7.1 Replacing the Main Battery
When your receiver battery needs replacement, you may acquire a new battery from VEMCO and install
it yourself.
WARNING: It is critically 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
HR2 be opened in a controlled environment, and not in the field or on the deck of a boat.
Replacing a battery in the HR2 requires four basic steps:
1. Opening the case (see "Opening the HR2 Case", below )
2. Disconnecting and removing the battery (see "Disconnecting and Removing the
Battery", on page 148 )
3. Inserting the battery (see "Installing and Connecting a Battery", on page 152 )
4. Closing the case (see "Closing the HR2 Case", on page 155 )
IMPORTANT: PLEASE be kind to the environment and dispose of the battery according to your local
regulation.
7.1.1 Opening The HR2 Case
Two steel rods are necessary to properly open and close the case. Every shipment of new HR2
receivers includes a pair of steel rods.
Step 1 - Ensure there is no water on or near the case
Make sure there is
absolutely no water
on or near the case. Water, even in a small quantity,
can damage the internal circuits beyond repair. If the receiver is attached to a wet rope,
remove the receiver from the rope before opening the case.
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.
