Preliminary
ARD enable for ARD redial. ( connected to CPT detect circuit )
Confirm that system is in idle state.
Press ARD key.
The numbers stored in LNB redial memory will be dialing out and displayed on LCD panel. When ARD is in
operation, the SPEAKER indicator on the LCD panel will be on, and MMUTE pin will be held “ low ” to
mute microphone input.
After dialed out, speaker volume to most low level.
if the system received a busy tone, the PO pin will goes “l(fā)ow” ( line break time of ARD ) and goes “floating”
to repeat LNB redial.
if the system received a ringback tone, the system will increase the speaker volume by one step to most high
level ( for VOL1 pin and VOL2 pin control ).
if the busy tone or ringback tone is not received, this system will enter conversation mode and turn stopwatch
on.
Auto-Repeated Dialing will be interrupted by:
Pressing HF key once, or OFF HOOK action ( pick up handset ).
ARD repeat dialing time expires.
An incoming calls ( RINGDET pin from “H” to “L” level ) during ARD line break time.
ARD disable for check 32 digits LNB buffer. ( a 560K Ohm resistor connected between its CPTDET pin and
VSS )
Confirm that system is in idle state.
Press ARD key.
The phone numbers stored in memory location LNB will be dialed and displayed on LCD panel.
Checking the LNB number will be displayed on LCD panel of twice fetch.( over 16 digits ) for 2-sec interval.
The LCD display kept on for 4-sec time.
The LNB checking will be kept time, auto dial-out after off-hook ( handfree ) while the pre-dialing.
Handfree mode ( HF turn on ), press ARD .
Initiate LNB and ARD redial ( ARD enabled ) other for one key redial.
Lock Dialing and Password
When the first dialing numbers matches the previous setting numbers, the dialing function will be disabled
immediately.
Memory loss to Power on, lock 9 for initial value “ 0 ”.
Memory loss to power on, password number initial value “ ”.
Lock dialing number has 3 kinds ( 110, 119, 120 ) unable setting.
For example:
1 - - - , 1 1 - - , 1 1 0 - , 1 1 9 - , 1 2 - - and 1 2 0 - .
Lock dialing setup ( for disabled lock dialing mode )
Confirm that the system is in idle state.
Press PGM , FLASH , D1 , D2 , D3 , D4 , FLASH , Dn .
Auto-Repeated Dialing (ARD)
In idle state and CPTDET pin is “ High ”, when ARD key is pressed, the system will executes auto-repeated
dialing immediately. Operating procedures are as follows:
