Detection Error Code Display
The following error codes shown in the display window during banknote detection
indicate the type of detection error and the reason the note was rejected.
Important Notices
• If the machine works abnormally, check the following:
Confirm that the power outlet is within specified range (AC 100V~240V/50~60Hz).
Confirm the power cord is firmly connected to the power input on the rear of the
machine.
(If on battery power) Confirm the built-in battery is sufficiently charged by testing the
machine on AC /DC power.
Keep away from strong magnetic fields, which can affect electronic function.
Clean any dust or other contaminant from the sensors.
• If a banknote is blocked while it is being detected, please open the top cover and
remove the banknote to detect it again.
• Please ensure that banknotes have been “smoothed” (e.g. folds and wrinkles
repaired) before inserting. Also, remember that the banknote must be put in straight
– crooked notes will usually be rejected by the CT-550.
Maintenance
This CT-550 is a precise financial detecting equipment which requires periodic
maintenance.
• Keep the banknote detector in a ventilated place and away from magnetic fields.
• Periodically clean the sensors: use a piece of cotton with a small amount of alco-
hol to clean all sensors, rubber wheels and rubber synchronous belts. Be sure not to
expose the sensors to sharp or hard articles in order to avoid damage to them.
• Do not disassemble the detector. Doing so will invalidate any warranties provided
on the machine.
