They are designed to meet various dialing specifications through resistor option matrix. The HT9320 series are offered in six different versions. The different functions of the six versions are listed in the selection table. The HT9320A, HT9320H versions provide the on-hook store function; the HT9320B ver- sion provides the LCD interface function; the HT9320K version provides the keytone function; the HT9320L ver- sion provides both the LCD interface function and IDD lock function. The six versions also supply the hold-line and hand-free functions, which are suitable for feature phone applications. HT9320 series provide SA, Redial and 20 one-touch/two-touch memory dialing. If the keyboard in- cludes M1~M20 keys it can be used as one-touch mem- ory dialing. Otherwise, it works as two-touch (PAGE ®M1~M10) or three-touch(A®PAGE®0~9) memory dialing for speed dialing in either pulse or tone mode.
