SECTION 3
TEST MODE
[Radio System Test]
• This mode is activated when
[GREETING]
key is pressed in the
Test Mode Idle status.
1.
Operation in Radio System Test mode
• In the Radio System Test mode, the RSSI is always moni-
tored at IC601
#•
pin (SIG-IN), and if RSSI is present (SIG-
IN =”Low”), the ANSWER LED turns on, or if RSSI is not
present(SIG-IN = “High”), the LED turns off.
• Current channel number is displayed on 7-SEG LED.
2.
Operation by key input
• In the Radio System Test mode, the base unit always moni-
tors the key inputs, and generates a key touch tone and goes
in the following statuses according to each key pressed.
[PAGE]
key
• Radio channel is incremented by one.
• TX ON/OFF and RX ON/OFF are same as the condition before
the channel was incremented by one.
• Channel number and 7-SEG LED display vary as follows:

[ANSWER ON/OFF]
key
• Transmit mode is turned on.
• Even in the condition other than transmit mode, key input be-
comes active to turn on the transmit mode.
[GREETING]
key
• Receive mode is turned on.
• Even in the condition other than receiver mode, key input be-
comes active to turn on the receive mode.
[TIME]
key
• Transmit & receive mode is turned off.
• Even in the condition other than transmit & receive mode, key
input becomes active to turn off the transmit & receive mode.
[SET/REC]
key
• RSSI gain is set to “Low”.
(Once the gain is set to “Low”, low gain is kept during the Test
mode.)
[MEMO]
key
• Message transmission test
• ID=AAAH and DATA=AAAH in length of frame sync + normal
message frame length are transmitted continuously until
[MEMO]
key is pressed again. When
[MEMO]
key is pressed, a message
transmission is stopped, and TX ON/OFF and RX ON/OFF are
returned to the condition before the message transmission.
[ERASE]
key
• Test Mode Idle status is resumed.
• The Radio System Test mode quits, and the Test Mode Idle sta-
tus is resumed.

BASE UNIT
[Start-up method]
1. Set the
[DIAL MODE]
switch to the P (PULSE) side.
2. Reset the POWER ON (connect the AC adapter plug) while
pressing
[TIME]
,
[REPEA T]
,
[PLA Y/ST OP]
keys.
3. Set the
[DIAL MODE]
switch to the T (TONE) side. After that
back to the P (PULSE) side.
4. Using the signal in step 3 as a trigger, the base unit reads chan-
nel information with the key matrix, and starts the Test mode.
5. After the Test mode started, the base unit generates a comple-
tion tone, then based on the read channel information, it sets
the channel and goes in Test Mode Idle status under the follow-
ing conditions:
• Relay ON (receiving status)
• 7-SEG LED “c” display
• RSSI gain HIGH
* For the DB0~DB4 logic of key matrix and channel setting, refer
to the frequency table.
[Operation in Test Mode Idle status]
In the Test Mode Idle status, the base unit always monitors the key
inputs, and generates a key touch tone and goes in the following
modes according to each key pressed.
