2-2 ID Tag Model V690-D8KR01
2-5
2-2-4 Battery Life Characteristic
The ID tag contains a battery. The charts below show the relation between the ID tag battery life, number of communication bytes and
ambient temperature. The battery life means the time until the battery voltage alarm has been given.
2-2-5 Battery Voltage Alarm Function
When the voltage of ID tag battery becomes low, "7B" is returned to the termination code when a tag communication command (Read
or Write) is executed.
Correct Usage
After the termination code 7B was generated, the ID tag can be used for approximately one month in a normal situation.
However, we recommend you to replace the tag with a new one immediately.
