PANEL DESCRIPTION q POWER SWITCH [POWER] (p. 11) Push momentarily to turn power ON. w TRANSMIT INDICATOR [TRANSMIT] (p. 13) Lights green while transmitting. During transmission, a humming may sound depending on the output power. This is caused by the large current produced by the power supply and does not indicate equipment malfunction. e ANTENNA TUNER INDICATOR [TUNER] (p. 13) • Lights while the antenna tuner is activated. • Blinks while tuning and the SWR becomes 1.5:1 or greater on the 50 MHz band.

2 INSTALLATION AND CONNECTIONS ■ Unpacking ■ AC power cable connection After unpacking, immediately report any damage to the delivering carrier or dealer. Keep the shipping cartons. A suitable AC power plug must be connected to the AC power cable end. See the diagram below for connection procedures. AC input voltage is automatically selected. For a description and a diagram of accessory equipment included with the IC-PW1, see UNPACKING on p. ii of this manual.
INSTALLATION AND CONNECTIONS 2 ■ Grounding To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, 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 distance between the GROUND terminal and ground as short as possible.
2 INSTALLATION AND CONNECTIONS ■ 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 synchronized for each exciter. See the following diagrams for making connections between the IC-PW1 and an exciter (transceiver). See p. 5 for AC power cable connection.
INSTALLATION AND CONNECTIONS 2 The following connections also apply to transceivers having multiple antenna connectors for specified bands (e.g. IC-726, IC-729, etc.
2 INSTALLATION AND CONNECTIONS NOTE: The specifications for the SEND relay are 5 V DC 0.1 A. If this level is exceeded, a large external relay must be used. • Using 1 Icom and 1 non-Icom exciters (transceivers) To an antenna Be sure to connect the cable to the 7-pin ACC(2) jack.
INSTALLATION AND CONNECTIONS 2 ■ Separating the remote controller The control section of the linear amplifier can be separated from the main body, doubling as a remote controller. It can be placed on the exciter or in another convenient place. y Replace the control cable with the supplied separation cable through the cable hole. Use the shorter end (from the bushing) to connect to the remote controller. Control cable q Disconnect the AC power cable.
3 OPERATION ■ When first applying power (CPU resetting) 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 settings to default values. If the controller’s power is supplied from non-Icom exciters or auxiliary power supply (p. 9), turn the exciter or auxiliary power supply ON while pushing [UP] and [DOWN] to reset the CPU.
OPERATION 3 ■ Programming the CI-V address 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: w Rotate the Icom exciter’s tuning dial until the [INPUT z] light continuously lights. e Push [POWER] to turn the IC-PW1 power OFF and complete the setting. For non-Icom exciters, the IC-PW1 cannot be controlled using the CI-V function, so this setting is not necessary.
3 OPERATION ■ 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 transceivers: Turn the IC-781 power ON before turning the IC-PW1 and other transceiver power ON and keep the IC-781 power ON during operation.
OPERATION 3 ■ Antenna tuner operation The built-in automatic antenna tuner can match the antenna feed line impedance to 50 Ω when the feed line impedance is within 16.7 to 150 Ω for HF bands (VSWR 3:1) or within 20 to 125 Ω for 50 MHz bands (VSWR 2.5:1). Once the tuner matches an antenna, the tuning circuit condition is memorized as a preset point for each frequency range (100 kHz steps, 70 ranges).
4 MAINTENANCE ■ Troubleshooting The following chart is designed to help you correct problems which are not equipment malfunctions. PROBLEM POSSIBLE CAUSE SOLUTION REF. Power does not come on when the [POWER] switch is pushed. • Cable connection is faulty. • Check the connection and connection cable pins. pgs. 7–9 • The circuit breaker is turned OFF. • Check for the cause, then turn the circuit breaker ON. p. 3 Sensitivity is low. • The antenna is not connected properly.
