[. . . ] INSTRUCTION MANUAL UHF TRANSCEIVER i400PRO IMPORTANT READ ALL INSTRUCTIONS carefully and completely before using the transceiver. PRECAUTION RWARNING!NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electric shock. NEVER operate the transceiver while driving a vehicle. [. . . ] To temporarily hear all signals (including noise) push and hold [MONI]. Do not use CTCSS GROUP MODE if you want to hear signals on all channels. w Push [MONI] for 1 sec. e Push [MONI] several times until "CT" appears. r Push [DUP] to select "OFF" (group mode OFF). 5 Push [DUP] t Push [MONI] for 1 sec. to exit the individual setting, then push [O] for 1 sec. to exit Set mode. · The under bar indicators disappear.

In case a frequency other than at left is used, sometimes the squelch system may not performed correctly. 16 6 SELCALL OPERATION I Calling operation D TX code channel selection The [MONI] (Call) key (in Function mode) enables you to change the TX code channel with [ ]/[ ] keys. 32 TX code channels can be pre-programmed into the IC-400PRO using the optional CS-400PRO CLONING SOFTWARE. To select a TX code channel: q While in Function mode, push [MONI] (Call) for 1 sec. to enter the TX code channel selection mode. · Push [O] (Bank/Func) for 1 sec. to enter the transceiver into Function mode. I General In addition to the group mode operation for silent stand-by, the SelCall operation is available. SelCall is an abbreviation for "Selective Calling". In Group mode operation, there are 51 ways to make an individual call with CTCSS frequencies versus 100, 000 ways to make an individual call with Selcall using 5tone. SelCall allows you to selectively call another unit that is operating on the same channel. SelCall can also call the entire group on that channel using group call code. The caller station code/name, status message, Answer Back function, automatic scan start function, etc. A variety of functions are available depending on the setting with the CS-400PRO CLONING SOFTWARE. See the help file for setting details. Push [MONI] for 1 sec. The TX code or TX code channel name (if programmed) is displayed. w Push [ ]/[ Push [ ] to select the desired TX code channel. ] or [ ] 17 SELCALL OPERATION 6 e Push [MONI] (Call) to set the TX code channel, and return to Function mode. D TX code number edit The [MONI] (Call) key (in Function mode) enables you to change the TX code contents within the allowable digits. The group call function works by allowing you to edit a special `group code' into the last 2 digits position of the SelCall ID code. To edit a TX code: q While in Function mode, push [MONI] (Call) for 1 sec. to enter the TX code channel selection mode. · Push [O] (Bank/Func) for 1 sec. [. . . ] r Install the scrambler unit as described in the installation of optional UT-108 as on the page at left. t Replace the bottom cover and screws, then re-connect the DC power cable. Front panel MIC UT-108 Front panel DISC NOTE: Be sure to re-solder the above disconnected points when you remove the scrambler units. Otherwise no TX modulation or AF output is available. 39 CONNECTION AND MAINTENANCE 9 I Optional OPC-617 installation Install the OPC-617 as shown below. I Antenna A key element in the performance of any communication system is an antenna. Contact your dealer about antennas and the best places to mount them. I Fuse replacement A fuse is installed in the supplied DC power cable. [. . . ]
