Lights; Ringing Tones - AT&T System 25 User Manual

Lights

Your cordless telephone uses red LEDs (light emitting diodes) to
indicate the call status for each line. These LEDs normally
remain off. They become lit only when you take some action,
such as pressing STATUS, ON/OFF, a feature button, or lifting
the handset from the base unit. The LEDs flash or blink to
indicate different call states, as described below.
A steady light indicates the line or feature in use.
A slow flashing light indicates an incoming call.
A fast blinking light indicates a call on hold. (An
intermittent blinking green light indicates a call
held temporarily while being transferred or
conference. )
