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.
ApexPro CH and T14
If all leads fail for more than about 8 seconds, the digital signal processor shuts off the
VCO regulator causing the RF output to be turned off.
Once the leads are reconnected or if a button is pressed, about 1 second is required for
the digital signal processor to power up the VCO regulator. If the leads are still bad
after a button is pressed the VCO regulator will turn off again (the RF turns on for 70
seconds for Verify Leads button press, 15 seconds for the other buttons).
If the transmitter is reporting a synthesizer lock error the VCO regulator will be
turned off.
