4-3. HANDSET TEST MODE
[Start-Up]
1. Press the TALK , 0 , and 1 keys simultaneously to start.
2. The normal ringer is rung at a high level for 500 msec after start-
ing, and the TALK LED and BATT LOW LED blink together.
The HANDSET TEST MODE and idling state LEDs will re-
main lit.
3. The unit sets into the test command key input standby state. The
state can be changed to a desired test mode item by pressing a
command key.
4. In the HANDSET TEST MODE idling state, all LEDs are turned
ON (the state where the LCD backlight lights up).
[Battery Low Detection Test]
1. In the HANDSET TEST MODE idling state, if Low Battery
is detected (if the battery input terminal (IC401 Pin
&¶
) is
grounded), the TALK (Basic) LED goes off. A confirmation beep
which lights up the BATT LOW LED sounds.
2. If the Low Battery state is cleared (if the battery input terminal
(IC401 Pin
&¶
) is released its grounding), the TALK (Basic) LED
is lit. The BATT LOW LED goes off and the previous HAND-
SET TEST MODE idling state is returned.
3. The mode cannot be changed to other HANDSET TEST MODE
with Low Battery detected (Battery input terminal (IC401 Pin
&¶
) is grounded.
[Setting the Handset Test Mode by Test Command Key
Inputs]
By entering test commands from the keypad in the HANDSET TEST
MODE, the following test items can be set.
• However, to set a test with a different test group, be sure to return
to test mode first and then set the desired mode.
A) Test Resetting

Mode/Operation
Ends the test mode. Clears the EEPROM data. Sounds
the ACK beep if OK. Exits the test mode and returns to
the normal operating state.
Returns to test mode idling.
Note:
In the continuous reception test, the “All 1’s Data” in ASIC
should be used.
