Operating Temperatures
Note: Within the specified operating temperature ranges the board temperature may vary to a
great extent depending on operating mode, used frequency band, radio output power and cur-
rent supply voltage. Note also the differences and dependencies that usually exist between
board (PCB) temperature of the Java module and its ambient temperature.

1. Maximum time to transmit to keep DGL61-W below the automatic thermal restart limit. 50s
Maximum transmit to idle ratio to keep DGL61-Wbelow the automatic thermal restart limit: 1:3
Both condition, max time and ratio, mustn't be violated to keep DGL61-W in a safe operation condi-
tion without thermal restart, e.g. 10/30s, 20/60s etc. If one condition is violated, e.g. transmit time
60s or ratio 1:2, the DGL61-W will automatic restart when it reached the maximum board tempera-
ture (dependent on the transmit level).
Test condition: LTE upload @23dBm, still air.
2. Maximum time to transmit to keep DGL61-W below the automatic thermal restart limit. 30s
Maximum transmit to idle ratio to keep DGL61-Wbelow the automatic thermal restart limit: 1:6
Both condition, max time and ratio, mustn't be violated to keep DGL61-W in a safe operation condi-
tion without thermal restart, e.g. 10/60s, 20/120s etc. If one condition is violated, e.g. transmit time
60s or ratio 1:5, the DGL61-W will automatic restart when it reached the maximum board tempera-
ture (dependent on the transmit level).
Test condition: LTE upload @23dBm, still air.
