=== RADIO SKILL CHECKLIST: ICOM ===
Here's how to perform all the basic tasks during patrol:
# Install battery - ICOM has rechargeable battery, so remove entire radio from charger.
# Turn on radio - Rotate volume knob.
# Check battery - Immediately after turning on read the display for battery voltage. Normal is about 8.0 volts - if voltage is less than 7.0 take radio out of service - needs new rechargeable battery.
# Check transmit/receive functions - Turn on, and the display should show the TBSP channel. Press the PTT (Push To Talk) button and speak into the microphone. Red light is on during transmit, and green light is on during receive. Ask a fellow patroller to listen, and then transmit back to you.
# Hand Microphone use - Clip on collar or epaulet. PTT on the hand microphone operates the same as the radio.
# Check-in with USFS (Minden and Grass Valley) - Press P0, then press UP or DOWN buttons to find the channel (and repeater) you want, then press PTT button and talk.
# Switch to a Tone if not being received - Use UP or DOWN buttons to get to a different USFS dispatcher/tone channel combination.
