GETTING ACQUAINTED 1 2 3 4 5 6 7 8 9 10 11 Antenna POWER / VOLUME Switch: To turn on/off the power and adjust the audio level. Jacklight: White is lit when the alarm key is pressed. Emergency Alarm Key (1)Under the standby conditions, press this key for 1 second to enable alarm function. Press this key again to exit the alarm status.This is optional and PC preprogramming is required. (2)Under the standby conditions, press this key to start jacklight, press this key again to turn it off.
GETTING ACQUAINTED Indicator Status and Beep TX/Reading data Transceiver emits a low voltage beep at intervals of 60 seconds, and red light blinks. Red is lit while transmitting or reading the data while programming. RX/Writing data Green is lit whilereceiving or writing the data while programming. Scan DTMF Successfully Decoded Green blinks every second while scanning. Green and red alternatively blinks. A beep sounds when activating a function. Beeps twice when exiting from a function.
BASIC OPERATIONS Switch on / off Transceiver Turn【POWER】/【VOLUME】dial clockwise to power on. Turn it counterclockwise to power off. Adjusting Audio output level Press and release PF2 key to monitor white noise to refer to the current audio level. Turn【POWER】/【VOLUME】clockwise to increase the audio level, counterclockwise to decrease. CAUTION: Never use earphone while adjusting audio level. The max audio output is loud enough to hurt your eardrums.
BASIC OPERATIONS Group Selection By PC-preprogramming, 128 channels can be assigned in total which are divided into 8 groups with 16 channels in each group. If different groups are being programmed, press and hold [PF2] to turn on. Still holding [PF2] for another 2 seconds, it will announce the current group number. Turn the selector knob to choose the desired group. The voice announce will tell you the selected group number.
BASIC OPERATIONS Emergency Alarm Function (PC pre-programming required) Press the emergency alarm key for over 1 second to start the Emergency Alarm Function.Once activated, it will generate alarm sound, start transmitting to send alarm beeps. Turn off then turn on again or pressing Emergency Alarm key again to exit the function.
ADVANCED OPERATIONS The [PF1] and [PF2] keys are programmable by dealer to assign following features by using programming software. NOTE: When programming the following functions, you need to press the [PF1] / [PF2] key for one second till the transceiver beeps and then release the key to operate the programmed function. Call 1/Call 2 DTMF Under the standby conditions, press the programmed key to transmit the prestored and selected DTMF signaling.
ADVANCED OPERATIONS Temporary Deletion of the Interfering Channel from scanning This function can temporarily skip the interfering channel or occupied channel from scan list. When scan stops on one channel, pressing the programmed key ; it beeps and temporarily deletes this channel from the scan list. If only one or two channels are in the scan list, this operation is not available. Restart the transceiver to restore the temporarily deleted channels into the list again.
ADVANCED OPERATIONS Scramble Setup (Encryption) This special audio process can offer a more confidential communications. Under the standby conditions, pressing and holding the programmed key, it beeps and enables Scramble function. Repeat the same operation,it beeps twice and disables. NOTE: This is a simple analog scrambling (inversion scrambling) and the security level is low. Squelch off Pressing the programmed key, squelch opens and the background noise is heard.
ADVANCED OPERATIONS encode/decode setting will be reversed. This ables the user to talk to other users without using the repeater. Press the key again, it beeps twice and Talk-around is deactivated. Note:Under the talk around state, the transceiver can not communicate with other transceivers through repeaters. Frequency Reverse Under the standby conditions, pressing and holding the programmed key, it beeps and activates Frequency Reverse.
ADVANCED OPERATIONS Whisper Under the standby conditions, pressing the programmed key, it beeps and activates whisper function. This feature is handy in quiet place, you can talk in lower voice than usual. Pressing this key again, it beeps twice and exits whisper function. Voice Compander (Reduce Noise & Enhance Audio Clarity) Under the standby conditions, pressing the programmed key, it beeps and activates the function. This feature reduces the back-ground noise and enhances audio clarity.
ADVANCED OPERATIONS Channel Selector Knob Lockout Under the standby conditions,pressing the programmed key, it will announce the current channel number.Enable this function to prevent normal communication failure caused by channel misadjustment. Under the standby conditions, pressing the programmed key, it beeps and locks the channel selector knob. Press the key again, it beeps twice and unlocks the knob.
PRESET OPERATIONS Following features can be set by using dealer-programming software. CTCSS / DCS Encode / Decode It enables the CTCSS/DCS encode/decode setting.Pre-programming is necessary and usually not recommended for general users. Optional Signaling Users can enable or disable the Optional Signaling in every channel by programming software. This Signaling function is similar to CTCSS/DCS which embodies functions as Selective Call, Group Call, All Call, PTT ID, and Remotely stun and Waken.
PRESET OPERATIONS 3.This transceiver is set with 16 groups of DTMF code, users can program and use them flexibly. Busy Channel Lockout BCLO is to restrict transmitting while RX signal is received. When Busy Channel Lockout is set to on, transmission is possible only in the specific conditions (and isn't possible otherwise).The alarm beep sounds if the PTT key is pressed when transmission is prohibited.Busy Channel Lockout mode available by programming software are as follows.
PRESET OPERATIONS Signaling Relations Setup Users can set relations between CTCSS/DCS signal and DTMF signal by programming software. AND: Only when a matching CTCSS/DCS signal and a DTMF signal are received, can calling of other party be heard. OR: As long as a matching CTCSS/DCS signal or a DTMF signal is received, calling of the other party can be heard. Channel Scan Skip Users can choose whether to set current channel as Scan Skip by programming software.
PRESET OPERATIONS Time-out Timer This function stops the transmission automatically when the continuous transmission time exceeds the set time and alerts it with a voice. Time-Out Timer Pre-Alarm This is the alarm that warns the user before TOT stops the transmission. TOT Re-transmitting Time Setup This is the penalty time before resuming the normal operation condition, once TOT stopped the transmission.
BACKGROUND OPERATIONS Priority Scan Setup This transceiver can be set with two priority channels at the same time.Users can set the desired priority scan by programming software. If transceiver set priority scan, under scanning and receiving no signal state, it will scan every channel and also test priority channel at a time. When the nonpriority channel receives signal, it will test priority channel according to flyback time A and flyback time B setup by users.
Recommended installation of earphone microphone Earphone Use a clip to fix with collar. Clip the PTT unit closer to your mouth. Carry the radio on the side or the back of your body, and the cable should go around the back as shown. Clamp the excessive length of cable at your waist.
