Naudojimo instrukcijos

1. Maitinimo įjungimas/išjungimas

Press and hold the power button (usually marked with a circle and vertical line) located on the front panel until the device powers on or off.

2. Kanalo pasirinkimas

Use the "CH+" and "CH-" buttons on the front panel to select your desired communication channel. The RB645 supports 16 channels.

3. Tiesioginio ryšio (PTT) veikimas

The RB645 features a dual PTT design for ease of use:

• Front PTT: Press the large circular PTT button on the front of the radio to transmit. Release to receive.
• Side PTT: Use the PTT button located on the side of the radio for an alternative transmission method. Press to transmit, release to receive.

4. VOX funkcija (balsu valdomas pokalbių keitimas)

VOX funkcija leidžia perduoti signalą laisvų rankų įranga. Įjungus, radijas automatiškai pradės transliuoti, kai aptiks jūsų balsą.

• Refer to the full user manual (if available) or device settings for specific instructions on how to activate and adjust VOX sensitivity.

5. Triukšmo slopinimo funkcija

Squelch eliminates background noise when no signal is being received. The RB645 offers 0-9 levels of squelch adjustment.

• Higher squelch levels require a stronger signal to open the receiver, reducing unwanted noise but potentially missing weak signals. Lower levels allow weaker signals but may pick up more background noise.
• Adjustment typically requires programming software or specific key combinations not detailed here.

6. Avarinis signalas

Avarijos atveju galite įjungti aliarmo funkciją:

• Press and hold the side button 2 (often the lower side button) to activate both local and remote emergency alarms.

7. Kanalo užraktas

To prevent accidental channel changes, you can lock the channel:

• Press and hold the appropriate button (as indicated by the image, likely a side button) for 3 seconds to lock the channel. Repeat to unlock.
