CTPhone 1900 System Overview
Handset icons used with the CTPhone 1900 system are shown below.
Internal Antenna
The CTPhone handset features an internal antenna which is not subject to
physical damage because it is not extracted or retracted during phone use.
Security
The CTPhone handset encrypts voice information before transmitting it.
Encryption ensures that conversations are private and inaccessible to
electronic eavesdropping.
Configurable Ringing
Users can set ring type and volume on their handset. Eight ring types,
three volumes, and no ring are available.
Ringer Mute
The handset ringer can be muted.
Key Press Feedback
The CTPhone handset can be configured to beep when any key is
pressed.
Keypad Lock
The handset keypad can be locked to prevent accidental pressing of keys.
A locked handset does not respond to any key except the power or
“unlock” keys, but releases the keypad when you receive an incoming call
and relocks it again when the call terminates.
