1)
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 measurements started 3 minutes after switch ON the module
Averaging times: SLEEP mode - 3 minutes; IDLE mode - 1.5 minutes
Communication tester settings: no neighbor cells, no cell reselection
USB interface disabled
