AUXILIARY HEADSET MICROPHONE OPTIONS
All RS-600 series beltpacks provide a 2.5 mm jack for connecting a Clear-Com
CC-25 headset or similiar ultra-light headset. The gain of this circuit is
optimized to match the Clear-Com CC-25 headset’s microphone.
The auxiliary headset jack may work with some cell phone-type headsets, but
problems with audio response, nulling, acoustic feedback, and noise leakage may
result.
You have the same options for the auxiliary headset microphone that you have
for the main headset microphone. Figure 4 shows the auxiliary headset
microphone options.

MAIN HEADPHONE OPTIONS
With Limiter selected, the beltpack prevents the volume in the main headphone
from exceeding a level that could cause temporary or permanent hearing damage
to the person wearing the headset.
Limiting the headphone volume is the default setting. This setting should only
be turned off, by clearing the check box, for very specific circumstances such as
increasing the headset volume for a hearing-impaired user.
