Memory backup

The TUN-3.7 uses a battery-less memory backup system
in order to retain radio presets and other settings when it’s
unplugged or in the case of a power failure. Although no
batteries are required, the TUN-3.7 must be plugged into
an AC outlet in order to charge the backup system.

Once it has been charged, the TUN-3.7 will retain the
settings for several weeks, although this depends on the
environment and will be shorter in humid climates.
