Basic Operation Turning the Radio On and Off Press PWR to turn on the radio. The radio sounds a tone and a screen showing the user MMSI appears if previously set. If you have not set a user MMSI, see "Setting Up a User MMSI" on Page 34. Note:If the radio is turned on for at least 3 seconds after you select a channel, it remembers the last channel you tuned when you turn it off. Press PWR again to turn off the radio. Selecting a Channel Rotate PUSH/SELECT to select a channel. Rotating PUSH/SELECT clockwise tunes forward through the channels, while rotating PUSH/SELECT counterclockwise tunes backward through the channels. The currently-tuned channel appears on the display. If the radio is set to marine mode, channel numbers appear as two digits. If the radio is set to WX mode, channel numbers appear as one digit. Note: If A appears next to a channel number, this indicates the channel is in a simplex mode on the ship station transmit side of an international duplex channel. Transmitting and Receiving To transmit, hold down PTT on the microphone. TX appears on the display. Release PTT to receive. TX disappears. Notes: • If the channel is set to transmit at low power, you can change it to transmit at high power by pressing HI/LO/SCRAMBLER. If you are attempting to transmit on a normally power restricted channel while transmitting, press HI/LO/SCRAMBLER while holding down the PTT switch to overide the restriction. No other key except HI/LO/SCRAMBLER works. • If you transmit continuously for longer than 5 minutes, TX and the channel number blink and the radio stops transmitting. This warns you that PTT might be stuck. To resume transmitting, release PTT then press it again. • The radio cannot transmit on Channel 15 (USA). • If you hold down PTT while turning on the radio, the radio sounds an error tone and TX and the channel number blink. No key except HI/LO/SCRAMBLER works. • You cannot transmit while the radio is set to WX mode or Scan mode. If you press PTT while the radio is set to Scan mode, the radio cancels that mode but does not transmit. • The radio cannot transmit voice data on Channel 70. Only DSC data such as a Distress Call can be transmitted on Channel 70. 18 Basic Operation
