Notes: For Step 37, when the HOLD key is pressed after completion of Step 36, the volume
adjustment test (that is, after alerting tones have been silenced), the LCD indicator for keys 2, 3,
and 4 will flash for approximately two to four seconds. This indicates that a circuit test is running.
No keys should be operated during that time as this may cause the test to fail. When the circuit
test is completed, LCD indicators 1 - 10 will turn ON steady and, in most instances, 10/10 will be
displayed in the display window, as detailed in Step 37. The numbers in the display, when read
from left to right, indicate a count of the messages received against the messages sent. The
numbers depend on the office parameter table and may vary between 10 and 50; however, the
number to the left of the slash should always equal the number to the right of the slash. If the
indications are as described above, the test has passed. Should one or several add-on units be
connected to the set being tested, no indications of any kind will occur on the add-on unit or units
during the circuit test. A test failure is indicated when the following occurs:
(a) the two numbers in the display are not equal
(b) only the LCD indicators for keys 1, 2, and 8 are ON
(c) LCD indicators for keys 1, 2, and 8 wink
Winking LCD indicators for keys 1, 2, and 8 indicate that the test did not run, possibly due to a
timeout in the peripherals (example: high test volume). In this case, press the HOLD key again
(Step 37) and repeat the station ringer test.
