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 carr y the linearamplifier 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 GROUNDterminal on the rear panel. For best results, connect a heavy gauge wire or strapto a long earth-sunk copper rod. Make the distance b...

■ System interconnections 1 or 2 Icom 100 W HF transceivers can be connectedas exciters to the IC-PW1. Non-Icom transceivers canbe 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 (transceiv...

12 3 OPERATION The IC-PW1 uses CI-V frequency data for automaticselection of the operating band. Program the exciter’saddress 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 notnecessary. For transceivers which ha...
