trendgraph(homescreen).Whenthereceiverisfullycharged,the

chargesymbolwillbecompletelygray.

NOTE: You will keep getting sensor glucose readings while the

receiver is charging during a sensor session. A Low Battery

warning on the receiver will alert you when it needs to be charged.

Setup Wizard:

Press the SELECTbuttontoturnthereceiveron.TheSetupWizardwill

walkyouthroughthestepstosetyourTime/Date,TransmitterIDand
