( tone ) ( tone )
c . If the tone mode remains since the number is dialed out, pulse mode can be recovered as long as do
on-hook operation.
• FLASH
Off-hook ( or On-hook and HFI↓ ),
F
a . “flash” key can not be stored in the memory , but it enjoys the most high priority in all keyboard
functions.
b . after pressing “ flash” key dialer will recover to the original status.
• Number Storage
Off-hook ( or On-hook and HFI↓ ), D1 , D2 , …
Dn , S , S
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 Ln”and 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
