PRX-3A
Power for Receiver
Battery voltage, behaviour of the PRX Battery voltage, behaviour of the PRX
The following table contains a brief description of the LED and / or the PRX.
LED
Flashes green directly after switching on Flashing code for battery type
Constant green
Flashes green
Flashes red / green
Constant red
Flashes red, low rate
Flashes red, high rate
Flashes red / green, high rate
The following table shows the behaviour of the PRX and / or the LED in response to various input
voltages (i.e. battery voltage). The table shows a typical response to a battery as it is discharged,
commencing at excessive voltage. The table should be read as follows: "Battery voltage higher /
lower than that stated: PRX responds by ..."
Status Voltage
More than 9V
More than 'Charge battery'
Less than 'Charge battery'
More than 'Charge battery'
Less than 'Low voltage'
More than 'Low voltage'
Less than 'Low voltage' for more than 4 sec.
More than 'Low voltage'
Less than 4.3V
More than 4.3V
Less than 3.3V
More than 3.3V
Less than 3.3 V for more than 2 sec.
* The input voltage may be present at the output for one second; after this the output is
switched off.
** Battery flat.
Status
Voltage above 'Charge battery' (all OK)
'Charge battery' (land now)
A brief voltage collapse to below 'Low voltage'
has occurred (shorter than four seconds)

Battery flat
Battery defective
Input voltage excessive
