[. . . ] INSTRUCTION MANUAL DUAL BAND FM TRANSCEIVER i2725E FOREWORD Thank you for purchasing this Icom product. The IC-2725E VHF/UHF FM TRANSCEIVER is designed and built with Icom's superior technology and craftsmanship. With proper care, this product should provide you with years of trouble-free operation. We want to take a couple of moments of your time to thank you for making your IC-2725E your radio of choice, and hope you agree with Icom's philosophy of "technology first. " Many hours of research and development went into the design of your IC-2725E. IMPORTANT READ ALL INSTRUCTIONS carefully and completely before using the transceiver. SAVE THIS INSTRUCTION MANUAL-- This instruction manual contains important operating instructions for the IC-2725E. EXPLICIT DEFINITIONS DEFINITION Personal injury, fire hazard or electric shock R WARNING! [. . . ] v Push [SET B(D-OFF)] or [ENT C(T-OFF)] until "DUP" and offset frequency appear. MAIN TX DUP e Push [SET· ] to enter set mode. rPush [SET· ] or [LOW·PRIO] until "DUP" and offset frequency appear. MAIN TX DUP Push M b Push [Y] or [Z] to set the desired offset. M · Direct frequency entry from the keypad is not possible. [LOW·PRIO] [SET· ] "DUP" and offset frequency appear n Push [CLR A(MW)] to exit set mode. NOTE: The offset frequency can be set in a memory/call channel temporarily. However, the set frequency is cleared once another memory channel or VFO mode is selected. To store the offset frequency permanently, overwrite the channel information. tRotate the main band's [DIAL] to set the desired offset frequency. y Push [TONE·DTMF] to exit set mode. 27 MEMORY OPERATION I General description The transceiver has 212 memory channels including 10 scan edge memory channels (5 pairs), and 2 call channels. Each of these channels can be individually programmed with operating frequency (pgs. 27), subaudible tone encoder or tone squelch and its tone frequency (pgs. In addition, a total of 10 memory banks, A to J, are available for usage by group, etc. *except for scan edge memory channels. 5 4 5 D Using the [Y]/[Z] keys MR/CALL Y/Z z Push [BAND] to select the desired band as the main band. c Push [Y] or [Z] to select and set the desired memory channel. · Pushing [Y]/[Z] for 1 sec. · If scan is activated, push [Y]/[Z] again or push [CLR A(MW)] to stop it. I Memory channel selection D Using the tuning dial q Push the desired band's [M/CALL(MW)] several times to select memory mode. · "!" indicator appears Push [M/CALL·MW] to select memory mode. MAIN TX D Using the keypad MR/CALL z Push [BAND] to select the desired band as the main band. v Push 3 appropriate digit keys to input a channel number. · Blank channel can be selected. · Push only 1 appropriate digit key, [MONI 1(BANK)], [SCAN 2(T-SCAN)], [PRIO 3(PTT-M)], [HIGH 4(DTCS)] or [MID 5(DTCSS)] then push M [M(TONE-1)] or [SQLZ #(16KEY-L)] to select scan M edge channels. "M" and "#" can be used for "A" and "b" respectively. Y/Z w Rotate the same band's [DIAL] to select the desired memory channel. · Programmed memory channels only can be selected. M "!" appears 28 5 MEMORY OPERATION I Programming a memory channel VFO settings, including the set mode contents such as subaudible tone frequency, offset, can be programmed into a memory channel. w Push the same band's [M/CALL·MW] for 1 sec. · 3 beeps sound · "!" indicator and the memory channel number blink. eRotate the [DIAL] to select the memory channel to be programmed. · Memory channels not yet programmed are blank. r Push the [M/CALL·MW] for 1 sec. to program. · 3 beeps sound · Memory channel number automatically increases when continuing to push [M/CALL·MW] after programming. CONVENIENT Memory programming can be performed in versatile ways e. g. memory channel to the same (or different) memory channel, memory channel to the call channel, etc. [EXAMPLE]: Programming 145. 870 MHz into memory channel 20 (blank channel) via the controller. Push MAIN TX V/MHz SCAN Rotate for setting frequency, etc. MAIN TX Push M/CALL MW for 1 sec. MAIN TX M M " "Beep " Beep " Beep " M Rotate MAIN TX Push MW S.
