19-1205.fm Page 4 Tuesday, August 3, 1999 10:30 AM FCC REGULATIONS FCC LICENSE REQUIRED The Federal Communications Commission (FCC) requires you to have a license before you operate this transceiver. Unless you qualify to operate on the supplied frequencies, you must apply for a frequency through the PCIA (Personal Communication Industry Association), a non-profit organization that assigns frequencies nationwide to help prevent conflicts between different businesses using transceivers in the same area.
19-1205.fm Page 5 Tuesday, August 3, 1999 10:30 AM • You must use this transceiver only for the commercial use of your business, and only when other commercial channels (such as the telephone) are either not available or not practical. • You must always yield the operating frequency to communications that involve the safety of life or property. • You must take reasonable precautions to prevent harmful interference to other services operating on the same frequency.
19-1205.fm Page 6 Tuesday, August 3, 1999 10:30 AM PREPARATION Before you use the transceiver, you must be properly licensed by the FCC. If you are licensed to use one or both of the supplied frequencies, you can immediately use the transceiver.

The charger does not operate at all at temperatures below 32°F or above 113°F. • Never use any other charger to recharge the transceiver’s battery pack. This could permanently damage your transceiver or the battery pack.

19-1205.fm Page 11 Tuesday, August 3, 1999 10:30 AM WHY USE CTCSS? OPERATIONAL HINTS CTCSS (Continuous Tone-Coded Squelch System) helps eliminate interference between different users of the same frequency. When CTCSS is turned on, the transceiver transmits a selected tone with your transmission. This tone is too low for you to hear, but other transceivers can detect it. If CTCSS is turned on and set to the same tone on the receiving transceiver, it only receives those transmissions that include the tone.
19-1205.fm Page 12 Tuesday, August 3, 1999 10:30 AM ADDITIONAL FCC REGULATIONS The Business Radio Service is under the jurisdiction of the Federal Communications Commission (FCC). Any adjustments or alterations that would alter the performance of the transceiver so it no longer meets the original FCC type acceptance or would change the frequency-determining method are strictly prohibited.
