The "Monitor" or "Moni" button

The squelch circuit may keep the sound (audio) turned off if only a weak signal is being

received. So if you want to check to see if there is someone calling you with a weak

signal or if your are receiving a weak signal that is cutting in and out, press the Monitor

(Moni) button to temporarily turn off the squelch circuit. Also, if you do use a Privacy

Code always check to see that a channel is not already in use by holding down the Moni

button for a few seconds before you first transmission.

8) Locking the keypad settings

It is easy to accidentally push a button and mess up all your carefully made settings. To

avoid that, most radios have a lock mode. Usually you have to push Menu/Mode/Select

button, hold it down for several seconds and then a beep sounds plus a small padlock icon

appears on your LCD screen. Then you cannot change the settings unless it is

unlocked. To unlock it push and hold the Menu/Mode/Select button again until it beeps

and the padlock icon goes away.

9) "Ring Alert" or "Call Key"

The Ring Alert or Call Key

The ring alert or call keys send out a ring tone (often several are available) to make the

person receiving the tone notice that they are being called and reply. For some it is

annoying and we usually turn them off for disaster work.

RADIO REGULATIONS

The Federal Communications Commission or "FCC"

The Federal Communications Commission (FCC) is an independent United States

government agency, created, directed, and empowered by Congressional statute. It is

charged with regulating all non-Federal Government use of the radio spectrum

including radio and television broadcasting and all US telecommunications. Some

understanding of the role of the FCC is important to CERT communicators because

of its role in regulation, licensing, monitoring, and enforcement of radio laws and

regulations. This section will explain the important rules governing the FRS and

FRS/GMRS radios that you need to know.

2) The FRS, GMRS and the Amateur Radio Service

In this manual we will deal with three FCC created radio communications "Services"

which are: the Family Radio Service or "FRS", the General Mobile Radio Service or

"GMRS" and the Amateur Radio Service ("ham radio service"). In summary:

An FRS radio is all you need for CERT activities. It requires no license and is

allocated 14 UHF* channels. The radios with only FRS are small. They put out no

more than ½ watt, and cost about ~$15-30

For disaster communication in the ASNC area, tune to FRS Channel 2 (Alternate: Ch 12)

Ham Radio Operators should also tune to Battalion 2 simplex 145.585 MHz, PL 110.9
