• The VOX Gain can be adjusted from levels 1 to 10 and OFF. • The transceiver announces the VOX Gain level as you adjust it. If OFF is selected, a beep sounds. 5 Press the PTT switch to save the setting. • A beep will sound. • The transceiver announces the new VOX Gain level. 6 Turn the transceiver power OFF and the ON again to activate VOX. Note: . If a speaker/ microphone is connected to the transceiver while the VOX function is switched ON and the VOX Gain level is configured to a higher, more sensitive level, louder received signals may cause the transceiver to start transmission. . When you operate the VOX function, you must use an optional KHS-1 or KHS-21 accessory. 17 BACKGROUND OPERATIONS BACKGROUND OPERATIONS TIME-OUT TIMER (TOT) The purpose of the Time-out Timer is to prevent any caller from using a channel for an extended period of time. If you continuously transmit for a period of time that exceeds the programmed time set by your dealer (default is 1 minute), the transceiver will stop transmitting and an alert tone will sound. To stop the tone, release the PTT switch. Your dealer can program a warning function to alert you before the TOT expires. Continuously transmitting for the time specified by your dealer will cause the warning tone to sound. BUSY CHANNEL LOCKOUT (BCL) 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. Note: Ask your dealer for an explanation on how BCL functions when using QT, DQT, DTMF, or FleetSync signalling. BATTERY SAVE If activated by your dealer, the Battery Save function will decrease the amount of power used when a signal is not being received and no operations are being performed (no keys are being pressed, and no switches are being turned). While the channel is not busy and no operation is performed for 5 seconds, Battery Save turns ON. When a signal is received or an operation is performed, Battery Save turns OFF. 18 LOW BATTERY WARNING Low Battery Warning alerts you when the battery needs to be recharged or replaced. While operating the transceiver, if the battery power becomes low, an alert tone will sound every 30 seconds and the LED indicator will blink red. Replace or recharge the battery pack. CHANNEL ANNUNCIATION When changing the channel using the Channel selector, an audio voice will announce the selected channel number, after you stop changing the channel. (Channel Annunciation can be activated or deactivated by your dealer.) QUIET TALK (QT)/ DIGITAL QUIET TALK (DQT) Your dealer may have programmed QT or DQT signalling on your transceiver channels. A QT tone/DQT code is a subaudible tone/code which allows you to ignore (not hear) calls from other parties who are using the same channel. When a channel is set up with a QT tone or DQT code, squelch will only open when a call containing a matching tone or code is received. Likewise, signals that you transmit will only be heard by parties whose QT/DQT signalling matches your transceiver. If a call containing a different tone or code is made on the same channel you are using, squelch will not open and you will not hear the call. This allows you to ignore (not hear) these calls. Although it may seem like you have your own private channel while using QT/DQT, other parties can still hear your calls if they set up their transceiver with the same tone or code. 19 STUN When the transceiver receives a call containing a stun code, either transmit mode will be disabled, or both receive mode and transmit mode will be disabled. (This function is used when a transceiver is stolen or lost, for example.) Stun is cancelled when the transceiver receives a call with a stun reset code. DUAL-TONE MULT-FREQUENCY (DTMF) SIGNALLING DTMF Signalling is either enabled or disabled by your dealer. This function opens the squelch only when the transceiver receives the DTMF code (3 to 10 digits) programmed in your transceiver. Each transceiver is normally programmed with a unique code. You will not hear calls from transceivers that are not programmed with a matching code. Your dealer may also program a Group Code in your transceiver. Ask your dealer for further details. When you receive a signal containing the correct tones, squelch opens and you will hear the call. • The LED indicator momentarily flashes orange. • To mute the speaker after squelch opens, press the key programmed as Monitor or Monitor Momentary. • Your dealer can program the squelch to close again after a specific time period elapses. • If Transpond for DTMF Signalling is programmed, an acknowledgment signal is returned to the calling station. • If Call Alert for DTMF Signalling is programmed, an alert tone will sound when the correct code is received. 20 FLEETSYNC OPERATION F...
