First and foremost... no installation is required!
Connect your stereo or mono headset to CellSet and plug CellSet into your intercom or radio. Then plug CellSet's cellphone cable into the headset jack on your phone*.
Use your radio/ICS system as you always do. When there's a phone call, CellSet "wakes-up", significantly amplifies the cell phone's audio and ports it to your headphones (of course, talk on the phone through your boom mic.) Even if your radio or intercom is inoperative, CellSet will still let you talk on the phone.
When the call ends, CellSet goes to sleep.
While sleeping, it draws only about 20 ľA of current, so you can expect nearly 2 years of standby time or 30 hours of talk time from a single 9 Volt transistor radio battery.
