1. المقدمة
This manual provides instructions for the installation, operation, and maintenance of your Parts Express Coaxial A/B Switch. This device allows you to easily switch between two different 75 ohm F-type coaxial input sources, such as a cable television connection and an antenna, to a single output device like a television or VCR.
المميزات الرئيسية:
- Switches between two 75 ohm F-type coaxial inputs.
- Provides 75 dB isolation for clear signal separation.
- تصميم متين لأداء موثوق.
2. الإعداد والتثبيت
Before installation, ensure all connected devices (television, cable box, antenna) are powered off.
- Identify your input sources (e.g., cable line, antenna coaxial cable) and your output device (e.g., television, VCR).
- Connect the first input source coaxial cable to one of the "IN" ports on the A/B switch.
- Connect the second input source coaxial cable to the other "IN" port on the A/B switch.
- Connect a coaxial cable from the "OUT" port of the A/B switch to the coaxial input of your television or other receiving device.
- Secure all F-type connectors by hand-tightening them. Avoid over-tightening.
- Mount the switch in a convenient location using the integrated mounting tabs, if desired.

3. التشغيل
The Parts Express Coaxial A/B Switch is designed for simple manual operation.
- After connecting all devices as described in the "Setup and Installation" section, power on your television and other receiving equipment.
- To select between your two input sources, move the lever on the front of the switch to the desired position. One position will correspond to "CABLE" and the other to "ANT" (Antenna).
- If your television has a tuner mode setting (e.g., "Cable" or "Antenna"), ensure it matches the selection made on the A/B switch for optimal signal reception. You may need to rescan channels on your TV after switching sources, especially if your TV does not automatically detect the input type.
4. الصيانة
The Parts Express Coaxial A/B Switch requires minimal maintenance.
- حافظ على نظافة المفتاح وخلوه من الغبار. استخدم قطعة قماش ناعمة وجافة للتنظيف.
- Ensure all coaxial connections remain secure. Periodically check and re-tighten if necessary.
- تجنب تعريض المفتاح لدرجات الحرارة القصوى أو الرطوبة.
