Mn or Ln , On-hook ( or On-hook and HFI)
a . Dialing out D1 D2 Dn first, then press the storage key S
b . D1 D2 Dn numbers are stored in the position Mn or Lnand dialed out.
c . Mn = M1~ M3 Ln = 0 ~ 9 * # pause key ( P )
Off-hook ( or On-hook and HFI) , S D1 D2 , Dn S
Mn or Ln , On -hook , ( or On-hook and HFI)
a . D1, D2 Dn are stored in Mn or L n but will not be dialed out.
b . P and * / T key can be stored in the memory as one digit P key indicates pause.
c . Once the storage function is finished or the state of hook switch changes the storage mode will
be released.
Memory dialing
a . One-key dial Off-hook ( or On-hook and HFI), Mn
b . Two-key dial Off-hook ( or On-hook and HFI) A , Ln
