Error events are accompanied by a CE4 Tagger vibration sequence.
LEDs will illuminate to visually signal a change to the user.
A round blue LED ( ) and a triangular red LED ( ) will illuminate under the following conditions:
• Successful tests or operations result in the blue led illuminating until a new operation is performed or until
the screen is exited.
• Unsuccessful tests or operations result in the red LED flashing until a new operation is performed or until
the screen is exited.
• When an error is accepted by the User, the red LED will switch off, and only if a test fails will the red LED
flash.
• The red and blue LEDs will illuminate simultaneously only if the operation has completed but some error
conditions (acknowledged by the user) have been encountered (example: tagging a det with a bad fuse).
• The DetNet Swirl shaped white LED will illuminate to indicate that the CE4 Tagger is charging.
The CE4 Tagger contains an internal Real Time Clock (RTC), which is required for its operation and log keeping.
The user should manually confirm/set the time-zone on the CE4 Tagger.
The time is automatically updated via the internal GPS.
The CE4 Tagger (version 4 and later) is equipped with a Near Field Communication (NFC) reader located on the
rear of the Tagger. NFC functionality will be activated in a future software release.
