5.3. Tryk-og-tal (PTT)

To transmit your voice, press and hold the PTT button located on the side of the radio. Speak clearly into the microphone. Release the PTT button to stop transmitting and listen for a response.

5.4. VOX-funktion (håndfri betjening)

The VOX (Voice Operated Exchange) function allows for hands-free communication. When activated, the radio will automatically transmit when it detects your voice, without needing to press the PTT button.

5.5. Remote Emergency Alert

The RT22S includes a remote emergency alert feature. This function typically needs to be assigned to a side button through programming. When activated, it can emit an alarm signal to other radios on the same channel, indicating an emergency situation.

5.6. CTCSS and DCS Tones

CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digitally Coded Squelch) tones help filter out unwanted conversations. When enabled, your radio will only receive transmissions that include the same pre-set tone. This ensures more private and secure communication within your group.

6. Understanding Radio Range

The effective range of a two-way radio is influenced by several factors. While the RT22S has a maximum talking range of 1 mile under ideal conditions, actual performance can vary.

Factors Affecting Radio Range:

• Radio Power (Watts): Higher power generally means longer range.
• Radio Signal Type: Different frequency bands (e.g., FRS, GMRS) have different propagation characteristics.
• Horizon Distance: Radio signals travel in a line of sight. The curvature of the Earth limits range.
• Atmosfæriske forhold: Weather can affect signal propagation.
• Antenne: Antenna quality and type impact range.
• Obstacles and Terrain: Buildings, hills, and dense foliage can block or weaken signals.

Tips to Extend Communication Distance:

• Increase Transmission Power: In theory, doubling transmission power can extend communication distance by approximately 1.4 times.
• Improve Receiving Sensitivity: Adjust the squelch threshold of the walkie-talkie and use a high-gain antenna to improve receiving sensitivity.
• Communicate from a Higher Location: Elevating your position can significantly improve line-of-sight and extend range.
• Keep Your Battery Charged: A fully charged battery ensures optimal power output for transmission.
