Maintenance
K-Y3 Call Button Battery Replacement:
Each K-Y3 call button is powered by a 12V 23A alkaline battery. It is recommended to replace the batteries when the transmit indicator light becomes weak or the signal distance noticeably shortens.
- Use the provided opener tool to carefully open the call button casing.
- Remove the old 12V 23A alkaline battery.
- Insert a new 12V 23A alkaline battery, ensuring correct polarity.
- Close the call button casing securely.
Troubleshooting
Signal Range Issues:
- Antenna Extension: Ensure the antenna on the K-4-C display receiver is fully extended for the most optimal signal range.
- Metal Obstructions: Installing the table call system on or near metal walls or surfaces can significantly affect the signal range. Relocate the display receiver if possible to an area free from large metal obstructions.
- Battery Strength: A weak battery in the call button can reduce its transmission range. Refer to the "Maintenance" section for battery replacement instructions.
