[. . . ] INSTRUCTION MANUAL VHF TRANSCEIVER UHF TRANSCEIVER iF31GT/GS iF41GT/GS FOREWORD Thank you for purchasing the IC-F31GT/GS, IC-F41GT/GS FM transceiver. READ ALL INSTRUCTIONS carefully and completely before using the transceiver. SAVE THIS INSTRUCTION MANUAL­This instruction manual contains important operating instructions for the transceiver. ABOUT CE CE Versions of the IC-F31GT/GS, ICF41GT/GS which display the "CE" symbol on the serial number seal, comply with the essential requirements of the European Radio and Telecommunication Terminal Directive 1999/5/EC. This warning symbol indicates that this equipment operates in nonharmonised frequency bands and/or may be subject to licensing conditions in the country of use. [. . . ] ily to select the inaudible condition. D TALK AROUND The talk around function changes duplex channels to simplex channels. · Duplex allows you to contact your base station, repeaters, etc. · Simplex allows you to contact other portable transceivers directly (portable-to-portable contact). Push the [Talk Around] switch to toggle the function ON and OFF. 13 4 PROGRAMMABLE FUNCTIONS D DTMF TRANSMISSION This function allows you to send a pre-programmed DTMF code to control a repeater, open another transceiver's squelch, etc. Manual transmission: Push desired digit keys in sequence while pushing [PTT]. · Pushing [PTT] may not be necessary depending on programming. Automatic pre-programmed transmission: q Push the [DTMF Autodial] switch to select DTMF autodial mode, then push [CH Up] or [CH Down] to select the desired channel. D DTMF RE-DIAL FUNCTION This function allows you to transmit the last-used DTMF code at the push of a key. Push the [Re-dial] switch momentarily to activate the function. · The previously transmitted DTMF code is automatically transmitted. · If no code has been transmitted since turning the power ON, this function does not activate. D EMERGENCY FUNCTION The emergency function allows you to send an emergency signal quickly and easily to your Base Station, etc. to activate the emergency function. · The transceiver selects a pre-programmed channel, then sends an emergency signal to your Base Station. · The pre-programmed channel remains selected until a control signal is received from the Base Station, or power is turned OFF. · The emergency call is repeatedly transmitted at pre-programmed intervals. 14 PROGRAMMABLE FUNCTIONS 4 D DISPLAY LIGHTING The function display has 3 backlight conditions. D SmarTrunk IITM functions This transceiver provides SmarTrunk IITM functions. (Optional UT-105 SmarTrunk II TM Logic Board is required. ) The optional UT-105 allows communication over conventional channels or SmarTrunk IITM channels. To toggle SmarTrunk IITM channels and conventional channels, push the [Bank] switch one or more times. · Scanning starts when a channel bank for SmarTrunk IITM is selected. 21 for more detailed operation. ) 15 5 CONVENTIONAL OPERATION ` Receiving and transmitting NOTE: Transmitting without an antenna may damage the transceiver. Receiving: q Push [CH Up]/[CH Down], or rotate [SEL] to select a channel. 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. r Release [PTT] to return to receive. IMPORTANT: To maximize the readability of your transmitted signal, pause a few seconds. After pushing [PTT], hold the microphone 5 to 10 cm from your mouth and speak at a normal voice level. 16 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. · This may not be necessary depending on programming. · Refer to the next page for selection. w Push the call switch (assigned to one of the dealer programmable switches: [P0], [P1], [P2], [P3], [F2] and [F3]). e After transmitting a 5-tone code, the remainder of your communication can be carried out in the normal fashion. Selective calling Non-selective calling 17 5 CONVENTIONAL OPERATION ` Tx code channel selection Your radio may be programmed for Tx code channel selection. [. . . ] r Unscrew 2 screws e, then take off the chassis from the front panel in the direction of the arrow. Be careful!: Flat cable is connected between the MAIN unit on the chassis and front panel. c e a d d b t Install the desired optional unit. NOTE: When installing UT-105 or UT-111, the unit MUST BE pluged into SLOT 1. (Other optional units can be plugged into either slot. ) Slot 2 Slot 1 y Program the necessary information with the cloning software before operation. Please ask your dealer or system operator for details. 23 9 CLONING ` Cloning Cloning allows you to quickly and easily transfer the programmed contents from one transceiver to another transceiver; or data from PC to a transceiver using the optional CS-F30G CLONING SOFTWARE.
