If You Have BizTouch 3 Feature Telephones
If you have BizTouch 3 telephones, follow these steps to upgrade their firmware. You can upgrade all phones
at the same time.
1. Unplug each phone’s line cord from the modular jack on the back of the BizTouch 3.
2. Plug the line cord back into the jack.
The BizTouch 3’s LCD display shows the status of the upgrade process.
The upgrade takes approximately ten minutes per phone and you cannot use the phone dur-
ing the upgrade process.
Installing the Multi-Tenant Card
If you have purchased the multi-tenant option, you received a multi-tenant card. This card must remain in the
Bizfon 680 in order for the multi-tenant feature to work. If you have a multi-box cluster, the multi-tenant card
goes into Unit 1.
To install the multi-tenant card:
1. Unplug the power cord from the Bizfon 680. If you have a Bizfon Cluster (more than one Bizfon 680
connected together), unplug the power cords from all of them.
2. Insert the multi-tenant card into the upgrade (Voice Vault) slot as shown in the following figure.
3. Plug in the power cord of the Bizfon 680. If you have a Bizfon Cluster, plug in the power cords of all the
Bizfon 680s at the same time. Bizfon recommends the use of a switched power supply or an
uninterruptible power supply.
