BASE UNIT
[Start-up]
1. Set the
[DIAL MODE]
switch to the P (PULSE) side.
2. Keeping the
[INTERCOM]
button pressed, turn the power on.
3. After a start-up acknowledge tone sounds, set the
[DIAL MODE]
switch from P (PULSE) to T (TONE) side, then return to the P
(PULSE) side.
4. Release the
[INTERCOM]
button, and the Test Mode will start.
5. Allow for normal ringer to sound at high level for duration of
500 msec after start-up, then close the line and dial Pause

6. After dialing, the base unit will go in Test Mode Idle status.
[Ring Detection Test]
1. The LINE LED blinks in synchronization with the RING sig-
nal and at the same time, Normal Ringer sounds, if the RING
signal is detected in the Test Mode Idle status.
[Charge Detection • ARTO Output Test]
1. Square-wave signal (2.4 kHz) is output to the IC751 pin
#¢
(ARTO terminal) when the CHARGE signal is detected (IC751
pin

(PARKP terminal) H
→
L) in the Test Mode Idle sta-
tus.
2. At this time, the EEPROM (IC951) is reset.

[Test Mode by Manual Input]
• The key input in the Test Mode Idle status can change the set
status to the following modes. However, the transition to an-
other mode within respective test mode groups (A-J) is possible
directly, but in case of transition to other test mode group, the
set must be returned to the Test Mode Idle status once by enter-
ing the command “0-1-#”.
A) Test mode termination
Command
Mode/Operation
0-0-#
Terminate the Test mode.
Return to Test Mode Idle status.
C) Continuous receiving test group (Note 1)
CH1 continuous receiving status (LNA, AGC ON)
D) Continuous transmission test group (Note 1)
Command
Mode/Operation
2-1-#
CH1 continuous transmission status (TX Power High)

control
Note 2:
To make a speech with the handset, first operate the set in Slave
mode by “4-4-#” command, and operate the counterpart in the
Master mode by “6-1-#” command. However, the ID must be
same. To set the same ID, perform ON-Charge in advance, or
clear the EEPROM by “7-1-#” command. In this case, however,
the speech path should be the intercom status.
G) MMI test group

• If key input sequence is correct: An acknowl-
edge tone sounds, and the set returns to the Test
Mode Idle status.
• If key input sequence is wrong: An error tone
sounds, and the set returns to the Test Mode
Idle status.

Refer to the description of “4-4-#” command.
I) Memory clear test group
Command
Mode/Operation
7-1-#
The contents of EEPROM are cleared. In case of
successful clear, an acknowledge tone sounds.
