The procedures for calling and writing to the preset memory are described below.
The frequency is displayed for two seconds then PS is displayed for three seconds (if there is no PS,
the frequency is displayed for five seconds), after which the display returns to normal. When a fre-
quency is displayed, the preset number corresponding to the pressed key is displayed, and LCD
indicator “CH” lights.
One station in each of the FM1, FM2, FM3, and AM bands can be stored to one key; therefore, a total
of 24 stations can be stored.
The PI code, PS code, and AF list are also written to the preset memory.
In the initial state after the power is first applied, the following frequencies are written to the preset
memory.

Pressing any one of keys M1 to M6 , then releasing it within two seconds, calls the
contents of the preset memory location corresponding to the pressed key. When one
of these keys is pressed, the LCD panel switches to the frequency display.
Pressing any one of keys M1 to M6 , and holding it down for at least two seconds,
causes the frequency to which the device is tuned to be written to the preset memory
location corresponding to the pressed key. When one of these keys is pressed, the
LCD panel switches to the frequency display or to the preset display when the
frequency is written.
