Controls the memory function. All receiving channels except weather channels can be stored in this memory. Channel Memory:
First select the channel to be memorized, then hold the MEM/SCAN key down until a beep sounds (approx. 2 seconds). MEMO and the channel number will appear on the LCD. To store more channels, repeat the same procedure. Memory Scan:
Memorized channels can be scanned by simply pressing this key. MEMO blinks and the memorized channels are scanned one by one in an upward direction. This operation is invalid if no channel is stored in the memory. Memory Clear:
To cancel a memorized channel, select the channel to be cleared. Then hold the key down until a beep sounds ( approx. 2 seconds). MEMO will disappear from the LCD.
* Usage of this key in the DSC mode is explained in the DSC_ section. There are two kinds of scan mode; Dual watch and Tri-watch. First pressing of this key selects Dual watch, and pressing again leads to Tri-
watch.. Alternately changes the transmitter output power between 1 watt ( LOW appears ) and 25 watts ( LOW disappears). USA channels 13,17,67 and 77 are automatically set to 1 watt, but channels 13 and 67 can be switched to 25 watts if 1/25 key is pressed while PTT switch is on. Selects DSC operation. See the DSC section for details. Remove the cover, press the key once, then press for 3 seconds or more to send the distress call transmission using the DSC function. See the DSC section for details.
