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 sgnal
and at the same time, Normal Ringer sounds, if the RING sig-
nal 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.
[Charge Control Test]
1. IC751 pin *¶ (CHG-HIGH RATE terminal) outputs H → L →
H once, if IC751 pin *£ (VCHG-MON terminal) changes to H
→ L → H when the CHARGE signal is detected in the Test
Mode Idle status.

[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
0-0-# Terminate the Test mode.
B) Return test mode idle
Command
0-1-# Return to Test Mode Idle status.
C) Continuous receiving test group (Note 1)
Command
1-1-# CH1 continuous receiving status (LNA, AGC ON)
D) Continuous transmission test group (Note 1)

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.
