4.3. Instalace baterie vysílače

Each HT-1KU handheld transmitter requires two AA batteries for operation.

1. Unscrew the bottom cap of the handheld microphone.
2. Insert two fresh AA batteries, observing the correct polarity (+/-) as indicated inside the battery compartment.
3. Securely screw the bottom cap back onto the microphone.

Poznámka: Always use fresh, high-quality batteries for optimal performance and battery life. Remove batteries if the transmitter will not be used for an extended period.

5. Návod k obsluze

5.1. Zapnutí systému

1. Stiskněte tlačítko MOC button on the front panel of the 4W-1KU receiver. The LCD displays will illuminate.
2. For each HT-1KU handheld transmitter, press and hold its MOC button until the LCD display turns on.

5.2. Channel Selection and Synchronization

The 4W-1KU system offers 1000 selectable UHF frequencies per channel and features an automatic synchronization function.

1. Automatic Channel Scan (Autoscan):
   • On the receiver, select the desired channel (e.g., CH1) using the UP/DOWN buttons.
   • Stiskněte tlačítko SOUBOR button to enter the channel selection menu.
   • Navigate to the "SCAN" option and press SOUBOR. The receiver will automatically scan for a clear, interference-free frequency.
2. Automatic Transmitter Pairing (IR Sync):
   • Once a clear frequency is selected on the receiver, ensure the transmitter you wish to pair is powered on.
   • Align the IR window on the transmitter with the IR Sync window on the receiver (for the corresponding channel).
   • On the receiver, initiate the IR sync process (usually by pressing a dedicated SYNC button or selecting "SYNC" from the menu). The frequency information will be transmitted to the microphone.
   • The transmitter's display should update to show the new frequency, indicating successful pairing.
3. Manual Channel Selection (Advanced): For specific frequency requirements, you can manually select channels on the receiver and then use IR Sync to transfer the setting to the transmitter. Refer to the receiver's LCD menu for detailed manual tuning instructions.

5.3. Nastavení úrovní zvuku

The receiver has individual volume controls for each channel. Adjust these controls to achieve the desired output level for your audio mixer or amplifier. Start with the receiver's volume at a moderate level and fine-tune it on your mixer.

5.4. RF Power Settings (Transmitter)

The HT-1KU handheld transmitters offer selectable RF output power (Hi/Low).

• Hi (+14dBm / 25mW typical): Use for maximum range and in environments with high RF interference.
• Low (+4dBm / 2.5mW typical): Use for shorter ranges to conserve battery life and minimize interference with other wireless systems in close proximity.

To change the RF power setting, access the menu on the handheld transmitter's LCD display using the SET/UP/DOWN buttons.

6. Údržba
