registration. The light will flash quickly in
red and blue. It will take about 60 seconds to
complete the registration process.
6. The light will turn red when the headset is
registered but not fully charged, or turns blue
when it is registered and fully charged.
7. To check that registration has been successful,
press the button on the headset and check for
a dial tone. If registration has failed, you will hear,
“Not registered”, and the light on the headset
will flash slowly in red and blue.
To reset the headset, remove it from the headset
base and try the registration process again.
De-registering headsets
You may need to de-register your headsets if
you wish to register your headset to a different
headset base. Or, if you have two registered
headsets and need to replace one of them. You
must first de-register both headsets, and then
register each headset you wish to use again, one
at a time.
