Synapse Administrator's Guide
Probable Cause
The Headset is not getting
power from its battery.
The Headset and the Deskset
are not communicating with
each other.
Corrective Action
Verify that the battery is installed and charged correctly.
Place the Headset into the accessory charger. Ensure the
charger is securely plugged into an outlet not controlled
by a wall switch. The Headset LED will light to indicate
that the Headset is charging.
If the battery is completely depleted, it can take up to 10
minutes to charge the battery enough for the Headset to
work even briefly. In this case, the ON/OFF LED will
remain off and you will not be able to use the device. After
10 minutes of charging, remove the Headset from the
charger and press ON/OFF on the Headset or HEADSET
on the Deskset to turn on the Headset.
Replace the Headset battery.
Confirm that you have placed the Headset in the charger
before you press
If registration does not start, try lifting the Headset out of
the charger for a few seconds before placing it back.
