4-1. 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/VMWI LED)
at the same time.
[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 VMWI
LED is lit. When off-hook is detected and the Branch detection
terminal IC501 Pin
(¢
(EXT_DET) detects H, the VMWI LED is
turned off.
