PROGRAMMABLE AUXILIARY FUNCTIONS • Side 1, Side 2, o, , <, and > can be programmed with the auxiliary functions listed below.
OPERATING BASICS ■ Switching Power ON/OFF Turn the Power switch/ Volume control clockwise to switch the transceiver ON. Turn the Power switch/ Volume control counterclockwise to switch the transceiver OFF. ■ Adjusting the Volume Rotate the Power switch/ Volume control to adjust the volume. Clockwise increases the volume and counterclockwise decreases it. • You may need to adjust the volume more precisely while communicating with other parties.
■ Adjusting the Squelch Level Squelch is used to silence the speaker when no signals are present. When squelch is turned OFF, you will hear background noise from the speaker. When it is ON, you will not hear background noise. The squelch level you select determines when squelch will turn OFF and ON. If you select a squelch level that is too high, you will not hear weaker signals. If you select a squelch level that is too low, you will hear background noise between signals.
■ Placing a Call 1 Make sure no parties are currently transmitting on your selected channel. 2 Press the PTT switch and speak into the microphone in your normal speaking voice. • For best sound quality at the receiving station, hold the microphone approximately 1.5 inches (3 ~ 4 cm) from your mouth. 3 Release the PTT switch to receive. ■ Receiving a Call Your dealer may have programmed QT or DQT signalling on your transceiver.
CHANNEL SCAN Scan is useful for monitoring signals on the channels programmed on the transceiver. When scanning, the transceiver checks for a signal on each channel, and only stops on a channel if a signal is present. The transceiver will remain on a busy channel until the signal is no longer present. Your dealer programs the delay time between signal drop-out and scan resumption. If a signal is received during the delay time, the transceiver will remain on the same channel.
■ Priority Scan If your dealer set up a priority channel on your transceiver, the transceiver will continuously monitor that channel while receiving a signal on another channel. When a signal is received on the Priority channel, the transceiver immediately switches to that channel. • “P” appears on the display. The transceiver will remain on the Priority channel until the signal drops out. Your dealer programs the delay time between signal drop-out and scan resumption.
DTMF CALLS ■ Manual Dialling There are two ways to manually call a number: 1) Press and hold the PTT switch, then enter the desired digits on the keypad. • You can enter the digits 0 ~ 9, A ~ D, , and #. (A ~ D may be disabled by your dealer.) • If programmed by your dealer, you do not need to continuously hold the PTT switch. The transceiver will remain in the transmit state for 2 seconds after releasing each key. • While transmitting DTMF tones, the microphone is muted.
■ Storing DTMF Numbers Note: Auto Dialling must first be activated by your dealer. You can store DTMF numbers (16 digits maximum) in each of the 9 Auto Dial memory locations (1 ~ 9). 1 Press the # key. • “D” appears on the display. 2 Enter the desired digits on the keypad. • You can enter the digits 0 ~ 9, A ~ D, , and #. (A ~ D may be disabled by your dealer, however you can still enter them if desired.) When entering “#”, you must first press the PTT switch. • To cancel, press o, •, <, or >.
■ Dialling Stored DTMF Numbers To call a number stored in a memory location: 1 Press the • key. “A” appears on the display. 2 Enter the desired memory location number (1 ~ 9). • The stored digits are displayed. 3 Press the PTT switch. • If programmed by your dealer, no DTMF tone will sound when “D” is transmitted. “D” is used for a pause time. The pause duration is programmed by your dealer. ■ Clearing Stored DTMF Numbers To clear the numbers from a memory location: 1 Press the # key twice.
CODE SQUELCH Code Squelch is enabled or disabled by your dealer. This function turns the transceiver squelch OFF only when it receives the DTMF code that has been set up in your transceiver. Transceivers that do not transmit the correct code will not be heard. Consequently, you can communicate with a specific party without listening to other parties using the same channel. Your dealer may also activate Group Call for your transceiver.
