User manual ICOM UT-111

[. . . ] - Push to turn the voice scrambler function OFF. NOTE FOR REMOVAL Be sure to resolder above disconnected points, otherwise no TX modulation or AF output is available when you remove the scrambler units. -1- IC-F300/F400/S SERIES MODIFICATION POINTS M Model: IC-F300/S series REAR ANT Main board A and B. A B M Model: IC-F400/S series REAR ANT Main board A and B. B A -2- APPENDIX -1; IC-F3/F4/S SERIES PRECAUTIONS · Some transceiver versions will not be able to have scrambler units installed because of CPU revision and other factors. Please confirm that the transceivers' serial number is over 50000. · UT-109 and UT-111 scrambler units require some PC board modifications. (See below. ) · IC-F3/F4/S series require a #01: Low level type scrambler unit. [. . . ] However, because of voice components, the transceiver can not maintain synchronous mode in rare cases. Selectable value; Standard (Normal operation) Continuous (repeater operation) D TONE START TIMING (UT-111 only) D SCRAMBLER GROUP CODE (UT-111 only) Set the scrambler group code. D SCRAMBLER TYPE (UT-111 only) Set the UT-111 Rolling type scrambler as UT-109 Non-rolling type. As UT-111 and UT-109 have different code settings, they are not compatible. By selecting Non-rolling type in this item, you can use UT-111 as UT-109. Selectable value; Rolling type (UT-111 normal) Non-rolling type (UT-111 functions as UT-109) Tone start timing selects the synchronous tone signal transmit delay time. Set the delay time when the other party's transceiver has power save mode. Selectable value; OFF(default) 0. 300s, 0. 600s, 1. 100s -5- APPENDIX-2; CLONING NOTES (CS-F3 and CS-F300/S) M Setting examples Below examples are not always needed settings, but will be useful in cases after transmitting a synchronous tone to notify operator of times to start talking. M IC-F3/F4/S series Generally, channels with voice scrambler settings should have the power save function in the Memory CH screen turned OFF. When you want to use the voice scrambler function on channels in which the power saver function is ON, set the Tone Start Timing in the Common screen to 1. 100. · For LMR: In the Common 2 screen, set the Tone Start Timing to 1. 100. Selectable value; Rolling type (UT-111 normal) Non-rolling type (UT-111 functions as UT-109) NOTE: This setting is invalid for UT-109. D SCRAMBLER GROUP CODE (UT-111 only) UT-111 has 1020 (4 groups x 255) code numbers for providing higher communication security. NOTE: This setting is invalid for UT-109. -9- IC-F3GT/GS, IC-F4GT/GS SERIES CLONING NOTES M Setting examples Below examples are not always needed settings, but will be useful in cases after transmitting a synchronous tone to notify operator of times to start M IC-F3GT/GS, IC-F4GT/GS series Generally, channels with voice scrambler settings should have the power save function in the Edit Memory CH screen turned OFF. When you want to use the voice scrambler function on channels in which the power saver function is ON, set the Tone Start Timing in the Common 2 screen to 1. 100. · In above case, non-scrambling voice will be transmitted approx. after pushing PTT. M Other notes For communication between F300/F400/S series and F3GT/GS, F4GT/GS series, make sure that the F3GT/GS, F4GT/GS series power saver settings are set to the same values as the F300/F400/S series Tone Start Timing settings. When using the UT-109/UT-111 for non-rolling type scrambling there are 32 available scramble codes. In the memory CH screen, 1 to 255 can be input as codes however, many of these codes are identical (adding 32 to a code results in the same scramble code). The following groups of codes are the same: 1 to 32 (33 to 64) (65 to 96) (97 to 128) (129 to 160) (161 to 192) (193 to 224) (225 to 255) When using the UT-111 for rolling type scrambling similar but different codes will often result in a match. To avoid this, use codes that are sufficiently different (generally speaking codes that are separated by values of 20 or more will not match). When using the UT-111 for rolling type scrambling and a channel is in the scramble ON condition, if a received signal includes no simultaneous tone, the receiving station automatically enters the through condition and the transmission can be monitored. However, when non-rolling type scrambling is set, simultaneous tone are not used and therefore signals from other stations are received with modulation reversed. When using the UT-111 as rolling type scrambler unit to keep the highest level of privacy, the `LOG IN' function provides full time scrambling communications. [. . . ] (See below and next. ) · IC-F30/F31GT/GS, IC-F40/F41GT/GS series require a #02: High AF level type scrambler unit. · The UT-111 may function as the UT-109 through cloning software. · Compatible cloning software: CS-F30G. OPTIONAL UNIT INSTALLATION M Installation Disassemble the some parts before install the scrambler unit. w Unscrew screw b and 2 screws c, then remove the multi-connector cover and rear panel. [. . . ]
