    R warning high voltage! Never attach an antenna or internal antenna connector during trans- mission. This may result in an electrical shock or burn. R warning! Never carry the linear amplifier by yourself. At least two persons must carry the linear amplifier since it weights approx. 25 kg (55 lb). R...

    ■ grounding to prevent electrical shock, television interference (tvi), broadcast interference (bci) and other prob- lems, ground the linear amplifier through the ground terminal on the rear panel. For best results, connect a heavy gauge wire or strap to a long earth-sunk copper rod. Make the distan...

    ■ system interconnections 1 or 2 icom 100 w hf transceivers can be connected as exciters to the ic-pw1. Non-icom transceivers can be used, however, band selection will not be synchro- nized for each exciter. See the following diagrams for making connections be- tween the ic-pw1 and an exciter (trans...

    ■ setting the alc levels before first applying power, make sure all connections required for your system are complete by referring to chapter 2. Then, reset the linear amplifier using the following procedure. Note: resetting clears all programmed set- tings to default values. Q make sure the linear ...

    12 3 operation the ic-pw1 uses ci-v frequency data for automatic selection of the operating band. Program the exciter’s address to use this capability as follows: for non-icom exciters, the ic-pw1 cannot be con- trolled using the ci-v function, so this setting is not necessary. For transceivers whic...

    13 3 operation caution: do not operate the ic-pw1 before adjusting the alc levels properly with the [alc adj1] and [alc adj2] pots. (p. 11) it takes 15 sec. For ci-v line initial settings when several ci-v devices (more than 5) are connected to a ci-v line. For ic-781 users with other icom ci-v tran...

    3 operation 14 this linear amplifier has various protection circuits. D alc circuit the alc (automatic level control) circuit automati- cally limits rf output power by controlling the input level of the exciter. This prevents transmission of dis- torted signals when the input signal level exceeds th...
