English
All radios produce a strong voice / audio feedback if they are too close to each
other and their volume is set too high. Lower the volume in your radio. Using
earpieces can also help reduce aduio feedback if radios are too close.
Important:: Make sure the radios are OFF before charging them. Leaving them
ON in a Multi-Unit Charger causes strong audio feedback that
damages your radio.
Make sure the PTT button is completely pressed when transmitting.
Confirm that the radios have the same settings and PROFILE ID. Make sure
radios are in the same channel. Make sure you wait to hear for the Talk Permit
Tone before talking. Not doing this will cut out the first few words of the
transmission. Refer to "Transmitting and Receiving" on page 27 for further
information.
Recharge, replace and/or reposition batteries. Refer to "About the Li-Ion
Battery" on page 12.
Obstructions and operating indoors, or in vehicles, may interfere. Change
location. Refer to "Transmitting and Receiving" on page 27.
Radios are too close; they must be at least five feet apart.
Radios are too far apart or obstacles are interfering with transmission.
Refer to "Transmitting and Receiving" on page 27.
