The Clear-Com CZ11461 BS121 Base Station, also known as the HME DX121 Base Station, is a top - notch solution for wireless communication. Key Features: It can connect to most hard - wired intercom headset jacks for instant wireless communication. With four - wire connectivity, it interfaces with four - wire/matrix intercoms and radio - based communication systems and has an assignable relay closure for advanced functions. The built - in one - port battery charger can charge a remote Communicator battery in under three hours. You can select the frequency range as low band (2401.92 - 2439.936 MHz), high band (2443.392 - 2481.408 MHz), or full band (2400 - 2483.5 MHz). The digital frequency - hopping, spread spectrum (FHSS) encryption technology ensures confidential communication and is approved for worldwide use. It's expandable and compatible with the entire HME DX 200 and 100 series of digital wireless intercom products. The 600 OHM balanced four - wire I/O connection and 200 OHM balanced headset I/O connection both have level adjustment. Technical Specifications: Frequency range is 2400 - 2483.5 MHz, frequency response is 200 Hz to 3.5 kHz. It requires 100 - 240VAC, 50 - 60Hz or 12 - 14VDC power. It can operate in a temperature range of - 4 - 131F (- 20 - 55C). It has a size of 1.62” x 5.50” x 7.88” (4.1cm x 14cm x 20cm) and weighs 1.2 lbs. (.59kg) with battery. The antenna is an external, dual naversity - wave dipole with an R - TNC connector. System distortion is less than 2%. Communication security uses 64 - bit encryption dual slot naversity. Transmission modes are continuous (latched) or push - to - talk (PTT). Transmitter is frequency - hopping, spread spectrum (FHSS) with 100mw burst transmit power, Gaussian filtered FSK and TDM modulation type. Receiver is also frequency - hopping, spread spectrum (FHSS) with RF sensitivity less than - 90dBm w 10 - 3 BER and no FCC license required.
Using the Clear - Com CZ11461 BS121 Base Station is easy. First, connect it to the appropriate power source, either 100 - 240VAC, 50 - 60Hz or 12 - 14VDC. Then, connect your headset to the headset jack for instant wireless communication. If you're using it with a four - wire or matrix intercom system, make the necessary four - wire connections. You can adjust the frequency range according to your needs, choosing from low, high, or full band. When charging the remote Communicator battery, just place it in the built - in charger and it'll be ready in under three hours. Remember to keep the device in a temperature range of - 4 - 131F (- 20 - 55C) to ensure proper operation. For maintenance, keep the device clean and free from dust. Check the antenna regularly to make sure it's properly connected. If you experience any issues, refer to the technical specifications and check for common problems like incorrect frequency settings or power supply issues.
