TH688
The freedom of a GSM mobile system but with the cost
savings of a DECT cordless phone.
The TH688 allows you to take your office with you. In GSM
mode, the handset has full data and fax capabilities with an
infrared modem adapter. In either setting it offers you high
speech quality. In GSM mode it allows you to send and
receive SMS messages. And it can subscribe to no fewer
than 8 different DECT systems, making it ideal for multiple
site configurations.
Highlights:
• GSM and DECT technology in one device.
“Freedom is having the best of both worlds in one phone…
now there are no limits to what I’m capable of achieving.”
