INSTALLATION INSTRUCTIONS
CC-95/CC-260
The CC-95 and CC-260 intercom headsets can be used with Matrix stations and Party Line
stations and beltpacks. They require minimum care and are designed to provide years of
trouble-free use. The following steps will help ensure long-lasting, proper operation.
1. Switch the station’s microphone or talk switch off and turn down the listen level before
plugging in the headset.
Note: This is a good practice before plugging
or unplugging any headset to a beltpack or
station.
2. Adjust the boom, but do not force it
past the 11 and 1 o’clock stop points.
3. Place the ear socks over the earpads
for a more comfortable fit, especially
during extended periods of use.
4. If necessary, adjust the station or
beltpack sidetone and/or listen level.
5. After putting on the headset, position
the microphone using the flexible
section of the boom. For best results,
the microphone should be no more
than three-fingers width away from
your mouth.
Note: The use of headset extension cables
is not recommended with Party Line
products because of crosstalk and sidetone considerations.
