  • Page 108: Power Shutdown During Leads Fail

    Troubleshooting Power shutdown during leads fail ApexPro If all leads fail for more than about 8 seconds, the digital signal processor shuts off power supplied to the RF output amplifier. This reduces the battery discharge rate when no data actually transmits. Once the leads are reconnected, about 1 second is required for the digital signal processor to power up the RF circuitry and resume transmitting patient data.
