Testing the Bells
Use the AUTO BELL TEST function to turn on all bell relays once per minute at the start
of each minute. This tests the continuity of the bell wiring circuits. This function does not
require a password.
1. If you have entered a password within the last several minutes, deactivate it by fol

lowing the instructions under Securing the Setup on page 2-9. If you do not, you will
toggle the clock between 12- and 24-hour format during this procedure.
2. Use the [6]=ENABLE CIRCUITS function to disable any relays that you do not want
to include in the test (see Enabling the Relays on page 2-4).
3. While the clock is displaying the time, press [2][3][5][5][8][7][8] to start the bell test.
While entering this code, ignore anything that displays on the screen.
Note:
After you enter the test command, there may be a delay before the bells sound.
4. When done, re-enter [2][3][5][5][8][7][8] to stop the test.
5. Use the [6]=ENABLE CIRCUITS function to re-enable any relays disabled in step 2.

If your nation does not appear in the country code list, or if the dates for daylight sav
