Using the Memory
Frequently used frequencies and settings can be saved in the memory so that you can 
quickly and conveniently operate on present channel. The radio is also equipped with 
the following memory functions:
 · Skips memory channels that you do not wish to receive during scanning ( P.77)
 · Scans only the specified memory channels ( P.76)
 · “Programmable Memory Scan (PMS)” that scans only the specified frequency range 
(in the same frequency band) ( P.79)
The operating frequency and other operational information can be registered to each 
regular memory channel, home channel, or PMS memory channel:
• Operating frequency • Memory tag • Repeater information
• Tone information • DCS information • Transmission power
• Memory skip information
(The operating mode information is not registered to the memory channels)
Writingtothememory
Tip
The information saved in the memory may be lost due to incorrect operation, static electricity or 
electrical noise. Data may also be lost due to component failures and repairs. Make sure to write 
down the information registered in the memories on a piece of paper or by using a micro-SD card.
A total of 500 channel memories each, can be used for Band A and Band B.
1  Switch to the VFO mode
2 Use   to adjust the frequency to be written in the 
memory
3 Press   for one second or longer
  The memory writing screen will be displayed.
  The frequency will be automatically displayed in the 
next empty memory channel.
Tip  Refer to Steps 3 to 12 in “Naming a memory channel” 
(P.66) when assigning a name to a memory channel.
4 Turn   to select a different (if desired) memory 
channel
Tip  The memory channel can also be selected by touching it 
directly.
