Adding and registering handsets

Before using a new E598-2 handset, you must register it with your E5901/E5902B/E5903B/E5911/E5912B/E5913B/E5914B/ E5921/E5922B/E5923B/E5924B/E6001/E6002B/E6012B/E6013B/ E3813B or E6014B telephone base (purchased separately). The E5901/E5902B/E5903B/E5911/E5912B/E5913B/E5914B/E5921/ E5922B/E5923B/E5924B/E6001/E6002B/E6012B/E6013B/E3813B or E6014B can accommodate up to four cordless handsets.

The handset provided with the E5901/E5911/E5921 or E6001 is automatically registered as handset 1. Additional handsets will be assigned numbers in the order they are registered (handset 2, handset 3 and handset 4). You can register a maximum of four handsets.

The E5902B/E5912B/E5922B/E6002B or E6012B has two hand- sets automatically registered as handset 1 and 2. You can register two additional handsets, which will be assigned numbers 3 and 4.

The E5903B/E5913B/E5923B/E3813B or E6013B has three handsets automatically registered as handsets 1, 2 and 3. You can register one additional handset, which will be assigned number 4.

The E5904B/E5914/E5924B/E6014B has four pre-registered handsets, so you cannot register any additional handsets to it.
