T/T Pulse Mode : Pulse to Tone Switching Key Tone Mode : Data Key # Pulse Mode : This Key will operate as a redial key if it is pressed first after off - hook. Otherwise, it will be allowed as a pause key. Tone Mode : Data key • • ST: Store If the ST key is allowed when the dialer is set to the corresponding condition, pressing the ST key will change the dialer into the ST mode. The ST mode is released after the memory transfer operation is executed. The dialing sequence will be interrupted when the key is activated. • R/L This key will be allowed location selection in store mode and will he allowed recall function in normal mode. • F: Flash (i = 1, 2, 3) If the Flash key is pressed, DP and X'MUTE will be forced to low during the tFL (Fash Time) F1 F2 F3 92mS 312mS 608mS Flash Time Selectable on the Keyboard KS58550 UNIVERSAL 10 MEMORY DIALER • RD/P KEY If press this key first after off - hook, it will operate as a redial key, otherwise it will operate as a pause key. • HFI Hands-Free dialing input. Hands-Free dialing output is controlled on the keyboard (HFl) • HDI Hold function input. Hold function is controlled on the keyboard (HDl). The output will control the melody enable.
