4. Insert the base unit into the foot (7) and turn until secure.
5. If your telephone has volume control, set the volume to the
middle setting.
6. Place the headset into the base unit for battery charging.
Battery charging and assembly verifi cation
Initial battery charging
The battery in the headset is not initially charged and will require a
minimum of 20 minutes of charging before use. It takes 1.5 hours
before the battery is fully charged, providing up to 8 hours of talk
time.

remove the headset from the base unit and place it in the base again.
If battery charge is too low, a beep will be heard in the headset every 20 seconds.
Note: The battery charging indicator (1d) on the base unit will fl ash continuously during
charging and be lit when the battery is fully charged.
Assembly verifi cation
Verify that the assembling of the product has been completed correctly. After removing the headset from the base unit, the green
link-up indicator (1b) on the front of the base unit will light and the
on-line indicator on the headset will fl ash.
If the green link-up indicator does not light, check the wiring connections on the base unit and ensure that the power adapter is connected. If the on-line indicator on the headset does not fl ash continuously, replace the headset in the base unit and remove it again.
