Handset Operation
F1~F4 Feature Buttons
Ringer Off Slide Switch (DKT2204-CT only)
The switch on the side of the handset turns the handset ringer On or Off (shown right). When the switch on the side of the
handset is turned to off, the Ring Off icon 
displays on the LCD and incoming calls will no longer ring on the handset. When the switch on the side of the handset is turned to on, the Ring Off icon disappears and incoming calls ring on the handset.
Note Ringing is automatically turned on again if you press Talk, function or ringer/volume buttons, receive an incoming call, or if there is no user operation for five minutes in standby mode.
F1~F4 Feature Buttons
The F1~F4 buttons on your cordless telephone can be flexibly assigned to an Extension, Line and/or Feature Access button. The F1~F4 buttons were preassigned upon system installation. Ask your System Administrator which F1~F4 button functions you have.
If you are not using these buttons for the assigned features, you can invoke the features with access codes. Please see Table 3 on page 37 for access code sequences that match your Toshiba telephone system.
For detailed feature descriptions, see the Strata CTX DKT/IPT Telephone User Guide.
