PROGRAMMABLE AUXILIARY FUNCTIONS • Side 1, Side 2, o, , <, and > can be programmed with the auxiliary functions listed below. • Channel Down • Channel Up • Display Character • Group Down • Group Up • Home Channel •...
OPERATING BASICS Switching Power ON/OFF Turn the Power switch/ Volume control clockwise to switch the transceiver ON. Turn the Power switch/ Volume control counter- clockwise to switch the transceiver OFF. Adjusting the Volume Rotate the Power switch/ Volume control to adjust the volume.
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.
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.
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.
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.
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 #.
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.
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. •...
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.
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.
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. •...
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.
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.
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.
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.
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.
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).
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”...
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.
