READ ALL INSTRUCTIONS carefully and completely before using the transceiver. SAVE THIS INSTRUCTION MANUAL­This instruction manual contains important operating instructions for the transceiver. TABLE OF CONTENTS FOREWORD . [. . . ] · Simplex allows you to contact other portable transceivers directly (portable-to-portable contact). Push the [TALK AROUND] switch one or more times to toggle the function ON and OFF. 13 14 4 PROGRAMMABLE FUNCTIONS CONVENTIONAL OPERATION ` Receiving and transmitting 5 · The emergency call is repeatedly transmitted at pre-programmed intervals. D SmarTrunk IITM functions This transceiver provides SmarTrunk IITM functions. (Optional UT-105 SmarTrunk IITM Logic Board is required. ) The optional UT-105 allows communication over conventional channels or SmarTrunk IITM channels. · Scanning starts when a channel bank for SmarTrunk IITM is selected. (See p. 21 for more detailed operation. ) NOTE: Transmitting without an antenna may damage the transceiver. w Listen for a transmission and adjust [VOL] to a comfortable listening level. · When no transmission is heard, push and hold monitor while adjusting [VOL] (your transceiver may not be programmed with the monitor function). The transceiver is now set to receive desired calls on the selected channel. Transmitting: Wait for the channel to become clear to avoid interference. e While pushing and holding [PTT], speak into the microphone at a normal voice level. · When a tone signalling system is used, the call procedure described at right may be necessary. IMPORTANT: To maximize the readability of your transmitted signal, pause a few sec. after pushing [PTT], hold the microphone 10 to 15 cm from your mouth and speak at a normal voice level. 15 16 5 CONVENTIONAL OPERATION CONVENTIONAL OPERATION 5 ` Call procedure When your system employs tone signalling (excluding CTCSS and DTCS), the call procedure may be necessary prior to voice transmission. The tone signalling employed may be a selective calling system which allows you to call specific station(s) only and prevent unwanted stations from contacting you. q Select the desired Tx code channel or 5-tone code according to your System Operator's instructions. w Push the call switch (assigned to one of the dealer programmable switches: [P0], [P1], [P2], [P3], [S1] and [S2]). e After transmitting a 5-tone code, the remainder of your communication can be carried out in the normal fashion. ` Tx code channel selection Your radio may be programmed for Tx code channel selection. In this case, you can choose a Tx code channel to be transmitted when using the call function (p. Push the Tx code channel switch (assigned to one of the dealerprogrammable switches) to activate the function, then enter digits via the keypad to select the desired Tx code channel. · The selected code channel (containing a pre-programmed 5-tone code) is transmitted when using the call function. ` Manual 5-tone codes Depending on programming, you may be able to send 5-tone codes manually. Push the Tx code switch to activate the function, then enter the desired transmit code (up to 7 digits) using the keypad. [. . . ] · "CL IN" appears automatically in the slave transceiver's display. · When cloning is finished, "CLONE" appears in the master transceiver's display. This will cause a cloning error. r When cloning is finished, turn power off, then on again to return to normal operation. NOTE: Transceiver-to-transceiver cloning can not be done between 40CH version and 100CH version, or CPU Rev. 1. and Rev. 2. 0. Y · While pushing [P3] and [Y], turn the transceiver's power on to enter CPU version check mode. [. . . ]
