Adjusting the Transmit Power Press HI/LO/SCRAMBLER to adjust the transmit power. If the transmit power on the currently tuned channel is set to Hi (25W), pressing HI/LO/SCRAMBLER changes it to Lo (1W), and LO appears on the display. If the transmit power on the currently tuned channel is set to Lo, pressing HI/LO/SCRAMBLER changes it to Hi, and HI appears. Important: The radio automatically sets itself to low transmit power if you tune to Channels 13, 67, 75, 76, and other low-power channels. Although you cannot change the transmit power to high on Channel 75 or Channel 76, you can change the transmit power to high on Channel 13 or Channel 67 by holding down Hi/LO/SCRAMBLER while transmitting on those channels. Notes: • You cannot change the transmit power while the radio is set to Scan mode. • The radio automatically sets itself to high transmit power if you use PUSH/SELECT to tune to Channel 16, press 16/9 TRI, or it receives a distress call. The radio sets itself back to low power if you use PUSH/SELECT to select another channel. Using Scan Note: If you hold down STEP/SCAN while the radio is set to WX mode or Coast Guard/ Distress/Hailing mode, it cancels that mode and starts memory channel scanning. Using Triple Watch Scan Triple Watch lets you easily scan emergency channels along with a channel you select. To use Triple Watch scan, hold down STEP/SCAN for about 2 seconds. The radio scans Channel 16, Channel 9, and the current memory channel. TRI appears on the display. Using Normal Scan Normal scan lets you quickly scan and tune only those channels you select. To use normal scan, set the radio to Triple Watch scan then hold down 16/9 TRI for about 2 seconds. The radio scans any channels you saved to its memory and SCANNING appears. Notes: • If you use normal scan, the radio does not scan any emergency channels. Use Triple Watch scan (see "Using Triple Watch Scan") to scan emergency channels. • You must save at least one channel in the radio's memory to use normal scan. See "Saving Channels in Memory" on Page 23 for more information. Using Step Step lets you quickly tune through the channels you saved in the radio's memory. To use step, repeatedly press STEP/SCAN. The radio tunes a channel you stored in the memory each time you press STEP/SCAN. Using Channel Mode Hold down MEM/UIC for about 2 seconds to change the radio mode from USA to INTERNATIONAL to CANADIAN. USA , INT , or CAN appears on the display. Notes: • The radio saves the current channel mode setting when you turn it off then turn it back on. 20 Basic Operation
