A: 1. Please first confirm if the voice instruction is working. If it is working, which means integratedspeaker is ok.If it is not,please send to our factory to test.
2. Please double check the set up of siren mode. All siren means all sirens including integrated siren will siren when sensors been initiated.
3.When sensors been initiated, main controller is dialing or pickng up call, the integrated siren will not siren to let user talk on the phone, so no siren is normal under this situation.
