SUBSCRIPTION
The Headset and Base Unit are supplied subscribed to each other. However if you wish to
use a replacement headset with the base unit then the units must be re-subscribed as
follows:
1. Return the headset to the Headset Docking Cradle (10).
2. Use a paperclip to press and hold the Subscription Button through the access hole (18)
on the base unit for a minimum of 5 seconds. The Status Indicator (12) will then flash.
3. Press and hold the Headset Mute Switch (4) for a minimum of 5 seconds. The On-line
Indicator (5) will then illuminate.
4. Subscription completion is indicated when the Status Indicator (12) is fully illuminated
and the On-line Indicator (5) is extinguished.
5. If subscription fails within 2 minutes the headset will return to the un-subscribed state.
Solution
Unplug and re-connect the USB connector
and optional power supply
Remove and re-install the battery pack (see
Fig.5 on page 4).
Solution
Use the audio settings on the computer
or on the softphone to ensure that CS50-
USB/CS60-USB is the device used for voice.
Either the computer soundcard or the head
set you previously used for music should be
set as the audio device
Solution
Replace with a new battery pack. Refer to
the diagrams on page 4.
