APPLICATION INFORMATION KEY DESCRIPTION
* 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 These are Tone/Pulse dialing signal keys in normal mode. * T/U Pulse Mode : Pulse to Tone Switching Key Tone Mode : Data Key *# Pulse Mode : No Operation Tone Mode : Data key * EM1, EM2, EM3, EM4 DIRECT REPERTORY DIALING KEY. The cascade 32 digit dialing is available and the exceed 32 digit dialing accepted one by one after all 32 digits is dialed out. In store mode, preseing EM1 ~ EM4 key will cause the 16 digits of buffer memory storing to corresponding repertory memory. * 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. * ST : Store This key will accept as store key if press it first key after off or on - hook. The store mode will be released by pressing this key again or hooking once. R/L This key will be allowed recall or location selection in indirect memory operation
