Add new handsets to make your telephone more versatile (see page 49)
Your telephone can accommodate up to four cordless handsets. You can add new
handsets (model TL70008, sold separately) anytime, but each must be registered
with the telephone base before use.
The handset provided with your TL78108 is automatically registered as handset
1. Additional handsets will be assigned numbers in the order they are registered
(handset 2, handset 3, or handset 4). You can register a maximum of 4 handsets.
The TL78208 has two handsets automatically registered as handsets 1 and 2.
You can register two additional handsets, which will then be assigned numbers
3 and 4.
The TL78308 has three handsets automatically registered as handsets 1, 2 and 3.
You can register one additional handset, which will then be assigned number 4.
The TL78408 has four pre-registered handsets, so no additional handset can
be added to the system.
