RESETTING THE RADIO
If the radio stops responding to button presses or otherwise does not function properly in some cases the radio can be reset to restore normal operation.
To reset the radio: With the radio off, press and hold the “F” button and turn the radio on. Release the “F” button when the radio powers up. (see turning the radio on)
This operation will reset the radio to factory settings and will erase all memory channels that have been programmed.
OPERATING THE HANDS FREE VOX (VOICE OPERATED TRANSMIT)
To get the most use from the “VOX” feature you must first determine what sensitivity level is needed to activate the “VOX” control. Sensitivity is how loud you have to talk to activate the “VOX” circuit. The “VOX” has 6 levels of sensitivity that can be adjusted. The 1 option you can talk in a normal voice with no background noise to activate the “VOX” circuit. The higher level numbers will require increasing voice level to activate the “VOX” circuit. This is useful in noisier areas that might activate the “VOX” without talking. The next adjustment is the delay. This is a function of the “VOX” that keeps the radio in transmit mode after you stop talking. A delay that is set to short will cause the “VOX” circuit to stop between some words. The delay is adjustable to 6 levels. Level 1, the shortest will give about one half second of delay. Increasing the delay value extends the transmitter time to two seconds or more. By activating the “VOX” you only have to talk into the front of the radio or use a headset to make the radio transmit. The PTT (push to talk) button is not functional in “VOX” mode. It is recommended to use a headset when using the “VOX” feature.
