Current Consumption; The Countermeasure For "System Error - Casio EX-Z30 Service Manual

(1) Current consumption (DC in = 3.70 ~ 4.05 [V])
• Make sure that current consumption is less than 250 mA in PLAY mode.
• Make sure that current consumption is less than 350 mA in REC mode.
• Make sure that current consumption is less than 0.5 mA when power is turned OFF.
(2) The battery indicator changes according to the voltages as follows.
• DC in = less than 3.68 ± 0.02V:
• DC in = less than 3.58 ± 0.02V:
• DC in = less than 3.43 ± 0.02V:

THE COUNTERMEASURE FOR "SYSTEM ERROR"

System error may occur when the battery is removed while data is written to the internal memory.
PROCEDURE
1. Initialize the system.
a) Enter the TEST mode.
b) Select "7:ROM UPDATE" and press SET button.
c) Next, select "5:SYSTEM INITIAL" and press SET button.
d) The following message appears.
SYSTEM INITIALIZE
START ...
PUSH OK KEY?
e) Press SET button and System is initialized.
But the message, "SYSTEM ERROR", still appears on the monitor.
2. Write firmware.
Refer to the "1. To update the firmware version" on page 7.
Write the firmware.
If the TEST mode boots automatically, change "USB TCC ON" to "USB TCC OFF".
Replace the Main PCB if the camera does not recover.
