About Cordless Terminals
A cordless terminal is a multifunctional terminal that interconnects its Bluetooth® terminal and Bluetooth® handset with each other using Bluetooth® wireless technology to maintain calls or perform other operations between them.Key Functions
- Bluetooth® Terminal: Originating and answering calls, registering Bluetooth® headsets.
- Bluetooth® Handset: LCD display for date, time, phone number; line keys for pre-programmed functions; incoming call/charging lamp; audible key touch tone; ring tone for incoming calls; volume/density control for receiver and ring tone volumes, and LCD contrast.
Talking Range
Up to 50m in line-of-sight distance. Range may be shortened by environmental factors like walls.Charging
