To replace the batteries in the Tekelek 9-6140-01 Cellular Ultrasonic Device, please follow these steps:
1. Turn the unit over and remove the "void if removed" sticker from the base of the unit.
2. Untighten the four screws from the base in a diagonal sequence.
3. Remove the screws fully from the base.
4. Stand the unit in an upright position to prevent the batteries from falling out. Separate the top and bottom plastics.
5. Remove the existing batteries and replace them with new batteries, ensuring to observe the correct polarity.
6. Remove the old O-ring.
7. Place the new O-ring on the top plastic, making sure it is seated correctly in the groove.
8. Mate the top and bottom plastics, taking care not to damage the connectors.
Note: The four legs of the top plastic will only fit into the corresponding holes of the bottom plastic in a certain order, ensuring proper alignment of the connectors.
9. Inspect to ensure the O-ring is still seated correctly.
10. Secure the plastics using the four screws in the following sequence:
- Place diagonal screws and tighten initially to 2.5±0.3kgf.cm.
- Again, using diagonal screws, final torque all screws to 7.0±0.3kgf.cm.
11. Once secure, inspect the seal between the plastics to ensure it has been closed correctly and that the O-ring has not been caught between the plastics. There should be a consistent gap of 0.5mm around the full circumference of the unit when closed correctly.
Please refer to the Tekelek 9-6140-01 Cellular Ultrasonic Device Instruction Manual for more detailed instructions and illustrations.
