ApexPro FH Transceiver: Equipment Overview
LED Indicators Function
Upon Power-On, all LED indicators are illuminated for a brief period.
After the specified time period, only those LEDs displaying positive (or
negative) transceiver functions, as described in each section below,
remain illuminated.
Procedure Alarm Silence Status Indicator
The Procedure Alarm Silence Status Indicator is illuminated when the
PAS function is active. The LED flashes while the Procedure Alarm
Silence button is unlocked or the PAS active time is running low. The
PAS button can only be pressed and activated during this unlocked
phase. Refer to the section on “Procedure Alarm Silence (PAS) Button” on
page D-10 for more information.
External Serial Devices (I/O)
The External Serial Device (I/O) LED is illuminated when an external
serial device is connected, detected and maintaining a logical
communication link.
WARNING
Only allow approved accessories to be connected to the
I/O port of the ApexPro FH transceiver when connected
to a patient. Do not have the I/O port connected to a
computer for programming, or for any other means, while
connected to a patient, as it could result in serious injury.
Low Battery (BATT)
The Low Battery (BATT) LED is illuminated while the battery voltage
remains good.The LED flashes will flash when the battery voltage is low.
When the battery power falls below a predetermined value, the
transceiver will automatically power itself off.
NOTE
If the ApexPro FH transceiver is powered on with a battery that
contains very low voltage, then all of the LEDs on the device will
flash on and off simultaneously. Replace the battery in the
transceiver to restore proper transceiver function.
