BASIC OPERATIONS Switch on / off Transceiver Switch on Transceiver: Under power-off state, turn POWER / VOLUME clockwise till hearing "Click" to switch on the transceiver. The transceiver will announce "Power on" when power-on and announce the current channel. Switch off Transceiver: Under power-off state,turn POWER / VOLUME anticlockwise till hearing "Click"...
BASIC OPERATIONS Receiving You can hear the transmitting party's calling when the channel you are operating is called and the LED light turns green. NOTE: You may not receive the calling if you set a high squelch off level of the transceiver. If current channel has been programmed with signaling, you can only hear the call from a same signaling, other calls can not be heard.
ADVANCED OPERATIONS Squelch Off Pressing the programmed key of Squelch off [PF1]/[PF2], the squelch circuit is not mute and at present you can hear the background noise. Press this key again , the squelch circuit becomes mute. By using this function you can monitor the weaker signal which is hard to receive. Monitor Pressing the programmed key of Monitor [PF1]/[PF2], the transceiver emits "DU"...
ADVANCED OPERATIONS Frequency Reverse Under standby conditions, press the programmed key of Frequency Reverse [PF1]/[PF2], transceiver emits "DU" beep and then comes into frequency reverse state. After that, the current channel RX frequency will be switch to TX frequency, and the CTCSS or DCS signal which has been setup will be also switched.
ADVANCED OPERATIONS Power Switch Under the standby conditions, press the programmed key of "Power Switch" [PF1]/[PF2], transceiver change the current channel power and announces. Call 1/Call 2 Under the standby conditions, press the programmed key of "Call 1/Call 2" [PF1]/[PF2] to transmit the prestored and selected DTMF signaling.
ADVANCED OPERATIONS NOTE: It needs to program the VOX in valid status firstly if you want to turn on this function, otherwise, the above operation is invalid. CTCSS / DCS Encode and Decode When the transceiver is edited with this function, the transceiver hear the calling of the other party. when receive matching CTCSS/DCS signaling.Transceiver with matched CTCSS/DCS or without signaling both can hear your call.
ADVANCED OPERATIONS Radio A Radio B Radio C Radio D ID code of the receiving party is 123 355. If the calling party uses "C23" to call, Radio A and Radio B will receive the call. If the calling party uses"CC5" to call, Radio C and Radio D will receive the call. If the calling party uses "CCC"...
ADVANCED OPERATIONS Busy Channel Lockout When BCL function is enabled, you can not transmit in busy channel. BCL prevents you from interfering with other parties who is using the same frequency point that you select. Under this condition, if you press the [PTT] to transmit, the transceiver will emit beep prompt and return to receiving mode.
ADVANCED OPERATIONS Voice Prompt This function is to identify the radio input operation ,operator error or a fault condition prompts. There are Chinese report or English report. Users can program desired beep by programming software. Battery Save Setup When this function is enabled, the transceiver can efficiently reduce battery consumption. The transceiver will automatically switch on Battery Save Function when not receiving and signal or making any operations.
ADVANCED OPERATIONS Expand Frequency Users can set the expand frequency via programming software, the range of expand frequency is 400~520MHz. Eliminating Tail without signaling When transceiver without CTCSS/DCS, choose this option and write into transceiver to eliminate tail voice. NOTE: The receiver and transmitter must choose this function so that it can eliminate the end voice effective Resume Factory Default Once transceiver works abnormally for wrong operations or wrong programming, users can start this...
