Functionality check
Functional Check
Before any tests can be carried out it is vital to check the status of the unit, its batteries
and basic functionality.
The following list is used to achieve this.
1. Inspection
• Casing
• Labels
• Battery Hatch
• Battery Holder
• Battery Contacts
Once the general condition of the DIGICAT is established the self test can then be used to
indicate the basic unit function and state of the batteries.
2. Audio / Visual display test
Upon depressing the trigger the DIGICAT should test the display and speakers by illuminating
each segment in the bar display followed by the mode LEDs and Depth display.
All LEDs must be operative and an audible output must be heard.
3. Battery / Functional self check
If there is no response when the trigger is activated or the low battery illuminates (or
flashes) after the Audio / Visual Display test, the Batteries will have to be replaced. Use alka-
line batteries, replace all of the batteries at the same time.
The Casing should be free of significant damage.
Body labels must be legible and intact. Display label must be
free of damage and tears.
The Hatch must lock into place.
All the battery contacts and springs on the Holder must be free
of corrosion and the holder in good condition.
The Battery pack contacts must be free of corrosion.
