8.5. Registering a Handset to a Base Unit
To Register an Additional Handset to a Base Unit (Easy Registration)
The included handset and base unit are preregistered. After purchasing an additional handset, register it to the base unit.
Ensure that the additional handset is switched on. If it is not on, press and hold
for few seconds to turn the handset on.
Note:
·
If an error tone sounds, or if is still flashing, register the handset manually (manual registration).
· If all registered handsets start ringing in step 2, press to stop. Start again from step 1.
· Charge the batteries of your additional handset for about 7 hours before initial use.
·
This registration method cannot be used for handsets that have already been registered to a base unit. Register the handset
manually (manual registration).
To Register a Handset to an Additional Base Unit (Manual Registration)
You can register a handset to a base unit manually using the following method.
8.5.1. Cancelling a Handset
A maximum of 6 handsets can be registered to a base unit. A handset can cancel its own registration (or the registration of
another handset) that is stored in the base unit. This will allow the base unit to “forget” the handset.
