5.2.2
Battery Installation/Replacement
Replacing a battery in the VR2C requires six basic steps: opening the case, removing the old battery,
inserting the new battery, inspecting the O-rings, closing the case and resetting the battery usage indicator.
These steps are identical for the VR2C-69kHz and VR2C-180kHz. Each of these steps is dealt with in detail
in the following sections.
5.2.2.1
Opening the VR2C Case
Before removing battery:
Place the VR2C in Suspend mode prior to
removing the battery to ensure that no
study data is lost.
CAUTION:
Only install new batteries in the
VR2C. If a partially drained battery is
installed, the battery usage indicator will not
accurately reflect the true battery usage!
Remove the locking collar
(identified in photo) on the
external cable.
STEP 1
Grasp the cable at the
connector and pull straight
back to remove the cable
from the VR2C case.
IMPORTANT: Grip the
connector rather than the
cable to reduce strain on the
cable.
STEP 2
It is vitally important that the electronics inside the receiver case
do not come in contact
with any water
or the receiver will be damaged. For this reason, VEMCO recommends the
VR2C be opened in a controlled environment and
not
in the field or on the deck of a boat.
Make sure there is
absolutely no water
on or near the VR2C case.
Water, even in a small quantity, can damage the VR2C internal circuits
beyond repair. If the VR2C is attached to a wet rope, remove the
receiver from the rope before opening the case.
STEP 3
This also means the electronics cannot be exposed to a
sudden change
in temperature and humidity
that will cause condensation to develop on
the electronics and destroy the receiver.

The method used to open
the VR2C case is the
same as shown
regardless of the receiver
frequency.
Only open a VR2C to replace the battery.
