Thus, potential problems can be detected early and trouble can be avoided. 6.1.1 Daily check Without printer paper, you cannot obtain necessary information. Therefore, check the remaining quantity of printer paper as follows: (1) Open the paper cover on the front panel. (2) Check the quantity of printer paper remaining. If red lines appear at the edges of the paper, replace it with a new roll (the red lines indicate there is one meter or less remaining). (3) If there is a sufficient quantity of paper, or after a new roll of paper has been set, close the paper storage cover. 6.1.2 Periodic check The self-diagnostic tests check the status of each function of the equipment on a per-block basis. Conduct periodic checks as directed below. (a) Operating procedure See Section 5.5, Self-Diagnostic Tests, for further details. 47 (b) Self-diagnostic tests Self-diagnostic tests begin with testing of the receiver/demodulator circuit and end with testing of message-processing. The results are printed out, and if the tests detect no abnormalities, the print-out will look like this: ･･････････ Press “ALARM OFF” ････････････ ･･･････････････ Self Test End･･･････････････ ････････････････ ZCZC ID00･･･････････････ THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG 1234567890 . , ?

Checking the receiving tone During tests, if the equipment is normal, a soft tone will be heard. If this tone is not heard, or if the tone is unusually loud, either the CMN-2330 receiver board or the CDJ-2330 is likely to be malfunctioning. b. Checking the alarm buzzer sound During message-processing tests, if the equipment is normal, the alarm buzzer will sound. This alarm can be deactivated by pressing the ALARM OFF switch. If the alarm does not sound or if it is unusually loud, either the CMN-2330 receiver board or the CDJ-2330 main processor board is likely to be malfunctioning. After the alarm has sounded, if it cannot be deactivated using the ALARM OFF switch, either the H-7SZJD0002A main switch or the CDJ-2330 main processor board is likely to be malfunctioning. c. Lamp tests The lamps on the front panel blink for about three seconds prior to the start of the message-processing tests. During the tests, if the equipment is normal, all LEDs other than POWER will blink at intervals of about 0.5 seconds. If blinking is abnormal, the H-7SZJD0002A main switch or the CDJ-2330 main processor board is likely to be malfunctioning. Also, the alphabetic display unit will display characters A to Z. If the display is abnormal, the CDJ-2330 main processor board is likely to be malfunctioning. 50 6.1.3 Other general maintenance and check items In addition to periodic checks by the self-diagnostic tests, it is recommended to check the following periodically. CAUTION When loading the printer paper, cut the leading edge straight. Uneven cutting may cause the paper to jam.
