In the United Kingdom a 1750 Hz tone burst at the beginning of each transmission is used. Since use of these tones is required in the U.K. and in Europe the tone encoder is included as standard equipment. Tone frequency selection To select the tone frequency, press the F and the R/TONE.F key. The display will show a operating tone frequency. Press either the A key or the ▼ key momentarily, the frequency will change 1 step up or down. Press the enter key to complete the selection. Tone Squelch operation To actuate the tone squelch function (decode), turn the Squelch control fully counterclockwise past the detent. Squelch will now open only when the radio receives the same subtone frequency. To return to normal noise activated squelch, turn the Squelch control clockwise past the detent. It is a good operating practice to check the frequency before transmitting. A MONITOR switch has been provided for this purpose when using the TONE SQUELCH function. Pressing this switch will open the squelch so you can check for activity. NOTE:- 97.4 Hz is available only for encode.

This allows you to dial a telephone number from your radio and carry out a telephone conversation, much like a car telephone, or cellular telephone. This function requires the use of a DTMF (Dual Tone Multi Frequency) pad. This is also known as a touch tone pad. It operates just like the touch tone pad on your home telephone. In addition to the normal 12 keys that are found on your telephone the transceiver also provides 4 additional keys A, B, C, and D. These keys are required by some repeater systems for various control functions. You should check with the control operator of your repeater to determine if their use is required. A chart is provided that lists the tones that are generated when you press each key. To use the touch tone pad you should first key the radio using the PTT switch. Then simply press the numbers corresponding to the telephone number you want to dial. Some repeaters will require a special sequence of keys to activate the autopatch. Again you should check with the control operator of your repeater for this sequence. After you have pressed the first number key the radio will remain keyed for approximately 2 seconds. This is done so you do not have to hold the PTT switch depressed while dialing. The radio remains keyed after you press each number for this 2 seconds interval. 13 Audio tones (Hz) \Co(umn Row \ 1209 1336 1477 1633 697 1 2 3 F = A 770 4 5 6 M = B 852 7 8 9 ENTER = C 941 ▲ * 0 ▼ # SCAN = D ■ SCAN Scan is initiated by pressing the scan key. The transceiver will stop on a busy channel. When an incoming signal is detected during scanning, the BUSY indicator will light. In order for this function to operate the SQL control must be adjusted to the threshold point. Scan direction can be selected by either the * or the ▼ key before initiating scan. The selected scan mode and scan stop mode indicators will flash ON and OFF during scanning. • SCAN MODES 1. BAND SCAN MODE: Scans the entire band. 2. MEMORY SCAN MODE: Scans the memory channels repeatedly, skipping the vacant channels. 3. PROGRAMMABLE BAND SCAN MODE: Scans between the frequencies stored in memory channels 8 and 9. If the frequency stored in memory channel 8 is the same or greater than in memory 9, or if either or both channels are vacant, scan will proceed over the entire band. If SCAN is initiated while the displayed frequency is outside the range specified in memory channels 8 and 9, scan will proceed outside of the programmed limits. In the BAND SCAN and PROGRAMMABLE BAND SCAN MODE, scan proceeds according to the selected step size. • SCAN STOP AND RESUME MODES 1. SEEK OPERATED SCAN: Scan will stop on a busy channel. Scan will not resume until the' scan key is pressed again. 14 2. TIME OPERATED SCAN: Scan will stop on a busy channel and resume approx. 5 seconds afterwards. Scan will resume even if the station is still present. 3. CARRIER OPERATED SCAN: Scan will hold as long as the signal is present and resume scan after a 2 second delay if the signal drops out. Releasing scan: Press one of the following keys during scanning to clear the scan mode, a)! scan key b) 1 ptt switch ■ BEEP TONE Audible confirmation of microprocessor function is provided in the form of a series of audio beeps. To activate beep tones, press the f key and 2/BEEP key. The radio will then supply audio confirmation according to the chart below. Scale Frequency (Hz) Key operation A 440....
