Vemco VR100 - Additional Transponding Commands; Receiver Power Level Adjustment

VEMCO – VR100 Manual 28 May 2018 51
6.2 Additional Transponding Commands
The common transponding commands used to communicate with a receiver in the field are explained in
section 4.4. The remaining commands, which are explained in this section of the manual, are less commonly
used.
6.2.1 Reading/Changing Receiver Power Level
The power level at which a receiver transmits to the VR100-200 during acoustic communication can be read
and changed while the receiver is deployed. After establishing acoustic communication between the receiver
and the VR100-200 (see section 4.4.1), follow the steps listed below. This does not affect the transmit power
level of the receiver’s sync tag.
STEP 1
Select “Settings…” (#2) from the
main transponding menu.
STEP 2
Select “Power Level” (#1).
STEP 3
Select “Read Power Level” (#1) to view the current power level setting, or
select “Set Power Level” (#2) to change the current power level. If you select
#2, continue to Step 4.
STEP 4
Use the arrow buttons to move the asterisk until it sits beneath the desired
power level. The larger the number, the higher the transmit power (1 Low, 2
Medium, 3 High, 4 Very High). Usually, higher power levels means more
reliable acoustic communication, but high power can cause noise problems
(such as echoes) in the area that actually reduce communication.
Press the right selection button (Send) to send a command to change the
transponding transmit power level.
Press the MENU button to return to the Acoustic Release menu.

Use caution when reducing the transmit power level in the
receiver. If the power level is too low, the VR100-200 may not
detect the receiver.
If the transmit power level needs to be adjusted, adjust the transmit power level
of the VR100-200 before adjusting the transmit power level of the receiver.
