6Press [M.IN] to store the frequency limits.

¥Pressing [M.IN] overwrites new data on any previous data in that channel.

Note: On some General market versions, the frequency limits must be on the same band or they cannot be stored.

This function restricts the range of the Tuning control to those frequencies included by the Start and End frequencies that were programmed above. One application of this function is to keep your operating within the authorized frequency limits of your license.
