03-02-2000(IC-2710) Some modification for IC-2710Maximum supported frequency range:●●●VHF, 118-135.995 MHZ RX, 136-174 MHZ TX & RXUHF, 320-399.995 MHz RX, 400-479 MHz TX & RXUHF, 849-869 MHZ & 894-950 MHz RXSee product literature for frequency limits from factory. Please note, these are the "tunable" frequency ranges only. Thereceivers are optimized over 20-30 MHz ranges which have been centered around the ham bands at the factory. Performanceoutaide the ranges defined in the product specification is not guaranteed.AM/FM mode selection (118-135.995 MHz or 320-399.995 MHz RX only:●●●Select an appropriate frequency (left side display only)Push and hold the left side MONI(SQL) switch for about ONE second to toggle AM mode ON or OFF.The symbol "
12-11-2000(IC-2710) Crossband Repeater Operation for the IC-2710Author: Kevin - Kastle@aol.com.MODIFICATION.NETCross Band Repeater Mode:●First, verify D-139 is not present (for non USA Versions only)To ENTER Cross Band Mode:●●●Set the desired frquency, tone, & offset on both bandsPress [VHF} and [UHF] main knobs and the [SET L] key at the same time (An "L" will appear on the display)For zero hang time, also press the [LOW] key with the above three key command.To EXIT Cross Band Mode:●Press [SET] to exit Cross Band ModeRemote Operation (UT-49 DTMF Decoder Unit Required for Remote Operation)1. Set the sub band frequency to receive a control signal (DTMF code).● The optional tone squelch function can be used for the sub band to increase remote control reliability.Password Setup2. Program a 3-digit password into the sub band's code channel 5, if desired: (default is 000)a. Push the desired band's tuning dial.*Each band has separate code channels.b. Push [DTMF] 2 times to turn the pager function ON.* "P" appears in place of the 100MHz digit.c. Push {(VOL)SET] to select the code channel setting display.d. Rotate the selected band's tuning dial to select the desired code channel, 0-5.* Code channel P cannot be used for programming.e. Push [(SQL)MONI] or [(VOL)SET] to select the digit to be programmed.f. Rotate the selected band's tuning dial to set the digit.g. Repeat e and f until the last digit is programmed.h. Push [DTMF] to set the code channel for "receive inhibit" or "receive accept."* When "receive inhibit" is set, "SKIP" APPEARS.* Code channel 0 cannot be set as "receive inhibit."i. Push the selected band's tuning dial to exit the setting displayRemote Operation Continued (UT-49 DTMF Decoder Unit Required for Remote Operation)3. Select the main band by pushing a tuning dial, then set the desired frequency for operation.4. Push [DTMF] one or more times unil "REMO" appears to select standby for the remote control.5. Set the operating frequency of the controller transceiver equal to the sub band frequency of the the IC-2710H.* Make sure a tone frequency is set when using the optional tone squelch function with the IC-2710H.* The external DTMF remote does not accept a control signal on the main band frequency.6. From the controller transceiver, transmit the DTMF code as follows:ENTER REMOTE MODE "REMO":B+XXX (password)+#X-BAND ON:X-BAND OFF:B+XXX(password)+#+DB*B+XXX(password)+#+B*EXIT REMOTE MODE: B*This modification is read 1061 times.top of page
