GETTING STARTED q Switch the Power ON. Switch the transceiver power ON by turning the Power switch/ Volume control clockwise. • A confirmation tone sounds. When using simplex operation, a single tone sounds. When using semi-duplex operation, two tones sound. Refer to page 32 for details on selecting simplex or semi-duplex operation. To switch the transceiver power OFF, turn the Power switch/ Volume control fully counterclockwise, until a click sounds. w Adjust the Volume.
e Select a Channel. Select a channel from 1 to 15 by pressing the ▲ or ▼ key. • • • A confirmation tone sounds each time you press the ▲ or ▼ key. When you receive a call on your selected channel, you will hear audio from the speaker and the LED will light green. To use a signalling code, refer to “QUIET TALK/ DIGITAL QUIET TALK” on page 11. r Make a Call. 1 Press the MON key to make sure the channel is not in use (refer to page 16).
QUIET TALK/ DIGITAL QUIET TALK QT (Quiet Talk) and DQT (Digital Quiet Talk) are functions that reject signals from undesired parties that are using the same channel as you. You will hear audio from the speaker only when you receive a signal that contains a tone or code matching the one set up on the channel you are using. Likewise, when you transmit on a channel set up with QT or DQT, the receiving station must have a matching tone or code in order to hear your signal.
1 Press the MENU key. • The current setting blinks. 2 Press the ▲ or ▼ key to select your desired value. • The values range from 01 to 38 for QT tones, then proceed to 01 to 83 for DQT codes. When you use a DQT code, the icon appears on the display. • “ ” means you have turned off both QT and DQT. Refer to pages 38 and 39 for the actual QT tones and DQT codes. • 3 Press the MENU key 3 times, or press the PTT, MON, or CAL key to confirm the setting.
SCANNING THE CHANNELS You can scan all the channels of the transceiver to search for a signal. When the transceiver verifies a signal on a channel, it proceeds to check whether or not its QT/ DQT setting matches that which is set up on your transceiver, if you have set a channel with QT/ DQT. If the QT/ DQT matches, the transceiver stops at the channel and opens the squelch so you can listen to the call. If the QT/ DQT does not match, the call is ignored and scanning continues.
5 Press the PTT, MON, or CAL key to exit Setting Mode. To begin scanning: 1 Press and hold the ▲ key for 1 second. • appears on the display. 2 When a signal is detected and the QT/ DQT matches, the channel number appears on the display and blinks. 3 When the signal is no longer present, the transceiver waits for 5 seconds before scanning continues.
REVERT C HANNEL The revert channel is the channel from which you start scanning. So, for example, if you are on channel 1 when you begin to scan, your revert channel is channel 1. During scan, pressing the PTT switch will automatically select the transceiver’s revert channel (in the above example, channel 1) and you will begin transmitting.
MONITORING A CHANNEL When no signals are present, the squelch on the transceiver automatically mutes the speaker so you will not hear background noise. Using the MON key, you can disable the squelch to unmute the speaker at any time. This feature is useful for a variety of reasons: • It allows you to confirm the channel activity so that you don’t make a call while another party is using the same channel. • It allows you to adjust the volume level without having to wait for a call.
VOICE ACTIVATED CONTROL (VOX) Using the VOX feature, you can operate the transceiver hands-free. In order to use this feature, however, you must use an optional headset; VOX will not function with the built-in microphone. For best operation conditions, we recommend you use an optional headset with both an ear piece and a microphone on a boom that rests in front of your mouth. With VOX activated, your voice level will determine when the transceiver transmits.
