Specifications

Operation
General
The following instructions present operating procedures specific to the RM500 and RM500R. It is
assumed that the operator is familiar with the common MICOM-3 operating procedures; if necessary,
refer to the “Owner’s Guide, MICOM-3E/3T/3R HF-SSB Transceivers”, Publication 6886867J01, and
to the applicable MICOM-3 Supplements that cover optional features.
Preparations for Operation
1. Set the REMOTE CONTROL switch on the rear panel of the RM500/RM500R to the OFF
(down) position.
2. For the RM500R, set the internal speaker switch to ON (up).
Operating Instructions
1. Turn the radio on by setting its main switch to ON (up).
2. Adjust the volume control to a comfortable listening level.
3. You are now ready to start using the RM500/RM500R. For operating procedures, you may use
the information appearing in the “Owner’s Guide, MICOM-3E/3T/3R HF-SSB Transceivers”,
Publication 6886867J01.
4. To turn the radio off, set its main switch to OFF (down).
Bypassing the 500W Amplifier Section
The internal 500W amplifier section of the RM500/RM500R can be permanently bypassed. In this
case, you can still transmit at a power of up to 125W using the capabilities of the MICOM-3
transceiver which is part of the RM500/RM500R.
You can bypass the 500W amplifier section in case the full transmit power of the RM500/RM500R is
not needed (for example, good communication conditions), to save power (the maximum power
consumption then decreases to approx. 500W), or when a technical problem in the 500W amplifier
section prevents its operation.
To bypass the 500W amplifier section, select NONE on the PROG>RAD>OPTS>ACC menu.
