Subscribing a CS50 Replacement Headset or a CS55 Replacement Headset

First, you want to make sure you have the correct headset, since the CS50 Replacement Headset and the CS55 replacement headset for the wireless systems look identical but work on different frequencies, so they’re NOT interchangeable.  You can find the system model number on a label under the base.  The CS50 Replacement Headset is part #64402-14; CS55 replacement headset is part #72195-03 (see links below).  Confirm the correct headset with your invoice.  If you have the wrong headset, contact your retailer to do the exchange.  If everything is correct, let’s get started.

The first thing is to start with a fully-charged headset.  If you’re needing to re-subscribe a headset, remove and re-install the battery of the headset (leave it disconnected for about 15 seconds).  The battery is located in the headset under the grey cover with ribs on the sides.  Be careful when removing the cover as it has two small fragile locking tabs.  Doing this resets (clears) the headset and prepares it for subscribing.  If you’re working with a new headset, these steps are not necessary.  Now carefully follow the subscription instructions below.

OLYMPUS DIGITAL CAMERA5) The last step is to unplug the AC power adapter for 5 seconds, then reconnect.  You can unplug the cord either from under the wireless headset base or from the wall.
