• Genera l Dialing
( or and HFI↓ ) D1 , D2 , … Dn
a.. D1 D2 , … Dn will be dialed out.
b . Dialing length is unlimited, but the re-dial is inhibited if it oversteps 32 digits
• Re-dialing
a . on hook and re-dial Off hook , D1 , D2 ,… , Dn , busy, then On hook , Off hook ( or On
hook and HFI↓ ) RD
or ( On -hook and HFI↓ ) , D1 , D2 , … , Dn , busy, then HFI↓ RD
Off -hook ( or On-hook and HFI↓ ), D1 , D2 , … Dn , busy,
RD
b . direct re-dial Off -hook or ( On -hook and HFI↓ ) , D1 , D2 , … , Dn , busy ,
on-hook R D . If the dialing from D1 to Dn is finished, press RD the pulse output pin will
become low voltage for 2 . 2 minutes , and automatically insert 6000ms for pause.. If press RD
before finish dialing from D1 to Dn , there will be no pulse output.
• “Pause” key operation
Off hook (or On-hook and HFI↓ ) D1 , D2 , P , D3 … Dn
a . pause function can be stored in memory storage.
b . pause function can be performed when general dialing or re-dial or memory dialing.
• pulse -→ tone mode convert ( * / T )
