able to reconnect to the base
station within 5 minutes of loosing its link, the headset will be timed out and powered down
automatically. The user will then have to cycle power to the headset in order to reestablish 
the link to the base station.
