TROUBLESHOOTING
SYMPTOM — No Power
SOLUTION
•Check batteries. Ensure that the batteries are installed correctly
•The batteries may be weak.
•Replace old batteries with four (4) new AAA alkaline or fully charged Ni- MH or NiCad rechargeable batteries.
SYMPTOM — Weak Reception
SOLUTION
•Press the UP button to increase VOLUME.
•The receiving signal may be weak and/ or out of range. If this happens press the SCAN button to defeat the AutoSquelch .
SYMPTOM — Can Not Change Channels
SOLUTION
•To change channels, press the MOD button until the Channel number flashes on the LCD Screen. Press the UP or DOWN button to change channels.
•Batteries may be weak and need replacement. Replace with new batteries if the BATTERY CHARGE LEVEL indicator is low.
SYMPTOM — Limited Range
SOLUTION
•Batteries may be weak and need replacement. Replace with new batteries if the BATTERY CHARGE LEVEL indicator is low.
•The maximum range will vary depending on terrain and environment. Open fields provide the maximum range, while structures, heavy foliage and use in buildings and in vehicles may limit the range significantly.
•Wearing the radio close to the body, such as in a pocket or on a belt, will decrease range. Change the location of the radio away from the body for optimum range under any conditions.
SYMPTOM — Sound Distortion Problems
SOLUTION
•If you are transmitting, speak in a normal tone of voice, 1 to 2 inches away from the
MICROPHONE.
•If you are receiving, lower the VOLUME to a comfortable level.
•Radios may be too close. Radios must be at least 5 feet apart. Increase your separation distance.
•Radios too far apart. Obstacles may be interfering with transmission. Shorten your operating distance.
