Page 17: Receiving A Standard Call
TELEPHONE CALLS Conventional Operation • If the channel is busy and the Transmit Disable On Busy feature is programmed, the busy tone sounds and the transmitter is disabled (see page 33). • Otherwise, busy and out-of-range conditions are not indicated and speaking can begin when the PTT switch is pressed. -
Page 18: Placing A Telephone Call
TELEPHONE CALLS The telephone calling feature allows you to place and receive tele- phone calls using your transceiver. When placing a call, the number of the person you are calling is dialed after the radio system is accessed. The following information describes how calls are placed and received with an LTR channel (system) selected. -
Page 19: Receiving A Telephone Call
TELEPHONE CALLS 5. After the number is dialed, release the PTT switch (if applicable) and landside ringing (or a landside busy condition) should be heard. When the other party answers, press the PTT switch and respond. The PTT switch must be pressed to talk and released to listen the same as with standard calls. -
Page 20: General Features
GENERAL FEATURES usually five digits long and it must be dialed using a tone-type tele- phone. The first two digits are the home repeater number of the mobile, and the last three digits are a telephone ID code of that mobile. With LTR interconnect equipment, the first digit must be dialed within 5 seconds of hearing the tone, and no more than 5 seconds must elapse between digits or the call is terminated. -
Page 21: Call Indicator
GENERAL FEATURES AUX1 Call Indicator (Yellow) AUX2 Call Indicator The call indicator is the yellow LED to the left of the channel display (see preceding illustration). The purpose of this indication is to show that a call was received while you were away from the vehicle. Each channel can be programmed for this feature, and it then turns on when a call is received on one of those channels. -
Page 22: Home Channel Select
GENERAL FEATURES When transmitting an encrypted call, wait approximately 1 second before speaking. This gives the receiving encryption device time to establish synchronization which ensures that all of the first word is received. If the proceed tone is used (see page 24), two beeps sound instead of one to indicate that an encrypted call is being placed, and speaking can begin as soon as it sounds because it is delayed for the required time. -
Page 23: Option Select
GENERAL FEATURES Auto Off/On Mode Ignition Switch - The horn alert always turns off when the ignition switch is turned on, and always turns on when the ignition switch is turned off (if there is a turn-off delay). Power Switch - The horn alert always reverts to the off condition when power is turned on by the power switch. -
Page 24: Proceed (Clear-To-Talk) Tone
GENERAL FEATURES tion switch is turned off. At the same time, advantages of ignition switch control can be utilized, such as preventing battery discharge that may occur if the transceiver is accidentally left on for an extended period (see “Preventing Battery Discharge” on page 38). Proceed (Clear-To-Talk) Tone This is a short tone that sounds when the PTT switch is pressed to indicate that the radio system has been accessed and speaking can begin. -
Page 25: Time-Out Timer
CHANNEL SCAN Time-Out Timer The time-out timer disables the transmitter if it is keyed continu- ously for longer than the programmed time. It can be programmed for 0.5 - 5.0 minutes or disabled entirely. If the transmitter is keyed continuously for longer than the programmed time, the transmitter is disabled and the intercept tone sounds. -

CHANNEL SCAN lights (see following illustration). Then when scanning is actually occur- ring, “+” is indicated. The microphone must be on-hook for scanning to occur (unless off-hook detection has been disabled by programming). Scan Occurring Scan Enabled (Green) Scan List Status The selected channel can be changed while scanning using the CHL up/down switches in the normal manner. -
Page 27: Scan Delay And Continue Timers
CHANNEL SCAN Saving Scan List Dealer programming determines if changes made to the scan list are saved when power is turned off. If changes are saved, no change occurs when power is turned off; and if they are not saved, the scan list reverts to the programmed default status. -
Page 28: Fixed Transmit While Scanning
CHANNEL SCAN • Before scanning resumes, exit the scan mode by pressing the SCAN option switch. The channel of the call then becomes the selected channel and it is not necessary to change it manually. Note that with this configuration programmed, when a call is received on a channel other than the selected, the display does not indi- cate the channel of a transmission until scanning resumes. -
Page 29: Ltr And Conventional Operating Modes
LTR AND CONVENTIONAL OPERATING MODES LTR AND CONVENTIONAL OPERATING MODES General Each selectable channel can be programmed for LTR or conven- tional operation by your system operator. The operation that is programmed is determined by the type of radio equipment being used in your radio system. -
Page 30: Monitoring Conventional Channels Before Transmitting
LTR FEATURES level is fixed and setting this control has no affect. Conventional features are described starting on page 33. Monitoring Conventional Channels Before Transmitting Regulations require that the channel be monitored before transmit- ting to make sure that it is not being used by someone else. If you were to transmit when someone else is talking, you would probably disrupt their conversation. -

LTR FEATURES and then pressed again. However, you may want to wait a few seconds before making another attempt to allow the other call time to finish. This feature can prevent the accidental interruption of a call in progress. This could happen when the other transmitting party unkeys or if an ID code with a higher priority is transmitted. -

LTR FEATURES system within range. This feature is either enabled or disabled with all LTR telephone calls by programming (it is not user selectable). If this feature is enabled and an out-of-range condition is encountered, it is auto- matically selected when the PTT switch is released. A short tone sounds to indicate that this mode is selected. -
Page 33: Conventional Features
CONVENTIONAL FEATURES on the programming described in “Transmitting In The Scan Mode” on page 27. If no match is found, the channel number does not change and you cannot respond to the call on that ID code. When a call is detected on a block ID, the displayed channel never changes. -

CONVENTIONAL FEATURES down the PTT switch (it must be released to make another attempt). The Transmit Disable On Busy feature can be enabled or disabled on each channel by programming. Occasionally, a busy condition may be detected even though no one is talking. -
Page 35: Miscellaneous
MISCELLANEOUS When a message is detected on a priority channel while listening to a non-priority message, a tone sounds (unless tones have been disabled) and the transceiver changes to that channel to receive the message. When the priority message is complete, the transceiver returns to the previous channel, and if a message is still present, it is received. - Page 36 MISCELLANEOUS • Out-Of-Range - If this tone sounds shortly after pressing the PTT switch, the transceiver may be unable to contact a repeater. The usual cause for this is an out-of-range condition (see “Operation At Extended Range” on page 38). Once this tone sounds, no more access attempts are made until the PTT switch is released and then pressed again.

Page 37: Ltr Telephone Call Tones
MISCELLANEOUS Wrap-Around Tone - This is a two-tone beep that indicates that the highest or lowest channel was displayed and wrap-around has occurred. Error Tone - This is a two-tone beep that indicates that an error condition has occurred. LTR Telephone Call Tones The following tones are generated by LTR interconnect equipment and are heard when making LTR telephone calls. -

MISCELLANEOUS programming performed by your dealer when the radio was set up, not to any programming that you can perform. If a feature is not controlled by a front panel option switch, it is fixed in the mode set by dealer program- ming or not available. -
Page 39: Licensing
MISCELLANEOUS Since power consumption is significantly higher when transmitting, it is good practice to have the vehicle running while transmitting. This ensures that optimum power is being delivered to the transceiver and that the battery does not become discharged. Licensing A government license is usually required to operate this transceiver on the air. - Page 40 Part Number 002-9801-201 11-99hph Printed in U.S.A...
