FCC Regulations
19-1207.fm Page 8 Friday, November 10, 2000 11:04 AM
Overall, Part 90 states that:
• You must have a valid license before you use the transceiver.
• As licensee, you are responsible for proper operation of all transceivers operating under your license author­ity.
• Y o u ca n let unl icensed person s oper­ate this transmitter, as long as you take precautions to prevent unautho­rized transmissions.
• You must use this transceiver only for the comme rcial use of your busi ­ness, and on ly when othe r commer­cial channels (such as the telephone) are either not available or not practical.

• You must not transmit program
material of an y kind used in connec­tion with commercial broadcasting.
• You must not provide a service that
is normally handled by telephone or telegraph unless such broadcasts involve the safety of life or property or in emergencies such as an earth­quake, hurricane, flood or a similar disaster where normal communica­tion channels are disrupted.
FCC Regulations
19-1207.fm Page 10 Friday, November 10, 2000 11:04 AM
• During each transmission or exchange of transmissions, you must identify your station with the call sign issu ed to you by the FCC, or once each 15 minutes dur ing peri­ods of continuous operation.
• You must keep a written record of any maintenance or modification made to the transceiver, and you must make this record available for inspection upon demand by the FCC.
Violating any of the provisions of Part 90 can result in fines and/or confiscation of equipment.
Your equipment might cause TV or radio interference even when it is operating properly. To eliminate interference, you can try one or more of the following cor­rective measures:

19-1207.fm Page 16 Friday, November 10, 2000 11:04 AM
To ensure maximum range, operate the transceiver with the battery pack fully charged. As the voltage decreases, the range decreases.
Caution:
The supplied 12V DC, 200 mA battery charger was designed specifically for your transceiver. Use only the sup­plied battery charger.
1. Turn

2. Press the antenna down over the jack and turn the antenna’s base clockwise until it locks into place.
3. To detach the antenna, turn the antenna’s base counterclockwise. Then lift off the antenna.
Connecting an Optional Antenna
Although the supplied rubber duck anten­na provides excellent local reception, you can connect an optional external mobile antenna or o utdoo r base s tation a ntenna to your transceiver for better reception of weak signals. The antenna jack on the top of the transceiver makes it easy to use the tran sceiver with a varie ty of an­tennas. Your local RadioShack store sells a variety of antennas.

USING THE BELT CLIP
The supplied belt clip lets you easily at­tach the transceiver to your belt.
Slide the belt clip onto the tab at the back of the transceiver until it clicks. To re­move the clip, pull up on its middle tab and slide it down.
CONNECTING AN EARPHONE/EXTERNAL SPEAKER
To listen privately or to hear better in a large area such as a warehouse, you can pull up the rubber cover on the

Listening Safely
To protect your hearing, follow these guidelines when you use an earphone.
• Set the volume to the lowest setting
before you begin listening. After you begin listening, adjust the volume to a comforta ble level.
• Do not listen at extremely high vol-
ume levels. Extended high-volume listening can lead to permanent hearing loss.
• Once you set the volume, do not
increase it. Over time, your ears adapt to the volume level, so a vol­ume level that does not cause dis-

comfort might still damage your hearing.
Traffic Safety
Do not use an earphone with your trans­ceiver when operating a motor vehicle or riding a bicy cle in or near traffic. Doing so can create a traffic hazard and could be illegal in some areas.
If you use an earphone with your trans­ceiver while riding a bicycle, be very careful. Do not listen to a continuous broadcast. Even though some earphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.

1. Set your transceiver to a UHF busi­ness band frequency (see “Setting a UHF Business Band Frequency” on Page 23).
2. Select a quiet tone frequency then set the DIP switches to that fre­quency (see “Using a Quiet Tone Frequency” on Page 29).
You can select one quiet tone frequency at a time. If you do no t want to us e a qui et tone frequency, skip Step 2.

ABOUT QUIET TONE
Quiet tone helps eliminate interference between different users of the same fre­quency, letting you talk and listen to peo­ple who are using other transceivers set to the same frequency and quiet tone code. This is like having a sub-channel within a channel, giving you greater com­munication flexibility. When you set a qui­et tone code — there are 38 to choose from — and turn on your transceiver’s quiet tone, the transceiver transmits a tone with your transmission, letting you communicate with anyone who has a transceiver set to the same frequency
28
Preparation
19-1207.fm Page 29 Friday, November 10, 2000 11:04 AM
and code. This tone is too low for you to hear, but other transceivers can detect it.
Once you set a quiet tone on the trans­ceiver, it only receives those transmis­sions that include the same tone. If two different groups operate transceivers in the same area on the same frequency, they do not hear ea ch oth er’ s broadcast if they both use quiet to ne and ea ch selects a different quiet tone.
