Scanning bad bar codes generates a bad scan beep and/or an LED light sequence. In some cases, the receipt of data from the
ring device triggers a good scan beep from the Bluetooth module, and then the rejection of scanned bar code data by the paired
mobile device processing causes a bad scan beep from the paired mobile device on the same data.
See the mobile device specific guide for an explanation of the LED and beep indicators for the paired device. For example, if
you have paired the Bluetooth Ring Scanner with the MX7 Tecton so the MX7 Tecton can manipulate the scanned bar code data
received from the Bluetooth Ring Scanner module, refer to the MX7 Tecton User's Guide for MX7 Tecton LED and beep
explanations.
Note: Bluetooth device connection (or pairing) can occur at distances up to 32.8 ft (10 meters) line of sight. Distances greater
than the line of sight limit will break the connection. Arriving at the limit may cause unexpected beep and/or LED
indications. When the connection is broken, the Bluetooth Ring Scanner Module attempts to reconnect with a previously
paired device for 30 seconds. Move the Bluetooth Ring Scanner Module closer to the target. A disconnected paired
device beeps on reconnect.
