3.1.3.1 VR100 Front panel Explanations
The explanations given below correspond with the photo of the VR100 face plate.
A)
Audio speaker:
The speaker allows the pings received from acoustic tags
on the active channel
to be heard when the
VR100 is in Monitor mode (see section 4.2); when the VR100 is not in monitor mode, the audio is
muted. The sound can be muted within the Monitor screen (see section 4.2) and can be adjusted with
the volume buttons.
B)
Detection indicators:
A detection indicator flashes a green light each time a ping is detected by the receiver. Each detection
indicator is numbered and corresponds to a receiver channel (see section 4.3.1). When a ping is
received on a channel, the corresponding detection indicator light will flash. For example, if indicator
2 flashes then we know that channel 2 received a ping.
NOTE: More than one detection indicator can flash at the same time if more than one channel is
active (turned on) and pings are simultaneously received on those channels. For example, if channels
1 through 3 are set up for different continuous tag types on 60 kHz then all three detection indicators
will flash when a ping is received on 60 kHz.
C)
LCD screen and three related buttons:
The LCD screen is used to monitor tags and to configure the VR100. The use of the screen and the
three buttons immediately below it is explained in section 4.
D)
Up/Down buttons:
The up and down buttons are used to move a cursor through a list displayed on the LCD screen (see
section 4.3).
E)
Volume control:
The volume control will increase or decrease the volume of the audio signal heard from either the
speaker or the headphones (see section 3.2.3). The button marked with a plus symbol (+) increases the
volume and the button with the negative symbol (-) decreases the volume. The buttons can be held
down or pressed repeatedly for a larger change in volume. The Monitor screen (see section 4.2)
displays the volume level as “VOLXX” where the XX represents a numeric volume level.
F)
Gain Control:
The gain control buttons will increase or decrease the gain level in steps of six decibels (6 dB). The
button marked with a plus symbol (+) increases the gain by 6 dB and the button with the negative
symbol (-) decreases the gain by 6 dB.
G)
LOG GPS button:
The LOG GPS button is used for manual GPS recordings. Pressing the LOG GPS button while in the
Monitor screen will cause the next valid GPS position to be recorded to the VR100’s memory. If the
GPS is locked at the time the button is pressed, then the position will be recorded within 1 second. If
the GPS is not locked, then it could be much longer before the position is recoded. See section 5.1.1
for more information of GPS. NOTE: Manual GPS readings can only be taken while in the Monitor
screen (see section 4.2).
