A built-in flashlight is located at the top of the radio for convenience in low-light conditions.

• Press the dedicated flashlight button on the side of the radio to turn it on/off.
• Note: Continuous use of the flashlight will reduce battery life.

7. Range and Performance

The effective communication range of your walkie talkies can vary significantly based on terrain, obstructions, and atmospheric conditions. The stated maximum range of 5 miles is achievable under ideal conditions (e.g., clear line of sight, open water).

• Mountain to Valley: Over 5 miles (ideal conditions).
• Open Water: Ideal 3-5 miles.
• Neighborhood/Urban: Up to 1.5 miles (reduced due to buildings and other obstructions).

For optimal range, ensure a clear line of sight between radios. Obstacles like buildings, dense foliage, and metal structures can significantly reduce transmission distance.
