> Measured after module INIT (switch ON the module and following switch OFF); applied voltage on BATT+ (w/o INIT) show increased POWER DOWN supply current.
> 2
> Additional conditions: - SLEEP and IDLE mode measurements started 5 minutes after switching ON the module or after mode transition - Averaging times: SLEEP mode - 3 minutes; IDLE mode - 1.5 minutes - Communication tester settings: no neighbor cells, no cell reselection - interface disabled

> Stated value applies to operation without autobauding (AT+IPR≠0).
> 4
> Stated value applies to operation without autobauding (AT+IPR≠0). If autobauding is enabled (AT+IPR=0) average current consumption in IDLE mode is up to 43mA.
