Diagnostic Test #2 - Signal Quality
The purpose of Diagnostic #2 is to check the voltage
level of the batteries on a battery-powered clock.
Diagnostic #2 may be enabled by pressing the MECH SW
button twice. If the clock is performing this diagnostic,
then a green LED on the back will flash twice every
three seconds. The output of the test is displayed by the
second hand.
Some examples.

Second hand is on 5, the battery level is 2.5V
Second hand is on 9, the battery level is 2.9V

Diagnostic #3 may be enabled by pressing the MECH SW button three times. If the SAW clock is
performing this diagnostic, then a green LED on the back will flash three times with a one second break
between each flash. The LED will continue to flash green until the diagnostic is complete. The clock will
confirm that the diagnostic is complete when the LED shines a different color.
If the LED is flashing red:
If the LED is a solid green, the test was completed successfully.
