EXTENDING
ADDITIONAL HANDSETS
Adding additional handset to the system allows all users to make full use of the call transfer and
intercom facilities. A maximum of one external call and one internal call can process at the same time.
If an additional handset is added to the system, the batteries must be charged for 15 hours without
interruption. The registration procedure must be performed prior to use. The registration gives each
handset a specific identity number 1 to 7. This number is used for internal calls only. From new, the
handset is already registered to the base unit and has been allocated number 1.
