Status Light (LED)
The red Status Light on the side of the VR2 case flashes based on the task being performed or the status of the
receiver. The flashes can be interpreted using the table below. The Status Light is an LED (Light Emitting
Diode) and has been referred to as such in past documentation.
Status Light Flash (LED) meanings
VR2 LED Flashes
Interpretation of Flashes
No flash
Receiver is not initialized or the battery is
disconnected/depleted
Two quick flashes every 5 seconds
VR2 is in record mode (records any received
pings)
Two quick flashes every 10
seconds
The VR2 memory full
One short flash
An acoustic ping was received
One long flash
A complete detection was written to memory
When the VR2 is powered (see the Battery section), the Smart LED will emit three
quick flashes. After ten seconds, two long flashes will indicate that necessary
information was read from memory and the receiver is ready for initialization. The LED
will not flash again until the receiver has been initialized. When the receiver has been
initialized (record mode), the LED emits two quick flashes every five seconds. A
received acoustic ping will be indicated with a short dim flash from the LED. A long
bright flash following a sequence (6-7) of short flashes indicates that a transmitter ID
code has been received and stored to memory. Two flashes every ten seconds from an initialized receiver
indicates that the memory is full.
1.2.2
Communication Probe Receptacle
The VR2 receiver has a receptacle for the communication probe from the VR
PC computer interface. The receptacle, called the probe hole, is located on
the end-cap and is identified in the first photo on the previous page. The
probe hole is stepped to ensure that the communication probe is inserted
from only one direction. Remove any marine growth from the receptacle
before inserting the probe. Ensure that the probe is inserted until the O-ring
on the probe is fully seated.
