CONNECTING EQUIPMENT FOR REMOTE CONTROL

Make connections as shown when remotely controlling
equipment.

Note 1:

Voltage is developed across the 100 Ω resistor in the 3.5 V line

in the transceiver. When 2 mA flows, approximately 3.3 V is
developed.

Note 2:

A 10 µF capacitor is not required in the following cases:

When the other equipment has DC blocking capacitors.

When a 2-terminal electret condenser microphone is used.

CONNECTING OTHER EXTERNAL EQUIPMENT

When connecting an external speaker, an external
microphone, or other equipment such as a TNC for
packet radio to the SP jack or MIC jack, refer to the
diagram below.
