SECTION 3
TEST MODE
[GENERAL]
The test mode of this set consists of six test items including BATT
test, LCD test, KEY test, LEARN test, MEMORY test, and
MEMORY ERASE test and further each test item comprises several check items.
[Setting/Releasing Test Mode]
Setting the test mode:
Push the [SET] key while pushing the [MENU z] key. The “BATT
TEST” will be displayed, when the test mode is set.
Releasing the test mode:
If the specified key is not pushed for more than 60 seconds while
the set is waiting for key input for the test item selection, or if the
test item “EXIT TEST” is selected.
[Test Item Selection]
1. Operation key
In the test mode, operate the jog dial and [SET] key.
2. Operating method
(1) Progress operation
Pushing the jog, progress the check items in order.
(2) Next test operation
• Clicking the left jog button at the check item selection causes
the “NEXT TEST” to be displayed for confirmation. (“NEXT
TEST” is displayed on LCD with “NEXT” blinking)
• Pushing the jog with the “NEXT TEST” on LCD causes the
next test item of current test to be displayed for selection.
• Clicking the right jog button with the “NEXT TEST” on LCD
causes the set to return to the check item before the “NEXT
TEST” display.
• Clicking the left jog button with the “NEXT TEST” on LCD is
ignored.
(3) Skip operation
• Clicking the right jog button while the set is waiting for key
input causes the “SKIP” to be displayed for confirmation.
(“SKIP” is blinking on the LCD)
• Pushing the jog with the “SKIP” on LCD allows the set to proceed to the next check item of current item.
• Clicking the right jog button with the “SKIP” on LCD causes
the set to return to the check item before the “SKIP” display.
• Clicking the left jog button with the “SKIP” on LCD is ignored.
The skip operation at the last check item for each item causes
the next test item to be displayed for selection.

3. Test item selection display list
• Test items
(1) BATT test selection display: “BATT TEST” is displayed (with
“BATT” blinking)
(2) LCD test selection display: “LCD TEST” is displayed (with
“LCD” blinking)
(3) KEY test selection display: “KEY TEST” is displayed (with
“KEY” blinking)
(4) LEARN test selection display: “LEARN TEST” is displayed
(with “LEARN” blinking)
(5) MEMORY test selection display: “MEMORY TEST” is displayed (with “MEMORY” blinking)
(6) MEMORY ERASE test selection display: “DEL MEMORY”
is displayed (with “DEL” blinking)
(7) EXIT test selection display: “EXIT TEST” is displayed (with
“EXIT” blinking)
• (1) is displayed immediately after the test mode is set.
Each time the right jog button is clicked, the display varies in
order of (1) → (2) → (3) → (4) → (5) → (6) → (7) → (1) → and
so on. Also, the display varies in the reverse direction when the
left jog button is clicked.
• Pushing the jog at any display causes the displayed test mode to
be activated.
• The test item selection screen will appear, if any test item finished, or the test mode was released in the next test. At this
time, the LCD will display the next test item of currently selected test item. However, any test item can be selected there
through the jog operation.
[Test Mode Items]
1. BATT test
(1) Battery voltage check:
Whether the battery voltage is below or over 2.5 V is checked.
“BATT CHECK LOW” is displayed if the battery voltage is below
2.5 V, or “BATT CHECK GOOD” is displayed if over 2.5 V The
battery voltage is checked at 0.5 second interval until the jog is
pushed, and LCD display is updated. Proceed to (2) if the jog is
pushed
(2) DC/DC stop check:
DC/DC is stopped whichever the battery voltage is below or over
2.5 V The set waits for either key input or jog operation. When
either the key or jog is operated, DC/DC starts, and after LCD
initial setting, the BATT test is conducted, and then the “LCD
TEST” is displayed for selection.

(4) Others
If no key is pushed for more than 60 seconds while the set is waiting for the check item selection of current test item, the next test
item is displayed.

5. MEMORY test
• For the EEPROM, the memory occupation display, writing error history display, error test, and data erasing are carried out.
• For the writing error history display, whether the data writing
error occurred since the EEPROM was erased last is displayed.
• For the error test, the data are written to all areas, and then
whether all data are correct is checked and the result is displayed.
• After the error test finished, the data in all areas of EEPROM
are erased and all settings are initialized.
(1) EEPROM memory occupation display
How many percents of all memory areas are occupied with the
learned data is displayed in steps of 10%. When no data is stored,
0% is displayed, or otherwise, the unit place is rounded up. The
set proceeds to (2) when the jog is pushed.

(g) Memory check result display
“TEST GOOD MEMORY” is displayed on the LCD if
the error flag is not present, or “TEST ERROR
MEMORY” is displayed if the error flag is present. Push
the jog, and the MEMORY test finishes and the
“MEMORY ERASE” is displayed for selection.

(1) Memory erasing
(a) Memory erasing confirmation display
“DELETE MEMORY” and “push SETkey MEMORY”
are alternately displayed on the LCD every second. The
set proceeds to (b) if the SET key is pushed.

(2) EEPROM writing error history display
In actual, each time the writing error occurred in the EEPROM,
the error flag turns on. “MISSED MEMORY” is displayed on the
LCD if the error flag is present, or “NO MISSED MEMORY” is
displayed if not present. The set proceeds to (3) when the jog is
pushed.
(3)

EEPROM error test
(a) Memory writing confirmation display
“WRITE MEMORY” and “push SETkey MEMORY”
are alternately displayed on the LCD every second. The
set proceeds to (b) if the SET key is pushed.
(b) Memory data writing (-1)
The lower 8-bit values of the memory addresses are
written to all areas.
If an error occurred during data writing, the set goes to
(g) with the error flag turned on, or if no error occurs,
the set proceeds to (c).
(c) Memory data check (-1)
All bytes are read for checking.
If an error occurred during data check, the set goes to
(g) with the error flag turned on, or if no error occurs,
the set proceeds to (d).
(d) Memory data writing (-2)
The inverted lower 8-bit values of the memory addresses
are written to all areas.
If an error occurred during data writing, the set goes to
(g) with the error flag turned on, or if no error occurs,
the set proceeds to (e).
(e) Memory data check (-2)
All bytes are read for checking. If an error occurred during data check, the set goes to (g) with the error flag
turned on, or if no error occurs, the set proceeds to (f).
(f) Memory erasing
All bytes are erased to return all settings to initial state.
If an error occurred, the set goes to (g) with the error
flag turned on, or if no error occurs, the set proceeds to
(g).
For the LCD display of (b) to (f), see below.

• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tolerances.

– 32 –

• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tolerances.
• Circled numbers refer to waveforms.
