To dial a number from repertory memory (HKS
mustbe low),enter the following:
MEM (Location0-9) or E1-E3
To save the last number dialed, enter the follow-
ing:
PROG MEM (location0-9) or E1-E3
HOOKFLASH
D1
FLASH
D2
...etc
Hook flash may be entered into the dialed se-
quenceat any point by keying in the function key,
FLASH. Flash consists of a timed break of
585ms, 300ms or 100ms depending on the Mask
option. When a FLASH key is pressed, no further
key inputs will be accepted until the hookflash
function has been dialed. The key input following
a FLASH will be stored as the initial digit of the
new number, overwriting the number dialed be-
fore the FLASH, unless it is another FLASH.
FLASH key pressed immediately after hookswitch
or LND will not clear the LND buffer unless digits
are entered following the FLASH key.
Example:

PAUSE/LASTNUMBER DIALED
If the PAUSE/LND key is pressed right after off
hook or FLASH key, it is considered as LND, if it
is pressed after a digit, it will be considered as
PAUSE.
LAST NUMBERED DIALED
OFF-HOOK PAUSE/LNDor FLASH PAUSE/LND
Last number dialing is accomplished by entering
the PAUSE/LNDkey.
PAUSE
OFF-HOOK D1
PAUSE/LND
A pause may be entered into the dialed sequence
at any point by keying in the special function key,
PAUSE/LND.Pauseinsertsa 3.1seconddelayinto
thedialing sequence.The total delay,includingpre-
digit andpost-digit pausesis shownin Table 3.

Table 3:
SpecialFunctionDelays
Each delay shown below represents the time re-
quired after the special function key is depressed
until a new digit is dialed. The time is considered
”FIRST” keyif all previousinputs have been com-
pletelydialed. The time is considered”AUTO” if in
redial, or if previousdialling is still in progress.

HOLD
When HOLD key is pressedduring off hook,there
are two options. The first option is to mute the
phone (LED will blink) and the conversation can
be resumed by pressing the HOLD key again.
The second option is to mute the phone (LED will
blink), on-hook the phone (LED will still blink at
1Hz frequency) and automatic switch off the
phonewhen parallel phoneis off-hook.
The HOLD function is disabled when the line cur-
rent drops below 20mA.
SOFTSWITCHFUNCTION USING TONE/PULSE
MODE SWITCH
When dialing in Pulse mode after off-hook, switch-
ing TONE/PULSE mode switch from Pulse to Tone
will causethe device to changethe signaling mode
into tone signal and store the softswitch function in
the LND memory for redial. To redial the softswitch
function(mixed mode dialing)in thepulse mode af-
ter going on-hook and back to off-hook, you have
to switch the TONE/PULSE mode switch back to
pulsemode either beforegoingon-hookor after off-
hookor during on-hook.
Subsequentmode change from Tone to Pulse will
change the signaling mode to pulse dialing se-
quencebut this mode change will not be storedin
.the LND memory.
Whendialing in Tone mode afteroff-hook,aswitch-
ing of TONE/PULSE mode Switch from Tone to
Pulse will cause the device to change the signaling
mode into pulse mode but this mode change will
not be stored in the LND memory. When LND key
is pressed in Tone mode after going off-hook, the
devicewill outputall tone signals.
A pacifier tone of 75ms is provided after 32ms
debounce time when switching from Pulse to
Tone mode.
Redial by the LND key will repeat the mixed dial-
ing sequencein Pulsemode.
