When BCLO is on, transmitting is available only in the following cases: ✻ When no signals are received ("busy" disappears). ✻ When a tone matches in the TSQ setting. 11 StYP-t Scan (timed/busy channel) switching Choose between Timed scan and Busy channel scan (TIMER/BUSY).
5. Advanced Operations 5. Advanced Operations 5-1 Scanning The frequency number of a signal you wish to receive can be automatically sought by the scan function. When a signal is received, scanning will stop, and resume after a while depending on the setting of the scanning mode. ■ Scanning Modes Timed Scan : After stopping on a busy frequency, scanning resumes when the signal ceases or five seconds later even if the channel remains busy. Busy Channel Scan : Scanning resumes only when the signal ceases.
5. Advanced Operations 5-1-1 VFO Scan Scans the entire band in the VFO mode. 1. Press the V/M key to activate the VFO mode. 2. Press and hold the ▲/▼ keys for 1 to 2 seconds to start scanning. VFO Mode The decimal point blinks during scanning. Scanning direction goes upward by pressing the ▲ key, and downward by pressing the ▼ key. 3. To stop scanning, press the PTT key, the FUNC key or the V/M key. When the MONI key is pressed, scanning stops temporarily and the monitor function is activated.
5. Advanced Operations 5-1-3 Skip Channel Setting Memory channels that have "skip" programmed will not be scanned during memory scanning. Refer to page 17 for the setting method. In the memory channel where a memory skip is programmed, "SKIP" appears on the display. The CALL channel is also a skip channel. 5-1-4 Tone Scan This is a function to help you find the tone signal number of a received tone signal. 1. Press and hold the ▲/▼ keys for 1 to 2 seconds in the tone squelch setting mode.
5. Advanced Operations 5-2 Key Lock This is a function that prevents unintentional operations when the keys are pressed accidentally. 1. Press FUNC key, and press MONI key while "F" icon appears. " " appears to indicate the key lock function is activated. 2. To cancel the key lock, press FUNC key again, and then press MONI key. Reference : When the keys are locked, only the PTT and the MONI keys are active. All other keys are inoperative.
6. Selective Communicating 6. Selective Communicating When communicating with a specific station, the tone squelch (CTCSS) function can be used. Tone squelch is a function that enables you to receive a partner's signal when the transmitted tone frequency matches your station's tone frequency. There are 38 different selectable tone number (frequencies) 26 No. Frequency 1 67.0 No. Frequency No. Frequency No. Frequency 11 97.4 21 136.5 31 192.8 141.3 32 203.5 2 71.9 12 100.0 22 3 74.
6. Selective Communicating 6-1 Tone Squelch 1. Press the FUNC key, then the ▲ key while "F" icon appears. "oF" icon blinks. Press FUNC key then the ▲ key again while "F" icon appears. Blinking "oF" is replaced with a blinking number (tone number : default value is 08). By repeating this process, the display rotates as shown in the figure to the right. 2. Change the Tone Number with ▲/ ▼keys.
7.Special Functions 7. Special Functions 7-1 Theft Alarm The transceiver has a theft alarm function that generates an alarm sound from the speaker when a person not knowing the proper procedures removes the unit.This function is useful when installing the unit in a remote place or in a car. Wiring Cable for Alarm Steering Wheel Alarm Cable Connection Illustration Speaker Terminal Jack Connect the center sleeve with the ground (outer) sleeve. There is no connection to the tip.
7.Special Functions 7-1-1 Connecting and Setting 1. Insert the plug of the alarm cable into the speaker terminal jack. Caution • Position the alarm cable and transceiver firmly so that it will not be easily detached. • Program the CH-SC (for alarm) memory in advance to cancel the alarm (page 12). • Set CH-SC (for alarm) in the state where the squelch is activated. 2. Select "SCr-on" in the Setting mode. "✻" appears on the display. 3. Turn OFF the power switch of the transceiver.
7.Special Functions 7-1-2 Alarm When the cable is pulled out or cut, the alarm will start sounding. While alarming, all of the key operations are disabled including the power switch. However, receiving is activated on the frequency recorded in the CH-SC (alarm channel). ■ How to Stop the Alarm When a signal is received and the squelch is unmuted during the alarm, the alarm is canceled and the unit returns to the "receive" mode (A TSQ setting is also a valid squelch setting).
7.Special Functions 7-1-3 Alarm Delay When this function is set, the alarm starts sounding after an interval. 1. Set the alarm function to "SCr-dL" in Setting mode "14". 2. Insert the plug of the alarm cable, and turn the power of the transceiver OFF. In this setting, the alarm will not sound until 10 seconds after the plug is detached. If the cable is detached during the alarm setting procedure, the alarm will start sounding 10 seconds later.
8. Cloning 8. Cloning 8-1 Cloning When using the cloning function, all setting information (including memory data) of one transceiver (master unit) can be transferred and copied to another transceiver (slave unit) by connecting them with a cable. ■ Connecting the Transceivers Connect the external speaker jacks on both the master and slave transceivers with a commercially available Ø3.5stereo mini plug cable. After connecting them, switch the both units' power ON.
8. Cloning ■Transmitting the Master Data 1. Press and hold the MONI key and press the PTT key three times. "CLONE" appears on the display to indicate the Clone mode is activated. 2. Press the PTT key. "Sd ✻✻✻" is displayed and internal setting information is transferred into the "slave" transceiver. "PASS" appears when the cloning completes. The same data is transmitted by pressing the PTT key while the "PASS" is displayed.
8. Cloning ■ Receiving the Master Data 1."Ld ✻✻✻" appears on the slave transceiver's display while the master data is transmitted. "Ld 078" remains displayed when the cloning is completed. The receiving side cannot recognize whether the data has been transmitted correctly. Check to see if "PASS" is displayed on the transmitting (master) side. 2. Switch the transceiver power OFF. Caution • Do not disconnect the cable while cloning.
9. Maintenance and Reference 9. Maintenance and Reference 9-1 Resetting When you reset the transceiver, all settings are returned to the initial factory (default) settings. 1. Turn the power ON while the FUNC key and V/M key are held down. 2. When all the display indications appear, release the FUNC key. The transceiver enters the VFO mode.
