Here is a remedy for error 304 while updating firmware:
From the POWER OFF state, press and hold the meter’s power button for 10 seconds – until the LEDs blink magenta briefly, indicating the meter’s bonding state has been reset. The LEDs will then start blinking blue, waiting for a connection.
Reconnect to the meter, then re-establish the bonding (pairing), and try the update again.