■ Transmitting 1 Press and hold the PTT switch. 2 Enter the code of the transceiver you want to call or enter a Group code on the keypad. • If desired, you can send codes the same way you make DTMF calls {page 16}. Both manual methods can be used or you can store codes in memory, then dial them from a memory location. • “CALL” appears on the display and the LED indicator lights red. 3 Use the transceiver the same as in a regular call; press the PTT switch to transmit and release it to receive.
SELECTIVE CALL Selective Call is enabled or disabled by your dealer. This function is similar to Code Squelch {page 19}. The differences from Code Squelch are: • You can send or receive message codes containing a maximum of 5 digits. • Selective Call turns the squelch OFF only when the transceiver receives a predetermined DTMF code in the correct sequence: 1) A 3-digit ID code 2) A 1-digit Intermediate code 3) A message code (up to 5 digits) Your dealer may also activate Group Call for your transceiver.
■ Receiving When you receive the correct ID and Intermediate codes, squelch turns OFF and you will hear the call. If a message code is also received, the message appears on the display • “CALL” appears on the display and the LED indicator flashes orange. • When you receive a call with your ID code, “C” appears on the display (i.e.- C 12345). • When you receive a call wih your Group code, “A” appears on the display (i.e.- A 12345). • When no message is received, “NO DATA” appears on the display.
■ Transmitting 1 Press and hold the PTT switch. 2 Enter the code of the transceiver you want to call or enter a Group code on the keypad. • Be sure to enter the ID or Group code, followed by the Intermediate code of the transceiver you want to call. If desired, you can also enter a message code of up to 5 digits. • If desired, you can send codes the same way you make DTMF calls {page 16}. Both manual methods can be used or you can store codes in memory, then dial them from a memory location.
2-TONE SIGNALLING 2-Tone Signalling is enabled or disabled by your dealer. This function turns the transceiver squelch OFF only when it receives the 2-tone signal that has been set up in your transceiver. Transceivers that do not transmit the correct tones will not be heard. Your dealer may also activate Group Call for your transceiver. Ask your dealer for details. ■ Receiving When you receive a signal containing the correct tones, squelch turns OFF and you will hear the call.
■ Transmitting 1 Press the key programmed as TX Code Select. • A 2-Tone code appears on the display. 2 Rotate the Rotary encoder to select your desired 2-Tone code. 3 Use the transceiver the same as in a regular call; press the PTT switch to transmit and release it to receive. • When you release the PTT switch, squelch turns OFF and the LED indicator flashes orange. When you receive a signal, the LED indicator lights green. When the signal drops out, the LED indicator flashes orange again.
AUXILIARY FUNCTIONS ■ Selecting an Output Power Each channel is programmed with either high or low output power by your dealer. You can change the output power of only channels programmed as high. When you can reliably communicate with other parties without using high power, select low power by pressing the key programmed as RF Power Lo. Each time you press RF Power Lo, the output power toggles between high and low.
■ Busy Channel Lockout (BCL) The Busy Channel Lockout feature is activated or deactivated by your dealer. When activated, BCL prevents you from interfering with other parties who may be using the same channel that you selected. Pressing the PTT switch while the channel is in use will cause your transceiver to emit an alert tone and transmission will be inhibited (you cannot transmit). Release the PTT switch to stop the tone and return to receive mode.
■ Reverse Your dealer may have programmed the Reverse function instead of the Talk-Around function. When using Reverse, the transmit and receive frequencies are swapped. This means that you will transmit on the “receive” frequency and receive on the “transmit” frequency. The QT/DQT encoding and decoding signals are also reversed, meaning that transmitted signals are encoded using the “decode” signal, and received signals are decoded using the “encode” signal.
■ Monitor Your dealer can program a key with the Monitor function one of four ways: A Press and hold the Monitor key to hear background noise. Release the key to return to normal operation. B Momentarily press the Monitor key to hear background noise. Press the key again to return to normal operation. C Press and hold the Monitor key to deactivate QT, DQT, or 2-Tone signalling. Release the key to return to normal operation. D Momentarily press the Monitor key to deactivate QT, DQT, or 2-Tone signalling.
