3. Persediaan
The UHPPOTE EM4100 125KHz RFID Keyfobs are read-only and do not require programming themselves. Setup primarily involves integrating them with a compatible 125KHz EM ID access control system or RFID reader.
- Verify Reader Compatibility: Ensure your existing access control system or RFID reader operates at 125KHz and supports EM4100 or TK4100 compatible tags.
- Enroll Keyfobs: Follow the specific instructions provided with your access control system or RFID reader to enroll the unique ID number of each keyfob into the system's database. The ID number is printed on the keyfob.
- Kefungsian Ujian: After enrollment, test each keyfob by presenting it to the reader to confirm it grants access or performs the intended function within your system.
Nota Keserasian Penting: These keyfobs are tidak serasi with UHF readers or encrypted card systems such as HID, Indala, Cobra, APCiK, Paradox, Radio, Honeywell, Kaba, Isonas, etc. Attempting to use them with incompatible systems will result in failure to read.

4. Arahan Operasi
To operate the UHPPOTE EM4100 125KHz RFID Keyfob:
- Present Keyfob: Hold the keyfob within the detection range of a compatible 125KHz EM ID RFID reader. The typical detection distance is 2-10mm.
- Tunggu Pengesahan: The reader will typically provide an audible beep, a visual indicator (e.g., LED light change), or both, to confirm a successful read.
- Akses Diberikan: If the keyfob's ID is recognized and authorized by the access control system, access will be granted (e.g., a door will unlock, attendance will be logged).

5. Penyelenggaraan
The UHPPOTE EM4100 125KHz RFID Keyfobs are designed for durability and require minimal maintenance.
- Pembersihan: If the keyfob becomes dirty, wipe it with a soft, damp kain. Elakkan menggunakan bahan kimia yang keras atau pembersih yang kasar.
- Perlindungan: While waterproof and dustproof, avoid prolonged submersion in water or exposure to extreme temperatures to ensure longevity.
- Storan: Store keyfobs in a cool, dry place when not in use.
6. Penyelesaian masalah
- Keyfob Not Reading:
- Ensure the keyfob is within the reader's detection range (2-10mm).
- Verify the reader is powered on and functioning correctly.
- Confirm the keyfob's ID has been correctly enrolled in the access control system.
- Check for electromagnetic interference near the reader.
- Isu ketidakserasian:
- These keyfobs are 125KHz EM4100/TK4100 compatible. They will not work with UHF readers or encrypted systems (e.g., HID, Indala, Cobra). Refer to Section 3 for a detailed list of incompatible systems.
- If your system uses a different frequency or encryption, these keyfobs are not suitable.
- Kerosakan Fizikal:
- Inspect the keyfob for visible damage. While durable, severe impact can affect functionality.
