Operating Procedure for Emergency Communications
1. For EMERGENCY communications, set radio to Ch. 9. For non-
emergency communications, select desired Channel by rotating the
CHANNEL UP/DOWN tuning knob until reaching the desired Channel.
Be sure the antenna is properly connected to the radio before transmit-
ting. Prolonged transmitting without an antenna, or use of a poorly
matched antenna, could cause damage to the transmitter.
2. When asking for aid on Channel 9 it is suggested that you request a
REACT base to respond by saying "Break Channel 9 for a REACT base"
and provide the CB DISTRESS DATA (called "CLIP):
CALL SIGN-Identify yourself and vehicle.
LOCATION-Be exact.
INJURIES-Number. Type. Trapped?
PROBLEM- Give details and help required. Air CLIP repeatedly so any
monitor can aid you.
If you don't receive a response on Ch. 9; try Ch.14 or 19.
USE CHANNEL 9 FOR EMERGENCY ONLY
FCC gives the following examples of permitted and prohibited types of
communications for use on Channel 9. These are guidelines and are not
intended to be all-inclusive.
