Standard Horizon HX270S owner manual Wx Key, Scan KEY, Preset KEY, Mem Key

WX KEY

Immediately recalls the last-used NOAA Weather Channel from any chan- nel location. Recalls the previously- selected working channel when the WX key is pressed again.

Secondary use: When the 16/9 key is held and the WX key is pressed, the radio will change modes between the USA, International, and Cana- dian channel bands.

H/L KEY

Toggles the transmitter power level between High (5 Watts), Medium (2.5 Watts), and Low (1 Watt) of output. Does not operate on “low power only” and transmission-inhibit channels.

When operating on Canadian channel 13, or USA channels 13 or 67, pressing this key momentarily toggles the power level from Low power to Medium or High power.

Hold down this key to lock the displayed channel functions (except the H/L, PTT, and SQL keys) so that they are not accidentally changed. The key lock symbol “” will appear, to indicate that the functions are locked. Hold down until the key lock symbol “” disappears to unlock the ra- dio.

SCAN KEY

Starts scanning and Priority scanning of programmed channels. When scanning, press and hold this key to turn on and off Priority scan (P is shown on the left side of the display during Priority scanning).

PRESET KEY

Immediately recalls one of up to eight user preset memories for opera- tion (shown as 1-8 on the LCD). Pressing this key repeatedly scrolls through the preset memory channels.

MEM KEY

Press to select a channel for scanning. Press this key again to delete a memorized channel. (“MEM” appears on the LCD display during memory operation).
