BASE UNIT TEST MODE A
Manual System Test Mode
[Start-up]
1. Set the DIAL MODE switch to P (PULSE), and turn on the
power while pressing the HANDSET LOCATOR key.
2. Change the DIAL MODE switch from P (PULSE) to T
(TONE)
b
P (PULSE), and release the HANDSET LOCATOR
key to start up.
3. After starting up Test Mode A, perform dial test.
4. The TEST MODE A state will be set after the dial test.
5. In test mode idling A, pressing the HANDSET LOCATOR key
with the P (PULSE)/T (TONE) switch set to P (PULSE) state
switches to BASE UNIT TEST MODE A-1.
4-1-1. BASE UNIT Test Mode A-1
1. In test mode idling A and the P (PULSE)/ T (TONE) switch set
to the P (PULSE) state, pressing the HANDSET LOCATOR
key changes the mode as shown below.
2. Setting the P (PULSE)/ T (TONE) switch from P (PULSE) to T
(TONE) in the BASE UNIT test mode A-1 in any time also en-
ables the mode to be changed to the BASE UNIT test mode
idling A.
• This mode is intended for checking that the IC501 line is operat-
ing properly. Add the LINEIN signal and check that the signal is
output to the SPEAKER OUT.

[Dial Test]
After starting BASE UNIT TEST Mode A, close the circuit for about
500 msec after start, and dial PAUSE , 0 (DP), wait 2 seconds, 1
(Tone), 4 (Tone), 8 (Tone), # (Tone) in this order.
[Ring Detect Test]
1. Rings the Normal Ringer synchronized with an external call com-
ing in, and blinks the IC501 Pin
!™
,
!£
(New Call LED/MES-
SAGE LED) at the same time.
[CID Type 1 Reception Test]
1. When an external call comes in, receive the CID Type 1 signal
(the CID signal timing conforms to the regular specifications).
If it could be received correctly (determined by whether the
checksum is correct), the New Call LED is blinked, and hereaf-
ter the ringer sounds and lights up the memory match tone.
[Visual Message Waiting Indicator Test]
1. During test mode idling, receive the signal (the CID signal tim-
ing conforms to the regular specifications) of the Visual Mes-
sage Waiting Indicator generated by the PJK signal. If it could
be received correctly, (determined by whether the checksum is
correct), the New Call LED is lit. At the same time, the MES-
SAGE LED is synchronized and blinked.
[Charge Detection and ART0 Output Test]
1. Detects that the charge detection terminal IC501 Pin
@∞
(PARKP)
has turned from H to L, and outputs a square waveform signal
(2.4 kbps) from the ART0 terminal.
2. Clears the EEPROM contents at the same time.
[Charge Control Test]
1. When the IC501 Pin
!•
input (BATT_CHK) changes from
L, H, to L during charge detection, the IC501 Pin
!¶
output
(CHRG_CTL) will output L, H, LH, L, to H only once.
[Branch Detection Test]
When the shared phone is detected to be off the hook and the Branch
detection terminal IC501 Pin
(¢
(EXT_DET) detects L, the MES-
SAGE LED is lit. When off-hook is detected and the Branch detec-
tion terminal IC501 Pin
(¢
(EXT_DET) detects H, the MESSAGE
LED is turned off.
