HI-6053 Battery Replacement
During the annual calibration of your HI-6053 at the ETS-Lindgren factory, the
batteries are tested to verify continued operability. If required, the batteries
are replaced at that time. It is rare that you should need to replace the
batteries between calibration checks, but in that event, follow these steps.
1. Turn the HI-6053 off. Verify that the green indicator light is not flashing.
2. Carefully disconnect the fiber optic cables from the
Transmit and
Receive connectors.
3. Remove the two nuts; one on each fiber optic connector.
4. Remove the four screws from the bottom of the electronics housing.
5. Lift the bottom away from the
housing. Wires from the power
button are connected to the
internal circuitry, so carefully
turn the bottom over and place
it to the side, avoiding placing
stress on the wires.
6. A single connector attaches the two boards together. Withdraw the
two boards from the housing at the same time. The boards should
easily slide out of the tracks.
7. Detach the two boards by carefully separating them at the connector,
avoiding damage to the pins.
8. Replace the four AAA rechargeable NiMH batteries, orienting the +/-
ends as indicated.
