4. Sozlash
4.1 Joylashtirish
Optimal placement is crucial for maximum signal extension. Position the repeater between the wireless transmitter (e.g., call button) and the receiver (e.g., display screen or watch pager) in an area where the signal from the transmitter starts to weaken. Avoid placing it near large metal objects or other sources of electromagnetic interference.
Figure 4: Long Transmitting Distance - Illustrates signal extension through obstacles.
For very large areas or complex layouts, multiple repeaters can be cascaded. Place each repeater within the extended range of the previous one to create a chain of signal amphayot.

4.2 Quvvatga ulanish
- Connect the provided power adapter to the DC 12V charging port on the repeater.
- Quvvat adapterini standart elektr rozetkaga ulang.
- Qizil KUCH indicator light will illuminate, indicating the device is receiving power.
4.3 DIP kaliti konfiguratsiyasi
The 8-bit DIP switch on the back of the repeater is used to set its operating mode or code, ensuring compatibility with your existing wireless calling system. Refer to your specific call system's manual for the correct DIP switch settings. Generally, the repeater's DIP switch settings should match those of the transmitters and receivers it is intended to work with.
- Use a small tool (e.g., a pen tip) to adjust the individual switches to the ON or OFF position as required.
- Ensure the settings are identical to your call system components for proper functionality.

5. Foydalanish bo'yicha ko'rsatmalar
5.1 Asosiy operatsiya
Once the repeater is powered on and configured with the correct DIP switch settings, it operates automatically:
- When a wireless call signal from a compatible transmitter is detected within the repeater's range, the repeater will receive it.
- The repeater then re-transmits the amplified signal. During re-transmission, the green YUBORISH indikator chirog'i yonadi.
- The amplified signal can then reach receivers that were previously out of range or experiencing weak signals.

5.2 Muvofiqlik
The TD021 repeater is designed to be highly compatible with various 433 MHz wireless calling devices, including different types of call buttons and display receivers or watch pagers from Retekess and Tivdio.

6. Xizmat ko'rsatish
- Tozalash: Use a soft, dry cloth to clean the exterior of the repeater. Do not use liquid cleaners or abrasive materials.
- Atrof-muhit: Qurilmani quruq muhitda, to'g'ridan-to'g'ri quyosh nurlaridan, haddan tashqari haroratdan va yuqori namlikdan uzoqroq joyda saqlang.
- Antennalar: Ensure the telescopic antennas are not bent or damaged. Extend them fully for optimal performance.
- Quvvatlantirish manbai: Only use the original power adapter provided with the device.
7. Muammolarni bartaraf qilish; nosozliklarni TUZATISH
7.1 Quvvat yo'q
- Quvvat ulanishini tekshiring: Ensure the power adapter is securely plugged into both the repeater and the electrical outlet.
- Sotuv nuqtasini tasdiqlash: Elektr rozetkasining ishlayotganini tekshirish uchun uni boshqa qurilma bilan sinab ko'ring.
- Quvvat adapteri: Ensure the power adapter is not damaged.
7.2 Signal Not Extending
- DIP Switch sozlamalari: Confirm that the 8-bit DIP switch settings on the repeater match those of your transmitters and receivers. Incorrect settings are a common cause of signal issues.
- Takrorlagichni joylashtirish: Reposition the repeater. It should be placed within the range of the transmitter and also within range of the receiver. Avoid obstacles like thick walls or metal structures.
- Antennalar: Ensure both telescopic antennas are fully extended and oriented correctly.
- Interferentsiya: Move the repeater away from other electronic devices that might cause interference.
- Transmitter/Receiver Functionality: Verify that the original transmitters and receivers are working correctly without the repeater.
7.3 Intermittent Signal
- Masofa: The repeater might be at the edge of the signal range. Try moving it closer to either the transmitter or receiver.
- To'siqlar: Environmental factors such as thick walls, metal structures, or other radio frequency devices can cause intermittent signals. Adjust placement to minimize these obstructions.
- Quvvat barqarorligi: Elektr ta'minoti barqaror va o'zgarmasligiga ishonch hosil qiling.
