2)Memory Scan Mode

If one or more channels are stored in memory, when the SCAN key is pressed, "SCAN" and "MEM" will begin to flash simultaneously on the LCD. If no other key is pressed, the radio will begin scanning all channels currently in memory in three seconds. As with All-Scan, if a signal is received, the scan will stop on the receiving channel until the signal is lost for five seconds or the SCAN key is pressed. To cancel memory scan, press the SCAN key while the radio is scanning.

If you have one or more channels in memory and want to initiate All-Scan, perform the following:

Press the SCAN key. "SCAN" and "MEM" will flash on the LCD. Press the SCAN key again within three seconds and "MEM" will disappear from the LCD leaving only "SCAN" flashing. All-Scan will begin in three seconds if no other key is pressed.

3.3.5 Master Reset

To perform a master reset, press and hold the 16 PLUS key while turning the unit on. This feature clears all channels from memory and programs the 16 PLUS feature back to channel 16.

3.3.6 Monitor Mode

Before entering the Monitor Mode you must first select the WX channel you wish to monitor for the weather alert tone. Next, you must also select a working channel to be monitored for traffic. (Refer to section 3.3 for instruction on channel section).

1)Press WX/INT, then scroll to the desired weather channel with the arrow keys.

2)Press the 16 PLUS key to exit the weather band and return to normal mode.

3)Use the arrow keys to select the desired working channel.

4)Press the MON/1/25 key to begin monitor mode. Press the MON/1/25 key again to cancel Monitor Mode.

As an example, let's say we have selected channel 68 as our working channel, WX2 as our weather channel and the 16 PLUS key is programmed for channel 16.

When MON/1/25 is pressed, the radio begins to scan Priority Channel 16, the working channel 68 and weather channel WX2.

Working Channel

If a signal is received on CH68, the scan will stop on CH68, but continue to monitor 16 PLUS and the selected weather channel every five seconds.

16 PLUS (priority) Channel

If while scanning, a signal is received on the designated 16 PLUS channel, the scanning will stop on 16 PLUS as long as the signal is being received. If the signal ceases for more than five seconds, the scanning will continue.

Weather Channel

Until a weather alert tone signal is received on WX2, the scan will stop on WX2 briefly, but will not give any audio output. When a weather alert tone (1050Hz) is received, the monitor will stop and an audible alarm will sound. When the audio alert ends in five seconds, the emergency weather broadcast will be heard. To silence the alarm, simply push any key.
